Section 2.5 Vectors

To add a vector to the plot, select the option Vector: <a, b, c> from the Add to graph menu. The following dialog will appear:

Vector object dialog
Figure 2.5.1 Vector object dialog

Enter the components of the vector, select a color and enter a positive width value for the vector. You can then also enter the coordinates of an initial point. By default, the initial point is assumed to be the origin.

To graph the vector, either press enter in one of the vector textboxes or check the checkbox in the upper lefthand corner of the vector object dialog.

Currently parameters are not yet allowed in vectors, although it is likely to be possible soon!
