Question

Please help me simplify: cos^2 [(π/2)-x] /cos x.
It's supposed to become sin x tan x, but can someone explain how to do it using trig identities?
Thank you!

Answer 1

I think you have written the question incorrectly.
sin x tan x = sin^2 x / cos x,
which may help.

Answer 2

No, I didn't. Thanks for your help anyways.

Answer 3

Thank you!
