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.
