How do you find limits involving trigonometric functions and infinity?

Most of them don't exist. For example, all six standard trig functions don't have a limit since they oscillate into infinity. If you have some other function, they could have limit behavior (such as with #sinx/x to 0#) but that is generally due to other behaviors.

The best we can normally do is basically the limit max and min, or so-called sup and inf, respectively.
