Answer 1

Answer:

Step-by-step explanation:For Example (i): \frac{d^3 x}{dx^3} + 3x\frac{dy}{dx} = e^y

In this equation the order of the highest derivative is 3 hence this is a third order differential equation.

Example (ii) : – (\frac{d^2 y}{dx^2})^ 4 + \frac{dy}{dx}= 3

This equation represents a second order differential equation.

This way we can have higher order differential equations i.e. n^{th} order differential equations.
