I need a function. I have 3 inputs, X,Y,and Z X can be between -1 and 1 When X=1 or X=-1, and Y=0, the output of the function should be 1 When X and Y are both positive or negative, the output should be negative, otherwise the output should be a positive number If Y decreases, the output should increase If Y increases, the output should decrease Z should allow me to adjust be the point at which the output should =0 when X is negative and Y is positive or vice versa. Basically, if X is negative and Y is positive, the output should increase as Y decreases and stop at 1 when Y=0. If X is positive and Y is negative, the output should increase as Y increases and stop at 1 when Y=0. When abs(Y)=Z, the output should be zero. Z can be any value between 1 and 10. It will be a slider which goes up in increments of .25 or .5. And Y is anywhere betweeen -135 and 135
