**1. I have a circle equation**

[tex](x+a)^2+(y+b)^2=r^2[/tex]

And suppose we start from the topmost of the circle

**2.I have an angle Theta**

and if Theta is larger than 0 we move counterclockwise or we will move in the opposite direction if it is positive.

, how can I find out the coordinates of a point on the circle after the move

Thanks a lot :)
