Lesson Summary:
In this lesson on derivatives, the concept of formal limits is introduced in order to find the slope of the tangent line. The formula for finding the slope is broken down to show that the derivative is the slope of the tangent line, and the formal definition is given. The presenter works through a simple example to demonstrate how the formula can be used to find the slope of a tangent line.
Lesson Description:
More explanation of derivatives and discussion of formal limits as they pertain to slope.
