The degree of the differential equation ...

The degree of the differential equation
`(d^(2)y)/(dx^(2))+3((dy)/(dx))^(2)=x^(2)log((d^(2)y)/(dx^(2))),` is

A

1

B

2

C

3

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
D
Since the equation is not a polynomial in all differential coefficients. So, its degree is not defined.
