I'm not sure to have well understood what's your problem in what you say,
but the polar coordinates of a point in a plane are
x = radius*cos(angle)
y = radius*sin(angle)
where angle is the angle beetwin the x-axis and the line from the origin and
your point, and radius, the distance from the origin to the origin
hoping it'll help you in any way
