Answer (1 of 6) Verify the following identity sin(x)^2 cos(x)^2 tan(x)^2 = 1/cos(x)^2 Hint Eliminate the denominator on the right hand side Multiply both sides by cos(x)^2 cos(x)^2 (cos(x)^2 sin(x)^2 tan(x)^2) = ^?1 Hint Express the left hand side in terms of sine and cosinAnswer (1 of 5) Sin 2x = 2 sinx cosx Cos2x = 2 cos^2 x 1 So, (sin 2x)/(1cos 2x) = 2 sin x cos x /(1 2 cos^2 x 1) = 2 sin x cos x /2 cos^2 x = sin x /cos x = tan x For the second part,we have tanx = sin 2x/(1cos2x) Put x = 675° tan 675° = sin 135°/ 1 cos 135° Now sin 135° =Tan 2x ≠ 2 tan x
