Question

The order of the following differential equation `(d^3y)/(dx^3) + x((dy)/(dx))^5 = 4 log ((d^4y)/(dx^4))` is ______.

Options

• not defined

• 3

• 4

• 5

Answer 1

The order of the following differential equation `(d^3y)/(dx^3) + x((dy)/(dx))^5 = 4 log ((d^4y)/(dx^4))` is 4.

Explanation:

The order of a differential equation is the highest derivative that appears in the equation. 

The highest derivative is `(d^4y)/(dx^4)`

The order of the differential equation is 4.
