Example on finding the sum of the infinite series x^n where |x| < 1 by noticing it is a convergent geometric series.

Example on converting a number with repeating digits into a fraction of integers via the geometric series.

Two examples on identifying geometric series and finding their sums, if the series converges.

In this video I go over the sum of an infinite series that involves taking multiple derivatives of the Geometric Series. Starting off with the Geometric Series for x^n, we can apply the derivative to it

In this video I demonstrate to you how to add up every number from 1 to 100 using a simple mathematical method developed by Carl Friedrich Gauss (1777-1855) when he was in Junior School. This video contains
