The Hidden Power in Pascal's Triangle

What makes Pascal's triangle so powerful? It has deep connections to the Binomial Theorem and the Central Limit Theorem. And hidden within it are the powers of 2, the Fibonacci sequence, and the fractal Sierpinski's Triangle! Let's explore these patterns and see why they show up in Pascal's Triangle.

Another great video. These are always so educational and zen. I love the lack of wild jump cuts or other things. You respect the viewer, much appreciated.

It arises pretty naturally. I discovered it before hearing about it in precalc, when learning about expanding powers of binomials. I worked the first several powers out by hand and looked for patterns. The descending/ascending powers thing leaps right out, but took a bit of staring to notice how the coefficients of lower powers add to the coefficients of higher powers. I pointed it out to my teacher and they were like, “that’s Pascal’s triangles!”

ty dr Sean you even helped me by answering my mail, i have suggestion that you should make linear algebra videos why determinant proprties works, why the area exists as such so called determinant operator, you know i mean like its kind way off for newcomer

Dr. Sean, could you explain calculus like you are explaining it to a middle schooler pls?

[MostInterestingChannel]

can you teach real analysis to a middle schooler?

It's pronouncing shi-erpiñski, like Fibonacci is pronouncing fee-baw-nachee not fibounaksi
