Trying to find the Laplace transform of

$\frac{\mathrm{cos}t}{t}$

It comes out as infinity, but that doesn't make any sense.

Does this mean that this function doesn't have a Laplace transform or is something wrong here?

Use Laplace transforms to solve the initial value problems.

$y{y}^{\prime}=\delta \left(t\right)-\delta (t-3),y\left(0\right)=1,{y}^{\prime}\left(0\right)=0$

Use Theorem 7.4.2 to evaluate the given Laplace transform. Do not evaluate the convolution integral before transforming. (Write your answer as a function of s.)

$L\{{t}^{2}\cdot t{e}^{t}\}$
