Determine the order and degree (if defined) of the differential equation (ds/dt)4+ 3s(d2s/dt2) =0

order =1, degree=1 order =2, degree=1 order =2, degree=2 none of these

order =2, degree=1

The highest order derivative present in the equation is d2s/dt2. Therefore its order is 2. The given differential equation is  a polynomial equation in d2s/dt2 and ds/dt. The highest power raised to d2s/dt2  is 1. Hence, Its degree is 1.
