solve(Inequality, Var) ⇒ Boolean
expression
Returns candidate real solutions of an
equation or an inequality for Var. The goal
is to return candidates for all solutions.
However, there might be equations or
inequalities for which the number of
solutions is infinite.
Solution candidates might not be real finite
solutions for some combinations of values
for undefined variables.
For the Auto setting of the Auto or
Approximate mode, the goal is to produce
exact solutions when they are concise, and
supplemented by iterative searches with
approximate arithmetic when exact
solutions are impractical.
Due to default cancellation of the greatest
common divisor from the numerator and
denominator of ratios, solutions might be
solutions only in the limit from one or both
sides.
For inequalities of types ≥, ≤, <, or >,
explicit solutions are unlikely unless the
inequality is linear and contains only Var.
For the Exact mode, portions that cannot be
solved are returned as an implicit equation
or inequality.
Use the constraint (“|”) operator to restrict
the solution interval and/or other variables
that occur in the equation or inequality.
When you find a solution in one interval,
you can use the inequality operators to
exclude that interval from subsequent
searches.
