Okay, so I have a programming assignment due tomorrow. It's pretty slick, I have a plane that flies around, you can shoot enemies that shoot back. The only source of navigation is an arrow that rotates about the plane, being given a number in radians to turn. So far, all of the algorithms I have used to convert the coordinates of the enemy into radians have failed. Below is a bad visual representation of what I need:




I have the Math class' Sin, Cos, Tan, Asin, Acos, Atan

Just a stupid question; can the plane only shoot from the front, or can it shoot in whatever directions, no matter which way it is facing?

Sorry to trouble you, got the answer after fiddling around, adding my time to this being about 2 hours to figure this out... Thanks for the quick response.

This may help in future - http://en.wikipedia.org/wiki/Polar_coordinates
