Question

Verify the identity.

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

Answer 1

\[4\csc^2x=2\csc^2x\tan x\]
Are you sure you're not missing anything?

Answer 2

Yeah thats it

Answer 3

It's not an identity.
\[4\csc^2x\not=2\csc^2x\tan x\]
because
\[2(2\csc^2x)\not=2\csc^2x\tan x \\
2\not=\tan x\]

Answer 4

Ok thanks again

Answer 5
