How to solve summation equations

WebThis calculus video tutorial provides a basic introduction into summation formulas and sigma notation. It explains how to find the sum using summation formulas for constants, i, i^2, and i^3.... WebA summation has 4 key parts: the upper bound (the highest value the index variable will reach), index variable (variable that will change in each term of the summation), the lower bound (lowest value of the index value - the one it starts at), and an expression.
