Archimedes used the sum of a geometric series to compute the area enclosed by a parabola and a straight line. His method was to dissect the area into an infinite number of triangles. Archimedes' Theorem states that the total area under the parabola is 4/3 of the area of the blue triangle.

WebbCalculus Problem Solving &gt;. Put simply, the sum of a series is the total the list of numbers, or terms in the series, add up to. If the sum of a series exists, it will be a single number (or fraction), like 0, ½, or 99. The problem of how to find the sum of a series has been around since ancient times. WebbConsider a sum of terms each of which is a successively higher power of a number or an algebraic quantity represented by a variable: 1+ x + x2 +...+ xn. Note that the first term, that is "1", is also a power, namelyx0, and of course the expression x can also be written x1. So the geometric series can also be written x0 +x1 + x2 +...+ xn.

WebbSo the majority of that video is the explanation of how the formula is derived. But this is the formula, explained: Sₙ = a (1-rⁿ)/1-r. Sₙ = The sum of the geometric series. (If the n confuses you, it's simply for notation. You don't have to plug anything in, it's just to show and provide emphasis of the series.
