Mistakes by using the formulas given above in exactly the form that they are given. If you are going to try these problems before looking at the solutions, you can avoid common Most of the following problems are average. We will need the following well-known summation rules. You always increase by one at each successive step. The number on top of the summation sign tells you the last number to plug into the given expression. The "i=" part underneath the summation sign tells you which number to first plug into the given expression. If f( i) represents some expression (function) involving i, then Let's first briefly define summation notation. Summation notation is used to define the definite integral of a continuous function of one variable on a closed interval.
The following problems involve the algebra (manipulation) of summation notation.
