sin cos using SUB SumLocate (x,y,l)

[pmackay]

hey guys. i want to locate a location on using sin,cos....

I am not good a math.

i want it to give me the cords of a given center x,y (center of circle) with location as 360deg from center as in l = 360d input at x,y


so lets say x=200, y=200,l=90 so it returns x,y position - 50pixel from center to l degrees of circle

: x      =  150    
:
O-----------y    =  150

if any one can help thank you...

i need to be able to pick a number from the circle at any one time and have an x,y location.   i send x,y,d and it returns x,y from center of x,y circle minus distance in deg.....

hope i said it clear... almost confused myself
