The Solution about First Order Differential Equation of Intergral Factor
Abstract:This thesis will start from the related concept of ordinary differential equations,in order to illustrate the concept of ordinary differential equations,and two basic methods for ordinary differential equations.It discusses the concept of integral factor,including the definition of integral factor and integral factor of nature.Then usi ng different classification methods,the original integral factor method based on the textbook, more detailed system to explore the method of solving relatively r regular.The observation method, formula method and grouping method.And it summarizes so as to solve the problem of solving a differential equation.
Key words:First order ordinary differential equations;The definition of integal factor;To solve the integral factor
