sec(theta) = 1/costheta so, just multiply (1/costheta)*costetha = 1

I don't have a calc. I'm trying to learn how to do these without a calc and that is pretty much impossible. Sorry, jeez.

I will use latex to make it easy to see:\[\sec \theta = \frac{ 1 }{ \cos \theta }\]It's a rule. So,\[\sec \theta*\cos \theta=\frac{ 1 }{ \cos \theta } * \cos \theta = \frac{ \cos \theta }{ \cos \theta } = 1\]
