Find the Tangent Line Equation at Point (2,1)
In this tutorial students learn how to find the the equation of the line tangent to a function at the given point. This point is also known as the point of tangency. The students then verify the results using the TI-84C graphing calculator. The students will use the GRAPH, DRAW, TANGENT, WINDOW and Y= functionality from the calculator.
Substitute in the x value from the point of tangency (2,1)
