Find cotangent of theta if cosecant of theta equals 8/3?

If you use the pythagorean identities, and say that cotangent ^2 = cosecant ^2 -1, how do you solve?

cottheta=sqrt55/3cotθ=553

Explanation:

.

cot^2theta=csc^2theta-1cot2θ=csc2θ1

cot^2theta=(8/3)^2-1=64/9-1=55/9cot2θ=(83)21=6491=559

cottheta=sqrt55/3cotθ=553
