WebIn this problem you will use variation of parameters to solve the nonhomogeneous equation t 2 y ′′ + 4 t y ′ + 2 y = 2 t 3 + 3 t 2 A. Plug y = t n into the associated homogeneous equation (with " 0 " instead of " 2 t 3 + 3 t 2"") to get an equation with only t and n. (Note: Do not cancel out the t, or webwork won't accept your answer!)
