The degree of the differential equation is represented by the power of the highest order derivative in the given differential equation. The differential equation must be a polynomial equation in derivatives for the degree to be defined. Example 1:- $$\frac{d^4 y}{dx^4} + (\frac{d^2 y}{dx^2})^2 – 3\frac{dy}{dx} + y = 9$$ Here, the exponent of the highest order derivative is one and the given differential equation is a polynomial equation in derivatives. Hence, the degree of this equation is 1.

The linear equation (1.9) is called homogeneous linear PDE, while the equation Lu= g(x;y) (1.11) is called inhomogeneous linear equation. Notice that if uh is a solution to the homogeneous equation (1.9), and upis a particular solution to the inhomogeneous equation (1.11), then uh+upis also a solution to the inhomogeneous equation (1.11). Indeed
Simply put, a differential equation is said to be separable if the variables can be separated. That is, a separable equation is one that can be written in the form. Once this is done, all that is needed to solve the equation is to integrate both sides. The method for solving separable equations can therefore be summarized as follows: Separate the variables and integrate.
