(a) Write a general expression for yp(x) a particular
solution to the nonhomogeneous
differential equation [Do not evaluate the coefficients]
y′′ + 2y′ + 2y = e-x (4x + sin x) + 2 cos(2x).
(b) Solve the initial value problem
y′′ - y = 1 + 4ex; y(0) = 1; y′(0) = 2:
Consider the following differential equation:
x2y"-2xy'+(x2+2)y=0
Given that y1=x cos x is a solution, find a second
linearly independent solution to the differential equation.
Write the general solution.
