Entering and Evaluating Equations
6-13
Example:
Evaluating an Equation with XEQ.
Use the results from the previous example to find out how much the volume of the
pipe changes if the diameter is changed to 35.5 millimeters.
The value of the equation is the old volume (from
V) minus
the new volume
(calculated using the new
D
value) — so the old volume is smaller by the amount
shown.
Responding to Equation Prompts
When you evaluate an equation, you're prompted for a value for each variable
that's needed. The prompt gives the variable name and its current value, such as
. If the unnamed indirect variable (I) or (J) is in an equation, you will not
be prompted to for its value, as the current value stored in the unnamed indirect
variable will be used automatically. (See chapter 14)
To leave the number unchanged,
