Spherical geometry | Differential geometry
In differential geometry, the tangent indicatrix of a closed space curve is a curve on the unit sphere intimately related to the curvature of the original curve. Let be a closed curve with nowhere-vanishing tangent vector . Then the tangent indicatrix of is the closed curve on the unit sphere given by . The total curvature of (the integral of curvature with respect to arc length along the curve) is equal to the arc length of . (Wikipedia).

Paraboloids and associated quadratic forms | Differential Geometry 23 | NJ Wildberger
Paraboloids are going to play a special role in our understanding of curvature. The idea is that we are going to locally approximate a surface S near a point by a normal paraboloid---one that shares the same tangent plane, but has an axis which is perpendicular to that tangent plane. It w

Tangent Tangent Angle Theorems - Circles & Arc Measures - Geometry
This geometry video tutorial provides a basic introduction into tangent tangent angle theorems as it relates to circles and arc measures. The sum of the minor arc and the tangent tangent angle is supplementary. The two angles add up to 180. This tutorial contains plenty of examples and

What is the difference between a secant and tangent line
Learn the essential definitions of the parts of a circle. A secant line to a circle is a line that crosses exactly two points on the circle while a tangent line to a circle is a line that touches exactly one point on the circle. A chord is a line that has its two endpoints on the circle.

The Tangent Line and the Derivative (Calculus)
In calculus, you’ll often hear “The derivative is the slope of the tangent line.” But what is a tangent line? The definition is trickier than you might think. Tangent lines are important because they are the best way to approximate a curve using a line. We can then use the slope of the

Meusnier, Monge and Dupin III | Differential Geometry 33 | NJ Wildberger
We look at some of the work of Charles Dupin, a French naval engineer and student of Monge. He made some lovely discoveries about triply orthogonal surfaces and lines of curvatures, for example confocal families of ellipses and hyperbolas. He studied conjugate directions on surfaces (going

We consider a simple population genetics model with recombination. We assume that at time 0, all individuals of a haploid population have their unique chromosome painted in a distinct color. At rare birth events, due to recombination (modeled as a single crossing-over), the chromosome of t
