Question

The number of arbitrary constants in the general solution of a differential equation of fourth order is
(a) zero
(b) 2
(c) 3
(d) 4

Answer 1

We know that the number of constants in the general solution of a differential equation of order n is equal to its order. Therefore, the number of constants in the general equation of fourth order differential equation is four. Hence, (d) is the correct option.
