Learn about trigonometry by playing a game!

This game is an arcade style game with increasing difficulty. Given the co-ordinates (x,y) of an asteroid, you need to calculate the corresponding angle (by solving a tangent equation) to shoot it.

At the start, the on-board computer does all the maths for you, but as you progress through the levels, the computer develops errors, and you need to do some (eventually all) of the maths yourself.
