Question

The order of differential equation (d^3y/dx^3)^2 + y = 0 is
a) 1
b) 2
c) 3
d) 4
Please give me the answer as soon as possible. ​

Answer 1

Answer:

c) 3

Step-by-step explanation:

Given equation

($\frac{d^{3}y }{dx^{3} }$)² + y=0

Order of a differential equation is the highest derivative of a term in the equation.

As we can see the only derivative term in the equation is  $\frac{d^{3} y}{dx^{3} }$.

Hence it is the highest derivative term of the equation and thus the order is 3.
