WEBA differential equation (de) is an equation involving a function and its deriva-tives. Differential equations are called partial differential equations (pde) or or-dinary differential equations (ode) according to whether or not they contain partial derivatives. The order of a differential equation is the highest order derivative occurring.
WEBshow particular techniques to solve particular types of rst order di erential equations. The techniques were developed in the eighteen and nineteen centuries and the equations include linear equations, separable equations, Euler homogeneous equations, and exact equations. Soon this way of studying di erential equations reached a dead end.

WEBReaders are familiar with solving algebraic equations. For example, the solu-tions to the quadratic equation x2 −x= 0 are easily found to be x= 0 and x= 1, which are numbers. An ordinary differ-ential equation, or just differential equation, is another type of equation where the unknown is not a number, but a function. We call the unknown ...
WEBAn ordinary differential equation (ODE) is an equation (or system of equations) written in terms of an unknown function and its derivatives with respect to a single independent variable (such as time). Examples include the familiar equations of classical mechanics and electrical circuits.
