Verify that the equation is an identity. csc x - sin x = cos x cot x . . . . . To verify the identity, start with the more complicated side and transform it to look like the other side. Choose the correct transformations and transform the expression at each step. csc x - sin x= - sin x Use a common denominator to perform the subtraction. Separate the expression into two factors. = cos x cot xUse trigonometric identities to write cos x in terms of sin x. Choose the correct expression equal to cos x. O A. COSX= 1 - sin x O B. cosx = + V1 - sin 2x O C. cosx= 1 11 - sinx O D. cosx = (1 - sin x)(1 + sin x)
