Title: Math question
Post by: Rayquarian on April 07, 2009, 03:56:49 PM
If 1/cos x = sec x, does 1/cos^2 x = sec^2 x?

No homework help threads.

But I'll leave this open til you get an answer. But then >:(

And, I don't think so. It was on my formula sheet though...so yeah.

sec^2 x
sec x times sec x
1/cos x times 1/cos x
1/cos^2 x

So yes.

Yes, because 1 squared is still 1.

So yes.
The man sounds smart. Locked.
