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!

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 .
