Calculating Slope of Tangent Line Using the Definition of a Derivative

Watch this video on limits as the slopes of tangent lines.

Before you watch, know that, for this problem, the limit that gives the slope of the tangent line to a curve is y = f(x) at a point x = a , which is the derivative of f(x) at a . We will talk about this more in Unit 3.
