Hello all.

I'm loking for the conversion formulas to convert Rectangular coordinates to/from hyperbolic polar coordinates. Could you provide these formulas?


To convert (x,y) in rectangular to (u,v) in hyperbolic, let u = -(1/2) ln (y/x) and let v = sqrt(x*y) . Is that what you are looking for?

Hello there

I'm sorry. If you've seen the book, 'Everything You've Always Wanted To Know About RPN…,” there is a sample of Rectangular->Hyperbolic Polar Coordinate conversion. This and the Hyperbolic Polar->Rectangular conversion are the formulas I'm looking for.
