TI-84 Plus CE Program Components: Alphabetical

ACIDBAS1 is the standalone acids and bases solver/reference program. It covers pH, pOH, [H+], [OH-], Ka, Kb, pKa, pKb, weak acids, weak bases, percent ionization, buffer calculations, Henderson-Hasselbalch acid and base buffer forms, titrations, salt hydrolysis, strong acid/base reference lists, and polyprotic acid concepts. It is designed to help students organize acid-base chemistry more clearly on the TI-84 Plus CE, with built-in help screens and many input checks throughout.

ALGSOL6 is the comprehensive algebra solver. It covers systems, first-degree equations, absolute value equations, function evaluation, linear and quadratic tools, coordinate geometry, geometry-area solving, statistics, deradicalization, angle conversion, and percent calculations. It is the main engine inside the Algebra Solver product.

ALGXEQ1 is the algebra formula and definition library. It includes coordinate geometry, 2D and 3D formulas, factoring rules, binomial expansions, quadratics, linear equations, number sets, algebraic properties, variation, systems and inequality logic, powers and radicals, complex numbers, and logarithm rules. It is a formula/reference counterpart to the more active solver ALGSOL6.

AMINO1 is the amino acid reference library for the 20 standard amino acids. It includes full names, 3-letter abbreviations, 1-letter symbols, chemical classifications, side-chain descriptions, pKa values where relevant, and special notes like Proline's ring structure and Cysteine's disulfide behavior. It is especially useful as a compact biochemistry support reference.

AREA2D is a focused 2D area solver for the TI-84 Plus CE. It covers squares, rectangles, rhombuses/kites, parallelograms, trapezoids, triangles, circles using radius or diameter, sectors in radians and degrees, regular hexagons, and regular polygons using perimeter and apothem. Depending on the shape, students can solve not only for area, but also for missing side length, base, height, radius, diameter, sector angle, perimeter, or apothem. It is a narrower, cleaner geometry-area tool than GEOFIG8 and is useful for students who mainly want quick 2D area work.

CALCEQ10 is the main AP Calculus AB/BC formula and concept reference. It includes derivative and integral libraries, BC topics like series and sequences, Taylor and Maclaurin series, polar and parametric formulas, vectors, limits and the Fundamental Theorem of Calculus, concept help for rules and graph analysis, plus worked U-substitution examples. It is the central anchor file inside the calculus bundles.

DERIV2 is the specialized derivative reference. It contains roughly 58 formulas and procedures, covering the standard rules, trig and inverse trig derivatives, logarithmic differentiation, implicit differentiation, higher-order derivatives, parametric and polar derivatives, vector-calculus formulas, hyperbolic functions, related rates, optimization, linearization, and motion applications. It is one of the deeper single-topic reference files in the calculus lineup.

EMADVJ is the advanced electricity and magnetism suite designed for AP Physics C: E&M, IB HL, and university-level engineering physics. Its major components include AC circuit analysis and phasors, phase lead/lag, mixed impedance building, advanced capacitor and inductor geometry, full series and parallel RLC analysis, resonance and power factor work, wave optics, polarization, Maxwell's Equations, and advanced transformer logic including impedance matching. This is the higher-level companion to EMBASICH.

EMBASICH is the complete foundational E&M solver and reference suite for AP Physics 1, AP Physics 2, and introductory Physics C: E&M topics. Unlike a simple formula sheet, it is a fully interactive solver — students enter values and get computed answers, with the program handling the formula work automatically.

The program is organized into six main sections. Electric Fields covers Coulomb's Law (all four variables), electric field calculations using both F/q and kq/r², electric potential, potential energy, work, electric dipoles with torque and energy, and Gauss's Law for point, line, and plane charge distributions. Circuit Analysis covers Ohm's Law, series and parallel resistor networks, all three power formulas, Kirchhoff's Loop and Junction Rules with interactive element entry, and full RC circuit behavior for charge, current, time constant, and stored energy. Magnetic Fields covers Lorentz force on charges and current-carrying wires, Biot-Savart Law, Ampere's Law for wires, solenoids, and toroids, magnetic flux, and solenoid inductance. Electromagnetism covers Faraday's Law, Lenz's Law, motional EMF, transformer voltage and current ratios, and LR circuit behavior for both growing and decaying current. E&M Unit Conversion is a focused converter for the units students actually encounter in E&M work — force (N, lbf, dyn), energy (J, eV, cal, kWh), power (W, hp, BTU/h), charge (C, e, Ah), current (A, mA, µA), potential (V, mV, kV), electric field (N/C = V/m), and magnetic units (T, G, Wb, Mx). A Memory utility lets students store and recall the last computed result across calculations.

All six trig-dependent solvers (dipole torque and energy, Lorentz force, Biot-Savart, and magnetic flux) include a degree/radian choice at input, so students are not forced to convert angles before entering values. Help screens with formulas and conceptual explanations are available inside each major section. This is the core E&M workhorse for most students before moving into the AC circuits, phasors, and Maxwell's Equations coverage in EMADVJ.

