Directions: Enter the coefficients of the differential
equation and the
parameters and type of the forcing function. Then click on "Draw" to
see the solution. You can also click on the graph to see the solution
through the point that you click on. You can select what the derivative
is at 0 if the coefficient in front of y'' is nonzero. Otherwise it will
given to you. The solution is carried out to two decimal places.
You can also set the window and zoom in and out. zStd will set the
-10 < x < 10, -10 < y < 10
After clicking on zIn or zOut click on the point in the xy-plane that
you want the center to be. This app works best using the Chrome
Instructional Video on this App:
1. Determine the relationship between a second order linear
differential equation, the graphicalsolution, and the analytic solution.
2. Explore how a forcing function affects the graph and solution of a
3. Realize that the solution of a differential equation can be written as
the sum of the homogeneous solution and the particular solution.
