Thanks to Josh for this problem! And thanks to Folke for emailing it to me! There are 7 doors in a line. A mouse starts in the middle at door 4. At doors 1 and 7 are cats. Every day the mouse moves one door left or right randomly, each direction with an equal…

In this video (another Peyam Classic), I present an unbelievable theorem with an unbelievable consequence. Namely, I use Parseval’s theorem (from Fourier analysis) to calculate the sum of 1/n^2

Enjoy!

Here's a video describing programming magic: Monte Carlo integration!

It's a super cool algorithm that is used all the time (in physics at least), so it was good to cover it here. We'll have more algorithms coming up, so be sure to check them out as they…

We will discuss a calculus proof that differentiability implies continuity! If a function is differentiable at some point a, then it is continuous at that point. It means differentiable functions have to be continuous! But the converse of this isn't always…

In this video I integrate e^(ax)cos(bx) without using integration by parts or complex analysis, but instead using pure linear algebra. This is probably not the most efficient method, but it provides an illustration of how linear algebra makes everything neater.…
