Hi, assuming you have x and want to generate y, then maybe - if x < 50, y = 150
- if x > 175, y = 60 - otherwise : either y = (100/(e^((x -50)/75)^2)) + 50 http://www.wolframalpha.com/input/?i=plot++%28100%2F%28e ^%28%28x+-50%29%2F75%29^2%29%29+%2B+50%2C+x%3D50..175 - or maybe y =sin((x+5)/38)*42+105 http://www.wolframalpha.com/input/?i=plot++sin%28%28x%2B5%29%2F38%29*42%2B105%2C+x%3D50..175 Regards, Kent Fitch On Tue, Feb 14, 2012 at 12:29 PM, Mark <static.void....@gmail.com> wrote: > I need some help with one of my boost functions.
