b) Method of Undetermined coefficient
c) Variation of Parameter
d) All of the above​

Answer 1

Step-by-step explanation:

Shortcut Method

Answer 2

Answer:

Option C is right

Step-by-step explanation:

Concept

• Variation of Parameters is a method for producing a particular solution to an nonhomogeneous

Consider the given differential equation

y" + a​​​​​​2​​​​​y = tan(ax)

This is non homogeneous second order ordinary differential equation with constant coefficients.

Here g(x) = tan(ax)

The method variation of parameters can be used to solve the given differential equation
