In each of Problems 1 through 4, determine "(xo), " (xo), and (4)(xo) for the given point to if y = o(x) is a solution of the given initial value problem. 1. y + xy + y = 0; y(0) = 1, 2. y + (sin x)y' + (cosx)y = 0; 3. xy" + (1+x)y' + 3(lnx)y = 0; 4. y"+xy + (sin x)y = 0; y(0) y'(0) = 0 y(0) = 0, y'(0) = 1 y(1)=2, y(1) = 0 ao, y(0) = a
