Browsing in the Equation Library

When you select a subject and title in the Equation Library, you

specify a set of one or more equations. You can get the following

information about the equation set from the Equation Library

catalogs;

■ The equations themselves and the number of equations.

■ The variables used and their units—you can also change the units.

■ A picture of the physical system (for most equation sets).

Viewing Equations

All equations have a display form—some equations also have a

calculation form. The display form gives the equation in its basic

form—the form you’d see in books. The calculation form includes

computational refinements. If the equation has a calculation form, an

* appears in the upper-left corner of the equation display.
