Six Ways to Sum A Series
Imagine taking a square and dividing it along the diagonal. Now take one section and divide that down the diagonal. Repeat this process into infinity. This is a simple example of summing of an infinite series. Although this example provides and easily determined sum of the infinite series, the... | {} |
