Prove the given identity. cot x + sec x csc x= tan x www 1 sin x Choose the correct proof below. OA. - cot x+ sec x csc x =- = = COS X sin x 2 1 1 cos x sin x 1- cos x sin x cos X 2 sin X sin x cos x = tan x O C. - == cot x+ sec x csc x COS X sin x sin x cos x 1 - cos 2 X sin x cos x 2 sin X = tan x O B. O D. cot x+ sec xcsc x COS X == = 1 sin x COS X sin x cos x 2 1 - cos X sin x cos x 2 sin X = tan x - cot x+ sec xcsc x COS X = sin x 2 1- cos x = sin x cos X 2 sin X sin x cos x = tan x
