1-sin² x (1-sin x)(1+cos x) the first step would be to: = 1+sin x 1+cos x 3. We are trying to prove that Starting on the left hand with Type in a, b, c, or d from the choices below a. change 1 - sin² x into cos²x b. cancel away a sin x from the sin² x on top and the sinx on the bottom c. factor 1 - sin² x in the numerator using a difference of squares d. multiply the together (1 - sin x) (1 + cos x) in the denominator
