The no. of arbitrary constant in the general solution of a differential equation of 3rd order is

Answer»

ANSWER:

The number of arbitrary constants in the general solution of a differential equation is 3

Step-by-step explanation:

In this question,

Let y''' = 1

On INTEGRATING we get,

y'' = X + A                        where A is the constant

Now , again Integrating we get,

y' = \frac{x^{2}}{2}\ +\ A\ +\ B              where A and B are constant.

Integrating again,

y = \frac{x^{3}}{6}\ +\ A\ +\ B\ +\ C         Where A, B, and C are constants

Therefore, Number of Constants = 3

HENCE, Number of arbitrary constants in a general solution of a differential equation is 3
