Click OK to load the functional scalar into the top register.

Vector

A vector function, in which the values of the vector's x-, y-, and z-components are given by functions.

To enter a functional vector:

Click Function.
The Function dialog box appears.
Select Vector.
Select the function from the list.
For each component of the vector, click SetX, SetY, and SetZ.
Click OK to load the functional vector into the top register.

The predefined variables X, Y, and Z; RHO, THETA, R, and PHI; and any functions that you created can be used to define functional scalar and vector quantities.

Use of the Global Coordinate System is assumed. Local coordinate systems are not used.
