Quadrilaterals, quadrangles and n-gons | Arithmetic + Geometry Math Foundations 45 | N J Wildberger
Precise definitions are important! Especially in geometry, where traditional texts too often just assume that the meanings of the main terms are obvious. Quadrilaterals, quadrangles and n-gons are good examples. This video belongs to Wildberger's MathFoundations series, which sets out a c

This is a video I have been wanting to make for some time, in which I discuss what the quaternions are, as mathematical objects, and how we do calculations with them. In particular, we will see how the fundamental equation of the quaternions i^2=j^2=k^2=ijk=-1 easily generates the rule for

Approximating Pi with Gregory's Theorem (visual proof for Pi day)
This is an animated visual proof of the Gregory's theorem, which provides a recursive method of finding the areas of the circumscribed 2n-gon and inscribed 2n-gon of a circle given the areas of the inscribed and circumscribed n-gons. As a Pi day treat, we show how to use these formulas to

What is the formula for a unit vector from a vector in component form
http://www.freemathvideos.com In this video series I will show you how to find the unit vector when given a vector in component form and as a linear combination. A unit vector is simply a vector with the same direction but with a magnitude of 1 and an initial point at the origin. It is i

Quaternions as 4x4 Matrices - Connections to Linear Algebra
In math, it's usually possible to view an object or concept from many different (but equivalent) angles. In this video, we will see that the quaternions may be viewed as 4x4 real-valued matrices of a special form. What is interesting here is that if you know how to multiply matrices, you a
