How do we calculate the value of an infinite geometric series 1 + r + r² + r³ +...?
Here is a classic geometric proof! (reference; for more details see trapezoid supplement)
On the next page, we find the sum of a geometric series by the "repeating decimal method" you probably learned in high school.
