उत्तर
Degree of differential equation:
The degree of a differential equation is the power of the highest order derivative occurring in a differential equation when it is written as a polynomial in differential coefficients.
example: \[\left( \frac{d^2 y}{d x^2} \right)^2 - 4\left( \frac{dy}{dx} \right) = 2y\]
the degree of the given differential equation is 2
