What is cot^2theta-sectheta in terms of sintheta?

1 Answer

((1-sin^2theta)/(sin^2theta))-((1)/sqrt(1-sin^2theta))

Explanation:

The identities used in this question are

1) cos^2theta+sin^2theta=1

2) cot^2theta=(cos^2theta)/(sin^2theta)

3) sectheta=1/costheta

So

=>cot^2theta-sec^2theta

=> (cos^2theta)/(sin^2theta)-1/costheta

=>(1-sin^2theta)/(sin^2theta)-(1)/sqrt(1-sin^2theta)
