Calculus & Beyond

Derivatives

Inverse Functions and Their Derivatives This is a nice demonstration of the graphical relationship between f and its inverse, as well as the slope of the derivative of the inverse. Created by Dave Cesa.
Mean Value Theorem A nice interactive visual for the Mean Value Theorem and locating the "c" value(s). Created by Dave Cesa.

Integrals

Reimann Sums Lots of options and customizability. Created by Dave Cesa.
Simpson's Rule Lots of options and customizability. Created by Dave Cesa.

Sequences and Series

Sequence Definition This is a demonstration I made regarding a specific sequence and it's limit to illustrate the definition of the limit of a sequence.
Geometric Sequence and Series Let's you modify both a and r to investigate both the terms of the geometric sequence and the partial sums of the series.
Sum of (1/2)^n This is a fun visual demonstrating the sum of (1/2)^n.
Integral Test 1 This one demonstrates the Integral Test for the series 1/n^2.
Integral Test 2 This demonstrates the Integral Test for the series 1/n.
Taylor Series I modified another calculator I found to show the Taylor series of degree n, with a slider for n and a slider for the center.
