# Thread: Point Transformation

1. ## Point Transformation

Given a point on a circle P, the circle's radius, and the angle point P is to be transformed about, is there a way to calculate the translated point P'? Let's assume the circle is centered on (0,0) Thanks!

2. If you've studied polar coordinates, then this is easy. If not...

Have you studied trigonometry yet?

3. I have studied trig, I'm a college graduate with a BS in Computer Science, I've exhausted the extent of my current trig knowledge, I've gotta as far as knowing the length of the chord between P and P' but I have no way of knowing the angles of the right triangle created using the chord as a hypotenuse. Unless there is a way that I just don't remember?

I'll read into polar coordinates
