Given:

The set of differential equations.

Objective:

State the method to solve each differential equation.

Points to Note:

The undetermined coefficient method is the method to find the particular solution for the non-homogeneous part of the ordinary differential equation with constant coefficient. For finding the coefficient, the initial conditions are required.

Direct integration is the method which is able to take integration without simplifying or rewriting the differential equation.

Both the methods doesn't involve solving the given differential equations.
