Consider the differential equation: 66t^2y''+12t(t-11)y'-12(t-11)y=5t^3, . You can verify that y1 = 5t and y2 = 4te^(-2t/11)satisfy the corresponding homogeneous equation.
The Wronskian W between y1 and y2 is W(t) = (-40/11)t^2e^((-2t)/11)
Apply variation of parameters to find a particular solution.
