Viviani's theorem basically states that the sum off lengths of 3 lines, drawn at 90 degrees from the sides of an equilateral triangle to any inner point is always equal to the height.

saw this theorem online and thought that I would program a nice and simple…

I will show you how to derive the vertex formula of a parabola. That is, the vertex of a parabola y=ax^2+bx+c is at x=-b/(2a). I will use the algebra way, completing the square, and the calculus way, taking the derivative & critical number, to prove the formula.…

The answer is: a lot of them! In this video, I show that F(R), the set of functions from R to R, has the same cardinality as P(R), the set of subsets of the real numbers, which, in a previous video, I’ve shown to be much bigger than R. This is set theory…
