Investment returns from a 100% mortgage are compared against those from renting and saving. The comparison assumes the use of equivalent capital in each case and shows the effects of interest rate and inflation scenarios. In this Demonstration, the prop...

The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily.
Two polygons of the same area are said to be equivalent. In [1], Tarski defines the degree of equivalence of two equivalent polygons V and W as the smallest natural number n for which there exists a dissection of V to W using n pieces. The function is d...

An epitrochogon is the trace (roulette) of a point attached to a polygon rolling without slipping around the outside of another polygon [1]. The epitrochogon can be curtate if the tracing point is inside the rolling polygon, or prolate if it is outside....
