Determine order and degree (if defined) of differential equations given

It is given that equation is

y”” + sin(y’’’) = 0

We can see that the highest order derivative present in the differential is y””.

Thus, its order is four. The given differential equation is not a polynomial equation in its derivative.

Therefore, its degree is not defined.
