This site features a collection of videos involving multiple topics in differential equations.
The applet draws solution curves (actually animates them) and direction fields for 2x2 autonomous systems.
Plots the solution curves of a user-input two dimensional system of autonomous differential equations. It has a reasonable parser, flexibility, and speed.
Video describing how to model and solve a problem involving the position of a mass attached to a srpring.
Notes explaining basic modeling with first order differential equations, looking at specific examples of Mixing Problems, Population Problems, and Falling Bodies.
These student Interdisciplinary Lively Applications Projects developed over seven years are collected at the COMAP website (Â
Graphs solutions of diffusion equations over time. Interface could be smoother. You have to click at different points on the timeline to get things graphed - animation would be helpful.
Eleven interactive activities from the definition to solutions of ODEs
Applet that shows the poles of the Laplace transform in the frequency domain and the graph of the solution in the time domain simultaneously.
Enter (constant) coefficients for a first order autonomous system.
