SUMMARY

The discussion centers on an error encountered in Mathematica when attempting to plot the function xe^{-x}. The user received the error message "Plot::exclul: must be a list of equalities or real-valued functions" while using the command Plot[x*e^(-x), {x, 0, 5}]. A suggested solution is to replace 'e^(-x)' with 'Exp[-x]', which is the correct syntax for the exponential function in Mathematica. This adjustment resolves the plotting issue.

PREREQUISITES
  • Familiarity with Mathematica syntax and functions
  • Understanding of plotting functions in Mathematica

Homework Statement



I am trying to plot [tex]xe^{-x}[/tex] by using Plot[x*e^(-x), {x, 0, 5}] and it keeps telling me that

Plot::exclul: must be a list of equalities or real-valued functions.

So I tried

Plot[x*e^(-x), {x, 0, 5}, PlotRange -> {-10, 10}]

Still not working

Try using 'Exp[-x]' for the exponential rather than 'e^(-x)'.
