Numeric Solver
655
Enter a number or expression for all variables except the one you want to solve for.
Notes and Common Errors
•
If you define a variable:
-
In terms of another variable in the
equation, that variable must be
defined first.
-
In terms of another variable that is not
in the equation, that variable must
already have a value; it cannot be
undefined.
-
As an expression, it is evaluated
when you move the cursor off the line.
The expression must evaluate to a
real number
•
If the equation contains a variable already
defined in terms of other variables, those
other variables are listed.
Note:
When you assign a value to a
variable in the Numeric Solver, that
variable is defined globally. It still exists
after you leave the solver.
Since a is defined in
terms of g, you must
define g before a.
When you move the
cursor to another line,
g/3 is evaluated.
If variable a was
defined previously as
b+c
!
a, then b and c
are listed instead of a.
