TI-89 Calculator Functions and Series

This tutorial demonstrates how to use the TI-89 calculator to compute partial sums using sigma notation. It provides two examples: one involving a polynomial expression and another using factorials. The tutorial also explains how to use the sequence function to view individual terms of the sum. The video concludes with a summary of the methods discussed.
