I have the following mapping on the complex plane: $$ z \mapsto \tau \mu z-1, $$ where $\mu$ is complex, $\tau$ is real number. I want to draw the image of left unit semidisk and play with $\tau$. ...
One can truncate all the vertices of a polygon at once with Truncate. I want to do exactly that -- but only on a single vertex. Is this possible with Mathematica 9? ...
Returning a non-degenerate list of triangles that (strictly) define the outer mesh of a 3-polytope using PolyhedronData?
I'm looking for a simple method of returning a list of triangles that strictly define the outer surface of a 3-polytope using PolyhedronData? For example: ...
