In Problems 1–12, a differential equation is given along with the field or problem area in which it arises. Classify each as an ordinary differential equation (ODE) or a partial differential equation (PDE), give the order, and indicate the independent and dependent variables. If the equation is an ordinary differential equation, indicate whether the equation is linear or nonlinear.
(aerodynamics, stress analysis)
Step 1 of 6</p>
In this problem, we have to determine the type of a differential equation, its order, independent and dependent variables and also whether it is linear or non linear.
Step 2 of 6</p>
Given Differential equation
d2y/dx2) + (dy/dx) + xy = 0
Step 3 of 6</p>
It is an ordinary differential equation, because it has only 2 variables x and y
