The Total solution for NCERT class 6-12
The numbers of arbitrary constants in the general solutionof a differential equation of fourth order are:
(A) 0 (B) 2 (C) 3 (D) 4
We know that the number of constants in thegeneral 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 differentialequation is four.
Hence, the correct answer is D.
