verify the identity. 1 - sin x / 1 + sin x = (sec x - tan x)^2 to verify the identity, start with the more complicated side and transform it to look like the other side. choose the correct transformations and tra expression at each step. (sec x - tan x)^2 = (1 / cos x - sin x / cos x)^2 rewrite in terms of sine and cosine inside parentheses. (do not simplify.) = □ (simplify your answer.)
Answer
Answer:
$\left(\frac{1 - \sin x}{\cos x}\right)^2$
Explanation:
Step1: Combine fractions in parentheses
$\left(\frac{1}{\cos x}-\frac{\sin x}{\cos x}\right)^2=\left(\frac{1 - \sin x}{\cos x}\right)^2$
