Let f(x)=cos x. Determine the x-value(s) where the function has a maximum or minimum value on [0,2π).

To enter π, type Pi (with a capital P)

The fields below accept a list of numbers or formulas separated by semicolons (e.g. 2;4;6 or x+1;x−1). The order of the lists do not matter.

On [0,2π), the maximum value(s) of the function occur(s) at what x-value(s)?

On [0,2π), the minimum value(s) of the function occur(s) at what x-value(s)?
