Cosx + SinxTanx = SecX

I have been looking at this for some time now and have no idea. I am more than likely doing something supid, but I just can't figure it out. Pre-Calculus by the way.

He said verify not solve idiot.


cos(x)+sin(x)tan(x) = sec (x)
(sinx)(sinx/cosx) + cos x
sin^2 x/cosx) + cos x
(sin^2 x + cos^2 x)/cos x
1/cos x
sec x
