Overview of Summation Formulas
Calculus: We review some basic summation formulas and rules for calculating Riemann sums. Over the range i from 1 to n, we state formulas for the sum of a constant r, i, i^2 and i^3. We review sigma notation and prove the rules for r, i and i^2. We also work out the special case of sum 1 to 4 of (i+1)^2 using our formulas.
