Constructing bilinear transformations
( go to the article → )
The previous post was a visual introduction to bilinear transformations, a.k.a. Möbius transformations or fractional linear transformations. This post is a short follow-up focused more on calculation. A bilinear transformation f has the form where ad – bc ≠ 0. Inverse The inverse of f is given by The transformation f is defined everywhere except […] The post Constructing bilinear transformations first appeared on John D. Cook.
