I need help solving 5 and 6 please

. Sections 5.4 5.5 and 9.3: Undetermine Coefficients for nonhomogenous equations. . The most critical step is to set Up correctly. Examples. 1. Find a particular solution for y" - 3y' + 2y = ex (3 - 4x) 2. Find a particular solution for y" - 4y' + 4y = e27 (1 - 3x + 6x2). 3. Find a particular solution for y" + y' = 6 cos(3x). 4. Find a particular solution for y" + 4y = 8 sin 2x. 5. Find a particular solution for y" - 3y' + 3y = 20e2 sin 2x. 6. Solve the initial value problem y" - 3y" + 2y' = 2r + 4, y(0) = 1, y'(0) = 0, y"(0) = 2, y'"(0) = 0. 7. Find a particular solution for y(4) - y = cos x. 8. Find a suitable form of yp by the method of undetermined coefficients for y(4) + 8y" + 16y = x sin 2x. (No need to calculate the coefficients.) 9. Find a suitable form of yp by the method of undetermined coefficients for y" + 4y" + 4y' = 3x + 2 + x sin 2x. (No need to calculate the coefficients.) .
