Products of Chords in a Circle (math visualization)

In this video, we describe a classic problem about finding the product of the lengths of the chords obtained by placing n equally spaced points on the unit circle and connecting one of the points to each of the others. The answer is surprising and one proof relies on a limiting argument u

Half Angle Tangent Formulas (visual proof; trigonometry)

This is a short, animated visual proof of the half angle formula for the tangent using Thales triangle theorem and similar triangles. This theorem gives two ways to compute the tangent of a half angle, like tan(t/2). #mathshorts #mathvideo #math #trigonometry #triangle #manim #animation #t

Law Of Cosines I (visual proof)

This is a short, animated visual proof of the Law of Cosines using Thales triangle theorem and the intersecting chord theorem. This theorem relates the side of a triangle with the other two sides and the angle between those two sides. #mathshorts #mathvideo #math #trigonometry #lawofcosine
