Question

Sin theta (csc theta) - sin^2 theta = cos^2 theta

Answer 1

Both Cos^2(theta)

Explanation:

Your teacher would likely want you to refer to the Reciprocal Identities and Pythagorean Identities.

Convert csc(theta) to = 1/ sin(theta)

`sin(\alpha )*csc(\alpha ) - sin^2(\alpha )\\\\sin(\alpha )*(1)/(sin(\alpha )) - sin^2(\alpha )\\\\1-sin^2(\alpha )\\\\cos^2(\alpha )`
