Answer» Correct Answer - Option 4 : Not defined Concept: Order: The order of a differential equation is the order of the highest derivative appearing in it. Degree: The degree of a differential equation is the power of the highest derivative occurring in it, after the Equation has been expressed in a form free from radicals as far as the derivatives are concerned. Calculation: \(\dfrac{d^2y}{dx^2}+3\left(\dfrac{dy}{dx}\right)^2 =x^2 \log \left(\dfrac{d^2y}{dx^2}\right)\) For the given differential equation the highest order derivative is 2. The given differential equation is not a polynomial equation because it involved a logarithmic term in its derivatives hence its degree is not defined. |
