Exclamation Trigonometric Identities (Pre-Calculus) - April 5th 2010, 07:21 PM

Got some problems that I don't know how to do.

Sec x - (1/sec x) = ?


I know you have to convert the Sec x to (1/cos x), but that's as far as I got. Can you please tell me how to do it?

Another problem is:

sec^4 x + sec^2 x tan^2 x - 2 tan^4 x = ?

I have a math test tomorrow. Would greatly appreciate responses.

Oh my goodness. I don't miss this.
I'll go see if I can find my notebook and get back to you.


There is always hope. PM me anytime.

I hope you did well on your test Brandon. I'm going to close this now since your test is over. Feel free to PM me if you would like it reopened
