solve()
Catalog >
false is returned when no real solutions are
found. true is returned if solve() can
determine that any finite real value of Var
satisfies the equation or inequality.
Since solve() always returns a Boolean
result, you can use “and,” “or,” and “not” to
combine results from solve() with each
other or with other Boolean expressions.
Solutions might contain a unique new
undefined constant of the form nj with j
being an integer in the interval 1–255. Such
variables designate an arbitrary integer.
In Radian angle mode:
In Real mode, fractional powers having odd
denominators denote only the real branch.
Otherwise, multiple branched expressions
such as fractional powers, logarithms, and
inverse trigonometric functions denote only
the principal branch. Consequently, solve()
produces only solutions corresponding to
that one real or principal branch.
Note: See also cSolve(), cZeros(), nSolve(),
and zeros().
solve(Eqn1 and Eqn2[and …],
VarOrGuess1, VarOrGuess2[, …])
⇒ Booleanexpression
solve(SystemOfEqns, VarOrGuess1,
VarOrGuess2[, …])
⇒ Booleanexpression
solve({Eqn1, Eqn2 [,...]}
{VarOrGuess1,VarOrGuess2 [, … ]})
⇒ Booleanexpression
Returns candidate real solutions to the
simultaneous algebraic equations, where
each VarOrGuess specifies a variable that
you want to solve for.
