validate() private static method

Verify the input arguments are valid for correct use of the secant method If the tolerance is less than zero, an Exception will be thrown. If $p₀ = $p₁, then we cannot run our loop because the slope with be undefined, so we throw an Exception.

private static validate ( number $p₀, number $p₁, number $tol )
$p₀	number	First initial approximation
$p₁	number	Second initial approximation
$tol	number	Tolerance; How close to the actual solution we would like.

    private static function validate($p₀, $p₁, $tol)
    {
        Validation::tolerance($tol);
        Validation::interval($p₀, $p₁);
    }
