This 3D Trigonometry Game will only be fun if you happen to like this sort of thing. You'll also have to dig up your old high school trig class memories if you want to have any success solving it.

It's not difficult and is quite fun too.

When you hit the Set Goal button a point in space is randomly selected, and the point of the game is to arrive at this point by entering polar vectors. You could of course enter the vector shown after hitting the button and you would arrive at the point (try it). But this is too easy!

To make things more interesting the only rule of the game is to enter vectors which are parallel with the x, y, and z axes, and the only way to do this accurately is to get your calculator out and do the math. If you've got the Windows OS then there's a handy calculator there where you can copy and paste values to and from the game.

Good luck, and have fun.
