Introduction to Advanced Numerical Differential Equation Solving in Mathematica Overview The Mathematica function NDSolve is a general numerical differential equation solver. It can handle a wide range of ordinary differential equations (ODEs) as well as some partial differential equations (PDEs). In a system of ordinary differential equations there can be any number of

Plot the Results of NDSolve. NDSolve solves a differential equation numerically. It returns solutions in a form that can be readily used in many different ways. One typical use would be to produce a plot of the solution. As an example, take the equation with the initial conditions and : Copy to clipboard.

Although sometimes Mathematica is able to solve a differential equation, in practice we tend to rely on numerical methods to solve differential equations. Most differential equations that are found in actual practice are much too complicated to express a solution using elementary or special functions.

NDSolve[eqns, u, {x, xmin, xmax}] finds a numerical solution to the ordinary differential equations eqns for the function u with the independent variable x in the range xmin to xmax. NDSolve[eqns, u, {x, xmin, xmax}, {y, ymin, ymax}] solves the partial differential equations eqns over a rectangular region. NDSolve[eqns, u, {x, y} \[Element] \[CapitalOmega]] solves the partial differential ...

NSolve[expr, vars] attempts to find numerical approximations to the solutions of the system expr of equations or inequalities for the variables vars. NSolve[expr, vars, Reals] finds solutions over the domain of real numbers.

You can do arithmetic with the Wolfram Language just as you would on an electronic calculator. Arithmetic operations in the Wolfram Language are grouped according to the standard mathematical conventions. As usual, 2^3+4, for example, means (2^3)+4, and not 2^(3+4). You can always control grouping by explicitly using parentheses. With the Wolfram Language, you …
