The given family of functions is the general solution of the differential equation on the indicated interval. Find a member of the family that is a solution of the initial-value problem. y=c1+c2cosx+c3sinx,(−[infinity],[in finity]) y=c 1 +c 2 cosx+c 3 sinx,(−[infinity],[infinity])
y'''+y′=0,y(π)=0,y′(π)=2,y''(π)=−1 y +y =0,y(π)=0,y ′ (π)=2,y ′′ (π)=−1
