number 36 please

is a particular solution of (6.42). PROBLEMS, SECTION 6 In Problem 33 to 38, solve the given differential equations by perposition see the solution of equation (6.29)]. For example, differential equations with right-hand sides equal to the three d terms with the same exponential factor are kept together; thus is kept together in one bracket. 33. y" + y = [x3 - 1] + [2 cos x] + [(2 - 4x) e"'] 34. y" - 5y + 6y =2ex + 6x-5 35.
