Understanding Derivatives with a Graphing Calculator

This video tutorial explains how to determine the value of a derivative function at a given point using a graphing calculator. It covers two methods: using the home screen and the Y equals function. The tutorial demonstrates evaluating derivatives at specific points and interpreting the results, including understanding the slope of the tangent line. The video also highlights the differences between the original function and its derivative, emphasizing the power rule for differentiation.
