I’m struggling, with the result of this limit. Especially cos(x)^3 . Can someone explain what does it mean? According to my professor, it means cos^3(x); she is basically saying that cos(x)^3 = cos^3(x). I don’t think that it’s correct assumption. Can someone explain conventions of using parentheses in this case? Thank you so much!!
NOTE: I know the calculus, I know how to use powered cos, sin etc. and I know that cos^3(x) is different from cos(x^3).
