Plotting distribution functions

Version: 3.x - Scientific WorkPlace & Scientific Notebook

Problem

If you try to plot NormalDist(x) or any other distribution function, the program gives the message

Could not plot this expression!

Explanation

The program inserts the discont=true parameter into the plot statement that it sends to the Maple computational engine. However, the presence of the parameter prevents Maple from plotting certain expressions.

Solution

We expect this problem to be corrected soon. In the meantime, this workaround allows a plot of NormalDist(x):

  1. In mathematics, enter f(x)=NormalDist(x).
  2. From the Compute (or Maple ) menu, choose Define and then choose New Definition.
  3. Plot f:
    1. Start a new line.
    2. Toggle to mathematics and then enter f.
    3. From the Compute (or Maple ) menu, choose Plot 2D and then choose Rectangular.
