Converting polar coordinates to rectangular coordinates

Answer 1

Let the fixed distance be D, then X = D * cos(A) and Y = D * sin(A), where A is the angle.

Answer 2

t = angle
r = radius (fixed distance)

x = rcost
y = rsint

Answer 3

What PolyThinker said.

Also, if you need the distance from the origin, it's sqrt(x^2 + y^2).

Answer 4

If center-point (Xcp, Ycp) isn't the origin you also need to add it's coordinates to (X,Y) i.e. X = Xcp + D * cos(A) and Y = Ycp + D * sin(A)
