WebNov 16, 2024 · Performing an index shift is a fairly simple process to do. We’ll start by defining a new index, say i i, as follows, i =n −2 i = n − 2 Now, when n = 2 n = 2, we will get i = 0 i = 0. Notice as well that if n = ∞ n = ∞ then i = ∞−2 =∞ i = ∞ − 2 = ∞, so only the lower limit will change here. Next, we can solve this for n n to get, n =i +2 n = i + 2 WebHow to use the summation calculator Input the expression of the sum Input the upper and lower limits Provide the details of the variable used in the expression Generate the results by clicking on the "Calculate" button.
