Question

what is csc^2x + csc^2x?

Answer 1

in terms of what?

Answer 2

Here's the whole problem: Prove that each equation is an identity. CSC^2x-COS^2x CSC^2X=1

Answer 3

You have the left hand side
=CSC^2x-COS^2xCSC^2X
=cosec^2(x)-cos^2(x)cosec^2(x)
=cosec^2(x)[1-cos^2(x)]
=cosec^2(x)sin^2(x)
=cosec^2(x)[1/cosec^2(x)]
=cosec^2(x)/cosec^2(x)
=1
=right hand side
hence proved the identity.
