If e^y=tanx, 0 . integral Nov 26, 2006 · The two identities that are important for this equation are: (sin x)/(cos x) = tan x (sin x)^2 + (cos x)^2 = 1. I found it easiest to work on the right side of the equation, and figure it in terms of sin x. 1 + sinx = sin^2(x/2) +cos^2((x/2) + 2sin(x/2)*cos(x/2) ={sin(x/2) +cos(x/2)}^2 Similarly, 1-sinx = sin^2(x/2)+cos^2(x/2) - 2sin(x/2)*cos(x/2) ={sin(x/2)- cos(x/2)}^2 sinx sinxcos x sin x−= 23. sinx b. The sum would be cos2x+ 1− 2sinx +sin2x (1− sinx)cosx. = 2− 2sinx (1 −sinx)cosx. = 2 cosx. =2secx.

In this case, it's the left hand side (LHS).
