I still don't know your question. If you're trying to find , then the answer would be , because in the cartesian plane, with point (x, y) on the terminal ray, .

First, watch your notation. You can't write a trig function without an angle. YouI know sin=3 and cos=-2 but that is it.mustwrite something like

or .

Second, neither value is possible. Sine or cosine of any angle will be between -1 and 1 inclusive. If you're using the point (x, y) to figure out sine and cosine, you need these definitions:

and

.

In other words, you forgot to divide each by r. (r is easy to find, it's just ).

Please clarify your question(s).
