Using variation of parameters method to find particular solution d^2y/dx^2+y=tanx+3x-1

The corresponding homogeneous equation

has characteristic equation

which admits two roots, , so the characteristic solution is

So we know two fundamental solutions, and . These two solutions have Wronskian determinant

so they are linearly independent.

We use variation of parameters to find a particular solution , where
