solve: y''+8y'+7y=f(t), y(0)=y'(0)=0, expressing your answer in
terms of a convolution, using partial fractions for:
i)f(t)=e^t
ii)f(t)=t^1/2
iii) f(t)=2sin(2t)
y''+ 3y'+2y=e^t
y(0)=1
y'(0)=-6
Solve using Laplace transforms.
Then, solve using undetermined coefficients.
Then, solve using variation of parameters.
Consider the following signal
y(t)=e−5.3tu(t)∗e−8.1tu(t)
Using the multiplication-convolution duality of the CTFT, y(t)
can be expressed in the frequency domain as:
Y(jw)=1A+Bjw+Cw2.
Find the values of A, B and C.
Solve the following IVP specifically using the Laplace transform
method
(d^3)x/d(t^3)+x=e^(-t)u(t) f(0)=0 f'(0)=0
f''(0)=0
where u(t) is the Heaviside step function
