The Bungee Jumper: a simple mathematical model

Exploring the energy transfers as a bungee jumper falls by considering each of the three stores (kinetic, gravitational and elastic) as a function of x and then summing.

Transversals in Triangles

Simple properties of medians, central verticals, angle bisectors and heights are shown.The idea is to show that it is not self-evident, that transversal lines in a triangle intersect in one…
