Question

Anybody help me prove this identity step-by-step, reason-by-reason please? Will give medal and fan.

Prove the identity by simplifying both sides of the equation. (sin^2 x) * (csc^2 x) = sin^2 x + cos^2 x

Answer 1

idk

Answer 2

You could have just not answered then? lol

Answer 3

I will give you medal if you give me one?

Answer 4

No thanks lol I seriously need help with this problem, I'm not tryina play games right now.

Answer 5

I just wanted a medal but I will give you one because I am nice bye bye

Answer 6

Alright, thanks.

Answer 7

Actually, start with the LHS:

\((\sin^2x)(\csc^2x)\)

Convert \(\csc^2x\) to \(\dfrac{1}{\sin^2x}\):

\((\sin^2x)\left(\dfrac{1}{\sin^2x}\right)\)

Answer 8

Notice that \(1 = \sin^2x + \cos^2x\):

\(\dfrac{\sin^2x}{\sin^2x}(\sin^2x + \cos^2x)\)

And \(\dfrac{\sin^2x}{\sin^2x}\) cancels leaving just:

\(\sin^2x + \cos^2x\)
