Hi, I am getting stuck on this one problem, I have my trigonometric identities down, but I can't figure out how to solve this problem:
The question asks:
"Simplify the trigonometric expression. Once you have simplified the expression completely, change all trigonometric functions in the simplified expression to sines and cosines. Finally, let s = sin(x) and c = cos(x) and enter your answer below. For example, if the expression simplifies to tan(x), you would enter s/c in the answer blank. (Note that your answer should use lower-case letters.)"
I'd really appreciate it if anyone could help, thank you very much in advance.
