Verify the following identity:

_______________. =cosx

secx

or

2 sine squared x plus cosine 2 x divided by secant x

Can anyone do this problem for me and go over the steps...I've been going at it for a while and can't solve this ish.......I've used so many reciprocal identities and pythagreon identites and I still can't figure it out.

Thanks!
