Write order and degree (if defined)of each of the following differential equations:


The order of a differential equation is the order of the highest derivative involved in the equation. So the order comes out to be 2 as we have and the degree is the highest power to which a derivative is raised. But here when we open the series of as . Also, the equation has to be polynomial. Therefore the degree is not defined. Also, the equation has to be a polynomial, but opening the exponential function will give undefined power to the highest derivative, so the degree of this function is not defined.

So the answer is 2, not defined .
