Find the order and degree (if defined) of the equation: `(d^4y)/(dx^4)-sin((d^3y)/(dx^3))=0`

Answer

Order-4, degree not defined

Explanation

`(d^(4)y)/(dx^(4))-sin(d^(3)y)/(dx^(3))=0`
The highest-order derivative present in the differential equation is `(d^(4)y)/(dx^(4))`. Thus, its order is four.
However, the given diifferential equation is not a polynomial equation, Hence, its degree is not defined.
