TIMESERS.8xp

Summary: Time series program; graphs approximate solutions for x and y given dx/dt and dy/dt. Graphical data only.

Set Up: The expression for dx/dt must be entered in Y2 and dy/dt entered in Y3. Set the WINDOW parameters as desired.

The program will have you specify the initial condition (x, y) and a step size (Δt). The approximate graphs for x vs t and y vs t will be drawn simultaneously. I like to compare the results of this program with those of the TRAJECT program; for example, use the results from one and have the class predict the other.
