Cool calculus links.

This website out of the University of Tennessee, Knoxville, provides examples of using derivative shortcuts as well as A LOT of practice problems on using derivative shortcuts. Answers are provided. This is a great resource as you prepare to take the Derivative Gateway Exam.

This Desmos animation shows how the average velocities of a ball over a shrinking interval in time approach the instantaneous velocity of the ball at a specific moment. Another way to say it is that it shows how the slope of secant lines converge to the slope of a tangent line. The example comes from Section 1.1 of our text.

Awesome applet that both visualizes and computes Riemann Sums.
