The Sum of Squares Calculator is used to calculate the sum of first n squares or the sum of consecutive square numbers from n12 to n22.
The sum of the first n square numbers is equal to:
n(n + 1)(2n + 1) / 6
The sum of consecutive square numbers from n12 to n22 is equal to:
n12 + (n1 + 1)2 + ... + n22 = n2(n2 + 1)(2n2 + 1) / 6 - n1(n1 - 1)(2n1 - 1) / 6
