Yesterday, I loaded a package so that I could plot a direction field of a differential equation. It worked just fine. The problem is that now that I want to do it again, it won't work! Using the same Mathematica Notebook, I tried the following:(adsbygoogle = window.adsbygoogle || []).push({});

1. LOAD THE PACKAGE AGAIN

<<Graphics`PlotField`

2. ENTER THE COMMAND AGAIN

PlotVectorField[{1, 9.8-v/5}, {t, 0, 10}, {v, 40, 60}, ScaleFunction->(1&), Axes->True, AspectRatio->1, AxesLabel->{"t", "v"}]

As soon as I enter the command, the output is not a plot, it is the command itself!!! I also checked out the help section, but I couldn't find anything for this particular problem.

Any help is highly appreciated.
