SOLVEVX
Description: Finds zeros of an expression with respect to the cun-ent
variable, or solves an equation with respect to the
ciuxent variable. (You use the CAS modes input fonn to
set the ciuTent variable.)
Access: Symbolic solve, 0{Ssj3
Input: A fmiction or equation in tire current variable.
Output: A list of zeros or solutions.
Flags: For a symbolic result, clear the CAS modes Numeric
option (flag -03 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.
Example: Solve the following expression for 0, where X is the
default variable on tlie calculator:
Type: Command
Command: SOLVEVX (X"3-X-9)
Result: {X=2.2400}
Note that if exact mode is set, this example returns a
null list as there are no exact solutions to the equation.
