Precalculus Equations & Formulas (TI-84 Plus CE)
📘 Conics, Logs, Sequences, Trig Laws & Identities — Always at Your Fingertips
Keep your most important precalculus formulas inside your calculator. This two-program reference bundle is built for Precalculus students — and many taking AP Precalculus — who want faster formula access without flipping through notes or textbooks. PRECAL covers the major formula categories; TRIGID2 adds 40+ trig identities as a dedicated quick-reference.
What's Included
| File Name | Type | What It Does |
|---|---|---|
| PRECAL | Reference Program | Precalculus formula reference organized in menus. Covers conic sections (circle, ellipse, hyperbola, parabola), logarithm and exponent rules, permutations and combinations, arithmetic and geometric sequences and series, basic algebra and geometry formulas, and trig laws (Law of Sines, Law of Cosines, area formulas). |
| TRIGID2 | Reference Program | 40+ trigonometric identities organized for quick calculator-based lookup. Covers Pythagorean identities, reciprocal and quotient identities, co-function identities, even/odd identities, sum and difference formulas, double-angle formulas, half-angle formulas, and product-to-sum identities. |
Coverage includes:
- ✅ Conic sections — circle, ellipse, hyperbola, parabola
- ✅ Logarithm and exponent rules
- ✅ Permutations and combinations
- ✅ Arithmetic and geometric sequences and series
- ✅ Basic algebra and geometry formulas
- ✅ Trig laws — Law of Sines, Law of Cosines, area
- ✅ 40+ trig identities (TRIGID2)
This is a reference program, not a solver — designed to reduce memorization, speed up review, and make it easier to find the right formula when working through homework, practice problems, and test prep. Best for: Precalculus students, students preparing for Calculus, and AP Precalculus students who want a cleaner formula system directly on their calculator.
