Question

Verify the identity.

4 csc 2x = 2 csc^2x tan x

Answer 1

sin ( 2x) = 2 sin (x) cos (x)

Answer 2

csc (x) = 1/ sin (x)

Answer 3

Where did the 4 go?

Answer 4

it turned into a 2

Answer 5

\[4 \csc(2x) = \frac{4}{\sin(2x)}\]

Answer 6

Oh okay

Answer 7

do you know how to solve it now or do i need to walk you through it?

Answer 8

I understand now. It's a double angle identity

Answer 9

ok
