SOLVER
Type: Command
Description: Displays a menu of commands used in solving equations.
Access: …µ
SOLVER
Flags: If the CHOOSE boxes flag is clear (flag –117 clear), displays the operations as a numbered list. If
the flag is set, displays the operations as a menu of function keys.
Input/Output: None
SOLVEVX
Type: Command
Description: Finds zeros of an expression with respect to the current variable, or solves an equation with
respect to the current variable. (You use the CAS modes input form to set the current variable.)
Access: Symbolic solve, !Î, P
SOLVE
Input: An expression or equation in the current variable. A list of equations and expressions can be given
too, each will be solved for the current variable.
Output: A zero or solution, or a list of zeros or solutions.
Flags: Radians mode must be set (flag –17 set).
For a symbolic result, clear the CAS modes numeric option (flag –3 clear).
If Exact mode is set (flag –105 clear) and there are no exact solutions, the command returns a null
list even when there are approximate solutions.
If complex mode is set (flag –103 set) then SOLVE will search for complex roots as well as real
ones. Complex roots are displayed according to the coordinate system selected.
Example: Solve the following expression for 0, where X is the default variable on the calculator:
x
3
x– 9–
Command:
SOLVEVX(X^3-X-9)
Result:
X=2.24004098747
Note that if exact mode is set, this example returns a null list as there are no exact solutions to the
equation.

SORT
Type: Command
Description: Ascending Order Sort Command: Sorts the elements in a list in ascending order.
The elements in the list can be real numbers, strings, lists, names, binary integers, or unit objects.
However, all elements in the list must all be of the same type. Strings and names are sorted by
character code number. Lists of lists are sorted by the first element in each list.
To sort in reverse order, use SORT REVLIST.
