Sigma notation explained
WebSigma (Summation) Notation. As mentioned, we will use shapes of known area to approximate the area of an irregular region bounded by curves. This process often requires adding up long strings of numbers. To make it easier to write down these lengthy sums, we look at some new notation here, called sigma notation (also known as summation … WebOct 3, 2024 · Math’s Sigma (Σ) Symbol. In mathematics, the sigma symbol, Σ, is used to indicate that a sequence of numbers is to be added up after operating on each number with a rule. For example, you might want to add up the numbers one through three after multiplying each by two. So, something like:
