math problem: transform polar co-ordinates wrt new origin

Richard Garrett's icon

Hi all,

This is more maths than Max, but I thought here would be a good place to ask.

If a point has co-ordinates (r, theta) with respect to one point in space, how do I work out its co-ordinates with respect to another, known, location?

It's a spacialisation thing.

TIA

That will do nicely, thank you.

(just couldn't get my brain around it)

Funny i thought about this problem a while yesterday and came to somewhat the same thought that it should be fairly easy when you are in the cartesian system. But i felt stupid telling you this, because i thought there must be some way to do it without the conversion.
Is there a way to do that?
