Simplify and write the trigonometric expression in terms of sine and cosine: ? So I came up with this = 1/f(u) But I am not sure what to do or if I am right?

I believe what you being asked to do is: Where the "?" is, combine terms, and you will get the desired form.
Can you explain what cofunction identities are?
Basically, if you have two complementary angles and , i.e.: then a trig. function whose argument is one of the angles will be equal to its co-function evaluated at the other. That is:

Yes, that would be the numerator...what is the common denominator, which is what f(u) is?

When you combine the two terms, the numerator simplifies to 1, but there is also the denominator.
I really don't know I am now lost.. I understand what you said, I just can't wrap my mind around this one...

common denominator is
