I have a Cartesian coordinate system that is rotated and translated relative to another Cartesian coordinate system. I would like to be able to take any (x,y) in the first system and calculate the equivalent (x,y) in the second one. The coordinate systems have the same units and scale, so only a translation and rotation is applied.

This should just be 'simple' trigonometry, but I can't seem to get anything to work.

Any suggestions?

Thanks,

Gerald
