Compute the Laplace transform. Your answer should be a function of the variable \( s \) : \[ \mathcal{L}\left\{2+u_{3 / 2}(t) e^{2 t} \cos (\pi t)\right\}= \] \( \square \) You may find the following formulas useful: \[ \begin{aligned} \cos (b t+\pi) & =-\cos (b t) \\ \sin (b t+\pi) & =-\sin (b t) \\ \cos \left(b t+\frac{\pi}{2}\right) & =-\sin (b t) \\ \sin \left(b t+\frac{\pi}{2}\right) & =\cos (b t) \end{aligned} \]

Step 1
The given function is \( f(t) = 2 + u_{3/2}(t) e^{2t} \cos(\pi t) \), where \( u_{3/2}(t) \) is the unit step function that shifts the function by \( 3/2 \). Show more…

Compute the Laplace transform. Your answer should be a function of the variable s: L{4 + u_{5/2}(t)e^{-5t} sin(pi t)} = 2/s+e^(((25-5s)/2))((s-5)/((s-5)^2(pi^2))) You may find the following formulas useful: cos(bt + pi) = -cos(bt) sin(bt + pi) = -sin(bt) cos(bt + pi/2) = -sin(bt) sin(bt + pi/2) = cos(bt)

Determine the Laplace transform of the given function $f.$ $$f(t)=e^{(t-4)}(t-4)^{3} u_{4}(t)$$.
The Laplace Transform and Some Elementary Applications
The Second Shifting Theorem
Find the Laplace transform of the given function: f(t) = (t - 3)u_1(t) - (t - 1)u_3(t), where u_c(t) denotes the Heaviside function, which is 0 for t < c and 1 for t >= c. Enclose numerators and denominators in parentheses. For example: (a - b)/(1 + n).
