Question

Find the order and derivative of the D.E's

Question = d⁴y/dx⁴ + sin(y¹¹¹) = 0

Answer 1

Hello,

d⁴y/dx⁴ + sin(y¹¹¹) = 0

In the given question; highest order derivative is 4.

so, order is 4.

Now given differential equation includes trigonometric function along with third derivative of y.

so degree is not defined for such equations.

So, Order is 4 and degree is not defined.

Hope it helps you
