Find a particular solution yp of the following
EQUATIONS using the Method of Undetermined Coefficients. Primes
denote the derivatives with respect to x.
y''-16y=cos h(4x)
y''+36y=12cos(6x)+18sin(6x)
y''+4y'+8y=325e2tcos(5t)
y(5)+6y(4)-y=12
y(5)+2y(3)+2y''=8x2-2

Use the method of undetermined coefficients to find the complete
solutions of the following differential equations.
d2y/dx2 − 3 dy/dx + 2y = 2x2 +
ex + 2xex + 4e3x .
Solve the following constant coefficient linear differential
equations using Laplace Transform (LT), Partial Fraction Expansion
(PFE), and Inverse Laplace Transform (ILT). You must check
answers in the t-domain using the initial conditions.
Note: Complex conjugate roots
y ̈ (t) + 6 ̇y (t) + 13y (t) = 2
use the initial conditions
y(0) = 3, ̇y(0) = 2.
Write the form of yp that is needed for method of undetermined
coefficients. Use the annihilator method with the lowest order
differential operator. DO NOT SOLVE for the coefficients. You must
show the corresponding homogeneous solution and the differential
operator you are applying to each side of the equation as part of
your answer.
a. y′′ + 6y′ + 9y = 4cos x
b. y′′ + 7y′ +10y = 2e^6x + 3cos(5x)
c. y′′ + 9y′ + 20y = 5xe^4x
