Overlay of Graphs with Variation of a Function Parameter

  In some situations, it is useful to compare the behavior of a function as one of its parameters varies. The SimPlot program allows graphical visualization of overlaid profiles of an equation in which different values are assigned to a given parameter (“k”).


1 Usage and example

  To use SimPlot, the following elements must be placed on the stack prior to running the program:
# Input:
1. mathematical function;
2. minimum x-value of the function ("xi");
3. maximum x-value of the function ("xf");
4. list containing the values of the parameter "k" to be varied;

# Output:
1. animated plot of the equation with variation in "k";
2. function, values, and list remaining on the stack for further modifications.

# Example:
1. Select "exSim" to load the example list;
2. Press EVAL to unpack the list;
3. Run "SimPlot".
  The figures below illustrate the program using the provided example.
