Nonlinear partial differential equations and their applications

For math, science, nutrition, history Differential Equations. The Wolfram Language can find solutions to ordinary, partial and delay differential equations (ODEs, PDEs and DDEs). DSolveValue takes a differential equation and returns the general solution: (C stands for a constant of integration.) A differential equation is an equation that involves the derivatives of a function as well as the function itself. If partial derivatives are involved, the equation is called a partial differential equation; if only ordinary derivatives are present, the equation is called an ordinary differential equation. Differential equations play an extremely important and useful role in applied math Wolfram|Alpha brings expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. Find differential equations satisfied by a given function: differential equations sin 2x differential equations J_2(x) Automatically selecting between hundreds of powerful and in many cases original algorithms, the Wolfram Language provides both numerical and symbolic solving of differential equations (ODEs, PDEs, DAEs, DDEs,). With equations conveniently specified symbolically, the Wolfram Language uses both its rich set of special functions and its unique symbolic interpolating functions to represent The Wolfram Language 's differential equation solving functions can be applied to many different classes of differential equations, automatically selecting the appropriate algorithms without needing preprocessing by the user. One such class is partial differential equations (PDEs). finds a numerical solution to the ordinary differential equations eqns for the function u with the independent variable x in the range x min to x max. NDSolve [ eqns, u, { x, x min, x max }, { y, y min, y max }] solves the partial differential equations eqns over a rectangular region. NDSolve [ eqns, u, { x, y } ∈Ω] Instructor Farid Pasha provides all the instruction you need to solve Differential equations using The Wolfram Language (Mathematica).Ordinary Differential E Work with Differential Equations.
