Question: tan x+ sec x csc x = cot x Choose the correct proof below. OA. tan x+ sec X CSC X sin x 1
tan x+ sec x csc x = cot x Choose the correct proof below. OA. tan x+ sec X CSC X sin x 1 1 = + COS X sin x COS X sin x cos x 2 1-sin x sin x cos x 2 cos x = cot x OC. tan x+ sec xcsc x sin x COS X sin x cos x 2 1- sin x sin x cos x cos 2x cot x OB. O D. tan x+ sec x csc x sin x COS X 1 1 + COS X sin x X 1 - sin 2 sin x cos x 2 COS X sin x cos x = cot x tan x + sec xcsc x sin x COS X 1- sin 2 x sin x cos x 2 COS X sin x cos x = cot x
