Unformatted text preview: 1. Find a linear differential operator L so that one solution of the differential equation Ly = 0 is: y(x) = 10xex + x3 ex  2 sin(3x)ex + 10 Solution: The differential operator (D  1)4 sends Ax3 ex + Bx2 ex + Cxex + D to zero. The differential operator ((D  1)2 + 32 ) sends A sin(3x)ex + B cos(3x)ex to zero. The differential operator D sends A to zero. So the composition of these three operators will send y to zero. L = (D  1)4 (D  1)2 + 32 D Ly = 0 1 ...
