WebApr 6, 2024 · n ∑ i = 1 x2i = This expression instructs us to total up squared values of x, starting at x1 and ending with xn. n ∑ i = 1 x2 i = x2 1 + x2 2 + x2 3 + ….. +x2 n. ∑ y - The limits of the summation generally appear as i = 1 through n. The representation below and above the summation symbol is usually omitted. WebArchimedes was fascinated with calculating the areas of various shapes—in other words, the amount of space enclosed by the shape. He used a process that has come to be known as the method of exhaustion, which used smaller and smaller shapes, the areas of which could be calculated exactly, to fill an irregular region and thereby obtain closer and closer …
