Having been given the perimeter and perpendicular of a right angled triangle, it is required to find the triangle.

The incircle O(r) of triangle ABC touches AB at D, BC at E and AC at F. Find r in terms of AD, BE and CF.

A collection of articles on mathematics in Europe from the twelfth to the fifteenth century.

Cantor's work on Fourier series provides historical motivation for the study of point-set topology.

Poster of Banneker, with a brief description of his life and work.

In many sources, we see that Tartaglia has the surname Fontana. According to the author of this article, the co-discoverer of the cubic formula did not ever use that name.

This is a page from a manuscript of the Algebra (Maqalah fi al-jabra wa-al muqabalah) of Omar Khayyam (1048-1131). This work is known for its solution of the various cases of the cubic equation by finding the intersections of appropriately chosen conic sections.

As is the case with a great deal of interesting mathematics, the conic sections are believed to have been discovered in an attempt to solve a problem, a problem which on the surface seems to have nothing to do with conic sections.
