13.6 Sigma Notation

SUMMATION NOTATION Often we want to sum the terms in a sequence so summation notation is a short-hand way express this. This number tells us what integer to start subbing in to create the terms in a sequence This number tells us when to stop (the last integer to sub in). This is the formula to sub into This sign means to sum up each of the terms in the sequence

Summation Notation  Ex: Evaluate the following sum:  Sol:
