Defining the Derivative at a Point

Symmetric Difference Quotient
Applying a Limit
What happens to the graphs of the secant lines and the values of the difference quotient and symmetric difference quotient as we let h approach 0?
Approximating the Derivative
Making a Better Approximation
How do we make an approximation of the derivative better?
Which is better at Approximating the Derivative
For the same value of h, which is typically a better approximation of the derivative, the difference quotient or symmetric difference quotient.
