sin2 x +cos2 x = 1 sec2 x = tan2 +1 csc2 x = cot2 +1 Half Angle Formulas sin2 x = 1 2 (1 cos2q) cos2 x = 1 2 (1 +cos2q) Double Angle Formula sin2x = 2sin x cos x These identities are far a from complete, but they will suffice for most of the problem that we will encounter. To illustrate this, we will present the common strategies for ... ................
