Question

Simplify the expression.
cosine x ^2 + sinx ^ 2 / cot x ^ 2 - csc x ^2

Answer 1

\[\cos ^{2}x + \sin ^{2}x = 1 \]

and \[\cot ^{2} x= \frac{ \cos ^{2} x }{ \sin ^{2}x }\]

and \[\csc ^{2}x = \frac{ 1 }{ six ^{2}x }\]

knowing this can you simplify the expression?

Answer 2

Yeah for the bottom part of it would I just cross multiply

Answer 3

not cross multiply just use some algebra and substitution.

Answer 4

is it not that cot^2 - csc ^2 =-1? therefore it is = -1?
