We solve it when we discover the function y (or set of functions y). Initial value of y, i.e., y(0) Thus we are given below. An ordinary differential equation (ODE) is an equation that involves some ordinary derivatives (as opposed to partial derivatives) of a function. The task is to find value of unknown function y at a given point x. The term ordinary is used in contrast with the term partial differential equation which may be with respect to more than one independent variable.

To some extent, we are living in a dynamic system, the weather outside of the window changes from dawn to dusk, the metabolism occurs in our body is also a dynamic system because thousands of reactions and molecules got synthesized and degraded as time goes. A partial differential equation (or briefly a PDE) is a mathematical equation that involves two or more independent variables, an unknown function (dependent on those variables), and partial derivatives of the unknown function with respect to the independent variables.The order of a partial differential equation is the order of the highest derivative involved. (The Mathe- matica function NDSolve, on the other hand, is a general numerical differential equation solver.) Degree of Differential Equation. The degree of the differential equation is the power of the highest order derivative, where the original equation is represented in the form of a polynomial equation in derivatives such as y’,y”, y”’, and so on.. A general first-order differential equation is given by the expression: dy/dx + Py = Q where y is a function and dy/dx is a derivative. Initial conditions are also supported. A linear equation or polynomial, with one or more terms, consisting of the derivatives of the dependent variable with respect to one or more independent variables is known as a linear differential equation. The Runge-Kutta method finds approximate value of y for a given x. Partial Differential Equation - Notes 1. An ordinary differential equation that defines value of dy/dx in the form x and y. An ordinary differential equation (ODE) is an equation that involves some ordinary derivatives (as opposed to partial derivatives) of a function. Suppose (d 2 y/dx 2)+ 2 (dy/dx)+y = 0 is a differential equation, so the degree of this equation here is 1. An ordinary differential equation (ODE) is an equation containing an unknown function of one real or complex variable x, its derivatives, and some given functions of x.The unknown function is generally represented by a variable (often denoted y), which, therefore, depends on x.Thus x is often called the independent variable of the equation.
