cSolve()

You should also use
var
_ for any other
variables in
Equation
that might have
unreal values. Otherwise, you may receive
unexpected results.
cSolve(
Eqn1
and
Eqn2
[

,
VarOrGuess1
,

[

)
⇒
Boolean expression
cSolve(

)
⇒
Boolean expression
Returns candidate complex solutions to the
simultaneous algebraic equations, where
each
varOrGuess
specifies a variable that
you want to solve for.
Optionally, you can specify an initial guess
for a variable. Each
varOrGuess
must have
the form:
variable
– or –
variable
=
real or non-real number
For example, x is valid and so is x=3+
i
.
If all of the equations are polynomials and
if you do NOT specify any initial guesses,
cSolve()
uses the lexical
Gröbner/Buchberger elimination method to
attempt to determine
all
complex solutions.
Note:
The following examples use an
underscore (press
/_
) so that the
variables will be treated as complex.
Complex solutions can include both real and
non-real solutions, as in the example to the
right.

Simultaneous polynomial equations can
have extra variables that have no values,
but represent given numeric values that
could be substituted later.
