WebUse Reduction Formulas to Simplify an Expression. The double-angle formulas can be used to derive the reduction formulas, which are formulas we can use to reduce the power of a given expression involving even powers of sine or cosine.They allow us to rewrite the even powers of sine or cosine in terms of the first power of cosine. Web• Tangent: tan 2x = 2 tan x/1- tan2 x = 2 cot x/ cot2 x -1 = 2/cot x – tan x . tangent double-angle identity can be accomplished by applying the same . methods, instead use the sum identity for tangent, first. • Note: sin 2x ≠ 2 sin x; cos 2x ≠ 2 cos x; tan 2x ≠ 2 tan x . by Shavana Gonzalez
