Y = C1 cos 2x + c2 sin 2x is a two-parameter family of solutions of the second-order DE y'" + 4y = 0. If possible, find a solution of the differential equation that satisfies the given side conditions. The conditions specified at two different points are called boundary conditions. 0, y(T) 0 40. y(0) 39. y(0) 0, y(T/4) 3 42. y(0) = 1, y'(m) - 41. y'(0) 0, y'(7/6) 0 44. y'(T/2) 1, y'(m) = 0 43. y(0) 0, y(T) = 2
