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.

WEBORDINARY DIFFERENTIAL EQUATIONS GABRIEL NAGY Mathematics Department, Michigan State University, East Lansing, MI, 48824. AUGUST 16, 2015 Summary. This is an introduction to ordinary di erential equations. We describe the main ideas to solve certain di erential equations, like rst order scalar equations, second
WEBA complete survey course in differential equations for engineering and science can be constructed from the lectures and examples, by skipping the technical details supplied in the text.
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 ...
