Please see the attachement.
If Angle AOB is 90 degree. and two points A (S,T) & B (-Root3,1) are on circle. Then find out the point S. Point O (0,0)
Can some one tell me way to solve this question?

There was also a great explanation of this problem by Brent Henderson with attachments, but I can't find it.
