Question

Prove the identity:
secx+cosx/secx-cosx = 1+cos^2x/sin^2x

Answer 1

Have you tried converting them into sin and cos?

Answer 2

\(\LARGE \frac{1}{cosx}+\frac{cosx}{1}*\frac{cosx}{1} -cosx =1+\frac{cos^2x}{sin^2x} \)

Answer 3

Thank you for your help apparently the program we have to use for school did not like the way I was simplifying the fraction. I just wanted to make sure I was doing it correctly.
