The "area" of a parabolic arc: a most important integral calculus computation, goes back to Archimedes.
Our new video on Signed Areas of Triangles on Curves for the Algebraic Calculus One course is now up.
Plimpton 322 has missing rows and columns, revealed by understanding how the tablet was made.
The highly over-rated radian angle measurement system is imposed on high school students unnecessarily!
What is the true role of the circular functions cos x and sin x etc?
Daniel and I believe that Plimpton 322 was not only the world's first trigonometry table, but also the only exact one!
To understand the meaning of Plimpton 322, we investigate ancient geometry in Egypt and Babylonia.
Check out the second lecture in the Algebraic Calculus One course: on vectors, displacements and centre of mass.

My new channel Wild Egg Mathematics Courses starts off with a Triangle Geometry playlist.
A different kind of video: a simple screenshot demo of the Binomial Distribution
The true laws of trigonometry are simple, elegant, and rational!
We can do planar metrical geometry with an arbitrary bilinear form. A very general geometry!

What is the geometrical meaning of a relativistic spread --replacing the notion of angle?
Chromogeometry reveals a remarkable three-fold symmetry in planar geometry!
The rational trigonometry notion of spread can be defined in the blue, red and green geometries.
