# Determine Order and Degree(If Defined) of Differential Equation Y′ + Y = Ex - Mathematics

Determine order and degree(if defined) of differential equation y′ + y = ex

#### Solution

y′ + y = ex

=>y' + y - e^x = 0

The highest order derivative present in the differential equation is y'. Therefore, its order is one.

The given differential equation is a polynomial equation in y' and the highest power raised to y' is one. Hence, its degree is one.

Is there an error in this question or solution?
