Question

Simplify the expression.
cos^2(π/2−x)/√1−sin^2(x) =

Answer 1

write 1=sin^2 (x) +cos^2 (x)

so inside squareroot sin^2(x)-sin^2(x)=0 and will remained sqrt(cos^2(x))

then rationalize the denominator

hope this will help you like a first step

Answer 2

i still dont understand at all i dont know how or why u did that i thought u were supposed to square root it first
