for positive n.
In essence this means you take the range of cos(x) and raise both sides to the exponent n. Be wary of even exponents and negative numbers
For example, what is the range of f(x) = cos^3 x? ...cos^2 x?
I understand the range of cosx and sinx but I'm not sure how to adjust for the exponents. I think there must be something simple that I'm just missing, so if someone could explain, that would be great.
Thanks.
