Integrating with the TI-84

This video tutorial demonstrates how to find a definite integral on the TI-84 calculator using two methods. The first method involves using the integral template, while the second method uses graph mode. The tutorial provides step-by-step instructions for both methods, including entering functions and setting limits. It also highlights the benefits of visualizing the area under the curve when using graph mode.
