 Hi and welcome to the session. Let us discuss the following question. Question says determine order and degree of following differential equations. Given equation is y dash plus pi y is equal to 0. Let us now start with the solution. Now first of all, we will rewrite the differential equation given in the question. Now we know order of a differential equation is the order of the highest order derivative occurring in the differential equation. Now the highest order derivative in the given differential equation is y dash. So order of this differential equation is 1. Now let us discuss about degree of this differential equation. Now we know degree of a differential equation is defined if it is a polynomial equation in its derivatives. Now clearly we can see given differential equation is a polynomial equation in pi dash. Highest power raised to dy upon dx is 1. So its degree is 1. Now this is our required answer. This completes the session. Hope you understood the solution. Take care and have a nice day.
