This interactive page allows readers to construct a Kuratowski 14-Set on the real line by selecting from among ten checkboxes, each representing a given set of real numbers.
Marden's Theorem concerns the relative positions of the roots of a cubic polynomial and those of its derivative. This article gives a proof of Marden's theorem, along with dynamic geometry animations and some of the history of the result.
This article explores the symmetry method in elementary differential equations, which uses the invariance of the equation under certain transformations to create a coordinate system in which the equation greatly simplifies.
