 Hi and welcome to the session. Let us discuss the following question. Question says determine order and degree of the following differential equation. Given differential equation is y dash plus y is equal to e raised to the power a. Let us now start with the solution. Now we are given differential equation y dash plus y is equal to e raised to the power x. Now first of all we will find order of this differential equation. We know order of the differential equation is the order of the highest order derivatives occurring in the differential equation. Now in this equation highest order derivative is y dash or we can say it is dy upon dx. We know we denote dy upon dx by y dash. So order of this differential equation is 1. So we can write the highest order derivative present in the given differential equation is y dash. So its order is 1. Now let us discuss about degree of this differential equation. We know degree of the differential equation is defined only when it is a polynomial equation. Clearly we can see this is a polynomial equation in y dash and y. And we also know that degree of a differential equation is the highest power of the highest order derivative in it. Now in this equation this is the highest order derivative and power of this highest order derivative is equal to 1 here. So degree of this differential equation is 1. So we can write the given differential equation is a polynomial equation in y dash and y. Highest power raised to y dash is equal to 1 so its degree is 1. So we get order of the given differential equation is 1 and degree of the given differential equation is also equal to 1. This is our required answer. This completes the session. Hope you understood the solution. Take care and keep smiling.
