ORDINARY 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
Differential equations of first order contain only first derivative of y, i.e., y . We We are going to discuss different types of first order equations in this section.
2 ordinary differential equations for engineers With the replacements of the variables y,y ′ ,···,y ( n ) in 1.1 by the functions ϕ ( x ) ,ϕ ′ ( x ) ,···,ϕ ( n ) ( x ), the EQ.
An equation involving derivatives of one or more dependent variables with respect to one or more independent variables is called a di erential equation. De nition. y(x) denote a function in the variable x. An ordinary erential equation (ODE) is an equation containing one or more derivatives of an unknown function y.
You will find in your other subjects that solutions to ordinary differential equations (ODE’s) are often written as definite integrals, rather than as indefinite integrals. This is particularly true when initial conditions are given, i.e., an initial-value problem (IVP) is being solved.

Ordinary Differential Equations An ordinary differential equation (or ODE) is an equation involving derivatives of an unknown quantity with respect to a single variable.
Differential equations are called partial differential equations (pde) or or- dinary differential equations (ode) according to whether or not they contain partial derivatives.
