4)Find the general solution of the following differential
equation.
y''+4y=tan(x) -pi
5)A mass of 100 grams stretches a spring 98 cm in equilibrium. A
dashpot attached to the spring supplies a damping force of 600
dynes for each cm/sec of speed. The mass is initially displaced 10
cm above the equilibrium point before the mass is attached, and
given a downward velocity of 1 m/sec. Find its displacement for
t>0.
find the general solution of the given differential
equation.
1. y'' + y = tan t, 0 < t < π/2
2. y'' + 4y' + 4y = t-2 e-2t , t >
0
find the solution of the given initial value problem.
3. y'' + y' − 2y = 2t, y(0) = 0, y'(0) = 1
