Hi y'all, I have a question about finding the period of trig functions. How do i find the period for trig functions such as cos^2(x), cos^3(x), and so forth?
If anyone could explain this to me it would be much appreciated!

Maybe it helps already to spell out a general rule: for , the period of depends only on whether is even or odd. If is even, we have period , if it is odd, we have period .
Do you see why? and if you are taking an even power, then the "-" does not matter. If you are taking an odd power, then it does. Of course, sine and cosine themselves have period .
