Max Value
Hi,

I'm having a bit of trouble with this question. And need some help getting started:

Given the function: y = 6cos(2pie/14)x - 2

- Determine the maximum value of this function.
- determine an expression for the x-values for which this maximum occurs.

Any help is much appreciated!

Thanks!

Jim.

max value of $\cos(something) = 1$ , where $(something)$ is an even multiple of $\pi$.
