Document Summary

Provide a generalization to each of the key terms listed in this section. In order to avoid errors when it comes to using a graphing calculator, you must [and can] store unrounded values in memory for the usage in subsequent calculations. A + b = 90 x2 + y2 = r2 a2 + b2 = c2 r2 + y2 r2 = r2 x2 r2 c2 + b2 a2 c2 = c2 c2 r (cid:1)2 (cid:0) x. = 1 sin2 ( ) + cos2 ( ) = 1. Whenever you let theta, which is , be an acute angle of any right triangle, which will explain the following functions: Tangent sin = opposite hypotenuse cos = adjacent hypotenuse y r x r b c a c tan = opposite adjacent y x b a. Theorem csc = hypotenuse opposite sec = hypotenuse adjacent r y r x c b c a cot = adjacent opposite x y a b.
