Question

Find the order and degree of the following differential equation:

`[ (d^3y)/dx^3 + x]^(3/2) = (d^2y)/dx^2`

Sum
Advertisements

Solution

`[ d^3y/dx^3 + x]^(3/2) = (d^2y)/dx^2`

Squaring on both sides, we get

`[(d^3y)/dx^3 + x]^3 = ((d^2y)/dx^2)^2`

By definition of order and degree,

Order : 3 ; Degree : 3
