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.

sec^2 x
sec x times sec x
1/cos x times 1/cos x
1/cos^2 x
So yes.
The man sounds smart. Locked.