FINMATH1 is the financial-math formula reference. It includes simple and compound interest, continuous compounding, annuities, amortization, bond pricing, depreciation methods, NPV, IRR, payback period, profitability index, and time value of money formulas. It is a broad finance/business reference component.

FREE5 is the free starter bundle program. It includes a quadratic solver, radical simplifier, decimal-to-fraction converter, and algebra solver, along with help screens for each. It functions as an introduction to how the TI-84 programs work and gives new students a low-friction way to test the overall style and usefulness of the catalog before buying.

GASLAWSA is the dedicated gas-law solver component used across chemistry and physics bundles. It covers all six core gas-law relationships — Ideal Gas Law (PV = nRT), Boyle's Law, Charles's Law, Gay-Lussac's Law, Avogadro's Law, and Combined Gas Law — plus the Full Combined Law, which handles all four variables (P, V, n, and T) changing between two states. That last section is particularly useful for problems where gas is escaping, being added, or transferred between containers, and it solves for any of eight variables across both states. The MORE Functions menu adds Dalton's Law for mixed gas total pressure (2–4 gases), RMS velocity, and a built-in Gas Constant R reference with all four R values and STP molar volumes. Every law submenu displays its formula in the header, and built-in help screens cover unit requirements, R value selection, and when to use the Full Combined Law versus the standard Combined Law.

GEOFIG8 is the comprehensive 2D/3D geometry solver. It handles area, perimeter, volume, and surface area for a broad library of shapes, including polygons, circles, sectors, prisms, cylinders, cones, spheres, and pyramids. It is bidirectional, so students can solve for a missing measure from the area or volume when needed.

HABERX2 is a focused chemistry solver centered on the Haber-Bosch process and general thermochemical stoichiometry. It includes energy-from-mass and yield-from-energy calculations for ammonia production, a more general reaction-energy solver for balanced equations, q = mcΔT heat-transfer tools, example walkthroughs, and supporting conversions. It is a niche but useful chemistry support component.

INTEG1 is the specialized integration reference. It is a deep anti-differentiation library with more than 33 formulas and procedures, including U-substitution, trig substitution, integration by parts with LIATE, repeated and cyclic parts, trig integrals, partial fractions, and applications like area between curves, volume methods, spring work, pumping fluids, center of mass, and pressure. It complements DERIV2 inside the calculus packages.

KEM1V6 is the main first-semester chemistry solver. It covers stoichiometry, molarity, percent composition, empirical and molecular formulas, gram-mole-molecule conversions, percent yield, thermochemistry, gas laws, solutions, dilutions, colligative properties, acids and bases, and a sizable reference-data section. This is one of the core chemistry files in the catalog and anchors the first-semester chemistry product.

KEM2V2B is the second-semester chemistry solver. It covers solutions, colligative properties, van't Hoff osmotic pressure work, Clausius-Clapeyron, kinetics, Arrhenius equations, half-life models, equilibrium, Kc/Kp conversions, ICE-table help, electrochemistry, Nernst and Faraday calculations, and nuclear chemistry. It is the advanced chemistry counterpart to KEM1V6.

LINEAR2 is the specialized linear-equation analyzer and converter. It accepts slope-intercept, point and slope, two points, or standard form, then returns slope-intercept and standard form, parallel slope, perpendicular slope, and intercepts, while also handling vertical and horizontal cases cleanly. It is a focused single-topic linear tool.

MECH1 is the first mechanics solver in the physics sequence. It covers kinematics, projectile motion, dynamics, circular motion, work and energy, and momentum. It is the first half of the AP Physics mechanics package and handles the topics students usually hit earliest in the course, making it one of the central physics solver files in the catalog.

MECH2B is the second mechanics solver and covers the later AP Physics mechanics topics. It includes springs and SHM, pendulums, rotational motion, angular momentum, rolling motion, orbital mechanics, and fluids. It is the follow-up to MECH1 and completes the broader mechanics coverage in the physics bundles.

PARA3 is the dedicated parabola analyzer for equations in standard form. It determines whether the parabola opens up or down, finds the vertex, max/min, axis of symmetry, y-intercept, and x-intercepts, while handling two real roots, one real root, or no real roots. It is a focused quadratic-analysis tool.

PERIOD4 is the periodic table reference component. It gives students on-calculator access to the elements and their core data without needing a printed periodic table nearby. Because chemistry and AP science bundles often benefit from quick access to atomic masses, symbols, and related reference information, this file appears in many science products as a supporting companion rather than a main solver.

POLPAR is the polar and parametric calculus component in the BC and STEM bundles. It fills the BC-specific gap around non-rectangular representations, especially for slope, area, arc length, and related parametric or polar relationships. It functions as a BC support reference alongside CALCEQ10 and SERIES8.

