AVS Axer :
Exp(x) and atan2(a,b) are already known, alpha is well known, pi is already a basic knowledge.
Oh, and your code is wrong (I didn't test, so not 100% sure).
1. T is never 8, so there is never any increase of t or s, so the counter won't work.
2. The x will just draw across the screen, so the correction should be x=s/8t+1;
