Question

I would really appreciate some help with this

Answer 1

le me solve ett plzz???lol

Answer 2

First use the sin^2 + cos^2 x = 1, and replace csc x with 1/sin x\[\Large \frac{ \cos^2 x }{ \frac{ \sin x }{ 1 } - \frac{ 1 }{ \sin x } }\]Now just add fractions in the denom, get common denom first

Answer 3

so it's (cos^2x)/((sin^2x-1)/sinx)?
