Nonlinear Equations
Solve any equation on an interval and a system of two nonlinear equations.
What to solve:
Equation:
x
x fromto
Write with “=”: cos x = x, x^2 + y^2 = 25. Such equations are solved numerically, apart from polynomials and fractions.
This calculator solves any equation in x on an interval and a system of two nonlinear equations in x and y.
Polynomials and fractions are solved completely. Other equations are solved numerically, so the answer depends on the search region and does not guarantee that all roots are found.
Example. cos x = x has the root x ≈ 0.739085. The system x² + y² = 25, x + y = 7 has the solutions (3, 4) and (4, 3).
