How to go about making tankDrive and ArcadeDrive methods

For example, i was trying to figure out how i would get the left motors to stay off and the right motors to stay full on when the joystick is at teh top left corner(X,Y) = (-1,1), and see if that code works for all quadrants. I used y+X for the left wheels and Math.max(X,Y) for the right wheels. However that algorithim doesnt work for all four quadrants so Ive made a big branching if-else so I have a different algorithim for each quadrant of the cartesian plane and another if else for if the joystick is on the x or y axis.
It looks pretty inefficient but without trig i dont think theres another way to do it.
