Question: Given t = tan 1/2x, prove that Hence solve the equation 2 sin x cos x = 1 (a) sin.x = (b) cos.x =

Given t = tan 1/2x, prove that

(a) sin.x = (b) cos.x = (c) tan x= 2t 1 + f2 1-1 1 + 1 2t 1-1

Hence solve the equation 2 sin x – cos x = 1

(a) sin.x = (b) cos.x = (c) tan x= 2t 1 + f2 1-1 1 + 1 2t 1-1
