Degree of a Differential Dquation

The order of a differential equation is the order of the highest order derivative present in the equation. dx )2 = y (dy)^2 / dx2 + ey has order 3. The degree of a differential equation is the power of the highest order derivative in the equation.

The differential equation must be a polynomial equation in derivatives for the degree to be defined.
Example 1:- d4ydx4+(d2ydx2)23dydx+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.
