Simplifying summation notation
WebbS = Sum from k to n of i, write this sum in two ways, add the equations, and finally divide both sides by 2. We have S = k + (k+1) + ... + (n-1) + n S = n + (n-1) + ... + (k+1) + k. When we add these equations, we get 2S on the left side, and n-k+1 column sums that are each … Summation notation (or sigma notation) allows us to write a long sum in a single … To represent your example in summation notation, we can use i*(-1)^(i+1) where … WebbIt is called Sigma Notation (called Sigma) means "sum up" And below and above it are shown the starting and ending values: It says "Sum up n where n goes from 1 to 4. ...