PRECAL is the precalculus formula/reference file. It serves as a fast formula bank for conics, logs and exponents, permutations and combinations, sequences and series, geometry, and trigonometry. It is not meant as a step-by-step solver but as a high-speed on-calculator formula sheet.

SAT9B is the full SAT-style practice solver that is not intended for test-day use. It covers systems, automated algebra solving, absolute value, function plug-in, linear-equation conversion, quadratics, circles, percents, statistics, exponential functions, and a large triangle section. This is the more aggressive homework and practice version of the SAT calculator program because it includes automated solving features that go beyond current SAT-compliant use.

SATSAFE is the SAT-compliant counterpart to SAT9B. It removes prohibited automated algebra-solving functions and replaces them with compliant logic and guidance while still covering systems, linear equations, quadratics, circles, percents, exponentials, statistics, and radical simplification. It is the test-day-safe version meant to align with current College Board calculator restrictions.

SEQNSER1 is the sequences and series solver for arithmetic and geometric models. It handles arithmetic sequences and series, geometric sequences and finite and infinite series, recursive patterns, and a reference library for common formulas. It is a strong Algebra 2 and precalculus support tool and also feeds into BC calculus readiness.

SERIES8 is the advanced BC series and Taylor polynomial reference. It includes the GPART convergence strategy, convergence-test selection logic, standard Taylor and Maclaurin series, radius and interval of convergence, and Lagrange error bounds. It is one of the most specialized AP Calculus BC components in the catalog.

STATEQ2 is the statistics formula and strategy reference. It covers descriptive statistics, probability, distributions, confidence intervals, sample-size formulas, test statistics, hypothesis testing logic, and test-selection guidance. It is a strong formula/reference component rather than a black-box statistics solver.

THERMO6 is the updated thermodynamics and thermochemistry solver component used across chemistry, physics, and larger science bundles. It helps students work through heat transfer, phase changes, internal energy, enthalpy, Gibbs free energy, equilibrium constants, Hess's Law, and common thermodynamics-related unit conversions on the TI-84 Plus CE.

The program includes sections for enthalpy, heat-transfer calculations, melting and vaporizing phase changes, complete ice-to-steam energy changes, custom phase-change problems, internal energy using dU = q + w, Gibbs free energy, spontaneity, standard free energy from enthalpy and entropy, equilibrium constants, van't Hoff-style temperature changes for K, STP reference information, Hess's Law examples, formation enthalpy references, and temperature, energy, volume, and pressure conversions.

THERMO6 includes an improved Gibbs/equilibrium section with clearer gas constant handling and more consistent unit guidance for students. In equilibrium-constant calculations, the program uses the standard value R = 8.314 J/(mol·K) where appropriate, helping students avoid common entry mistakes while keeping units consistent between kJ/mol and J/mol.

TRIGID2 is the trigonometric identity library. It is a deep-dive identity reference with more than 40 formulas, including Pythagorean identities, reciprocal and quotient identities, angle-sum formulas, double-angle and half-angle formulas, product-to-sum, sum-to-product, power reduction, cofunction identities, negative-angle rules, and the Laws of Sines and Cosines. It shows up often because it supports both precalculus and calculus bundles and also strengthens large AP science and STEM bundles where trig is frequently needed in the background.

TRISOLV3 is the triangle solver and reference suite. It handles right-triangle work, SOH-CAH-TOA, special right triangles, similarity and scale factor, triangle area, equilateral triangles, complementary-angle identities, and conceptual help. It appears both as a standalone triangle tool and as a support file in larger SAT and STEM bundles.

UNITCONJ is the broad, all-purpose unit conversion utility used across much of the catalog. It is designed to help students quickly convert common classroom and exam units without leaving the calculator workflow. Rather than focusing on just one subject, UNITCONJ supports a wide range of STEM use cases and works as a reusable support tool inside chemistry, physics, SAT math, and general math/science programs. It includes SI prefix tools, length, mass/weight, area, volume, speed/velocity, temperature, time, pressure, flow rate, angle conversion, rate conversions, decimal-to-fraction support, and basic distance-rate-time calculations. Because it covers so many common conversions in one place, UNITCONJ appears in more products than almost any other support component in the catalog.

VSEPR1 is a chemistry reference program for quickly reviewing electron geometry, molecular geometry, bond angles, hybridization, polarity, and example molecules on the TI-84 Plus CE. It covers common VSEPR cases from 2 domains through 6 domains, including linear, bent, trigonal planar, trigonal pyramidal, tetrahedral, trigonal bipyramidal, T-shaped, square pyramidal, square planar, and octahedral arrangements. It also includes a help section explaining VSEPR notation and common bond-angle patterns, making it useful for general chemistry, honors chemistry, AP Chemistry, and introductory college chemistry.

WAVES3 appears throughout the science bundles as a bonus or support component. Even where it is not the headline program, it adds extra value in bundles that touch spectroscopy, wave behavior, and related science topics. It functions as one of the recurring "support" files that broadens the usefulness of larger bundles.
