This may be somewhat of a basic question, but I need to know... I'm trying to find the minimum and maximum for the following: $y = \frac{\cos 3x}{5}+\sin 3x$
How is this done on a TI-83?

You try to sketch the graph and adjust the window so that it shows the minimum or maximum that you want to find. (Hint: try for example $x_{min} = -5$, $x_{max} = 5$, $y_{min} = -2$, $y_{max} = 2$)
You click [2nd] [calc] and choose (say) minimum.
You put the cursor to the left of the minimum and click enter. You put it to the right and click enter.
You move the cursor so that it is close to where the minimum is and you click enter.
Note i your case, you will have infinitely many maximums and minimums since he function is periodic. When you find say a minimum, then you can add any (integer) multiple of $\frac{2\pi}{3}$ to get the other minimums. This should be clear from the graph.
