Class 12th RD Sharma - Volume 2 22. Differential Equations

Answer :

Let any differential equation of order 3 be

Here A is any constant.

Now, to know the number of arbitrary constants in the general solution we integrate both sides of equation (1)

Again integrating

Again integrating

is the general solution of the differential equation with 3 arbitrary constants C₁, C_2, C₃.

∴ There are 3 arbitrary constants in the general solution of the differential equation of order 3.
