# Thread: Can anyone help me with the following?

2. ## Re: Can anyone help me with the following?

Suggest that you start by converting the tan, cot and sec functions to their sine and cosine equivalents. Then simplify, and look for an opportunity to apply one (or more) of the common trig identities, such as cos(a+b). You should ultimately get to a point where you have an equation of the form cos(A) = sin(B), from which you know that A = 90-B. Try it, and post back with your attempt at solving this..

Is this correct??

Do you know how to check solutions using a grapher?
