Programming an arcade drive for joysicks

Y values:
Up is -1
Down is 1

X values:
Left is -1
Right is 1

i know there is something to do with triangles, but i'm not quite sure. Any help / links are really appreciated, thanks!

You don't need to invent your own algorithm (unless you want to).

The Java WPILib already has a ready-made Arcade Drive object.

It's in the file "RobotDrive.java"
