Crazy Marty Trigonometry

You want to find angle Theta, I help you find it, no matter where it is: vertex, angle of depression, angle of elevationÖ even if itís complementaryÖ or supplementary!

You want to find length of side of triangle, I help you, using sine, cosine, tangent. You can even use cosecant, secant, cotangent. Heck, we can even use inverse trig.

You need to prove trig identities, I can help you. You can prove anything that makes sense, and even some things that donít!

You want to graph trig function? I can do it free-hand, or using calculator. Even using phase shifts. No trig graph too tricky.

You think Iím crazy, you crazy. Only wanted Pepsi.
