A differential equation solver is an online tool that aids in the calculation of differential equations. It provides numerical coordinates for the curves of the solution and may have a grapher for the function.
A typical solver provides the option to enter a single second order differential equation, such as x'' = f(x', x, t), and another option for a system of first order differential equations, such as x' = f(x, y, t), y' = g(x, y, t). A user may enter minimum and maximum graph settings for the graph solution.
A differential equation, which relates a function of one or several variables with its derivatives, is applied in fields such as engineering and physics.
