Well, I think you could solve this using calculus pretty easily. Just take the derivative of 3cosx which equals -3sinx, then set that equal to zero to find the critical points, (where the slope equals 0) these will be your max and min values. -3sinx=0 @ -2π,-π, 0, π, and 2π. You can figure this out using the unit circle. (google it if you don't know) Oh, and the max and min values will be -3 and +3 depending on whether or not it is max or min. from -2π to 2π, it will be max, min, max, min, max
definite regardless of the incontrovertible fact that it wasn't purely a i did no longer learn I could cram form of factor i might learn plenty till now yet I even have constantly had an excellent form of difficulty drowsing and stress made it even worse so i might basically use that element to learn because of fact i could no longer sleep in any respect earlier assessments. Then i might get domicile after the examination and crash after which initiate analyzing for the subsequent one, once I week of doing this I very virtually fell asleep strolling and fell and took out the whole lag of my pajama bottoms and the floor on my knee good circumstances.

In that interval the cosine goes from -1 to 1,
but we have a coefficient of 3* cos x
so
-3 to 3
