# Determine Order and Degree(If Defined) of Differential Equation (D^4y)/(Dx^4) + Sin(Y^M) = 0 - Mathematics

Determine order and degree(if defined) of differential equation (d^4y)/(dx^4) + sin(y^("')) = 0

#### Solution

(d^4y)/(dx^4) + sin(y^(′′′)) = 0

=> y^(′′′) + sin(y^(′′′)) = 0

The highest order derivative present in the differential equation is y^(′′′) . Therefore, its order is four.

The given differential equation is not a polynomial equation in its derivatives. Hence, its degree is not defined.

Is there an error in this question or solution?
