comment FFT: Does the result of Nlog_2(N) stand for total operations or adds and multiplies?
This integer sequence in the oeis might be relevant: oeis.org/A059975 "n*a(n) is the number of complex multiplications needed for the fast Fourier transform of n numbers"

Ok, Thank you for the comment. I was not aware of math being independent of time.

comment A series: $1-\frac{1}{2}-\frac{1}{3}-\frac{1}{4}+\frac{1}{5}-\frac{1}{6}+\frac{1}{7}+\cdots$
The terms in your sum $b_n$ are positive for: 1,5,7,9,11,13,15,17,19,22,23,26,28,29,32... and negative for: 2,3,4,6,8,10,12,14,16,18,20,21,24,25,27,30,31... Neither sequences are found in the oeis.

comment Calculate residue of $\text{res}\dfrac{\sin z}{e^{z} -1}$
It is possible to evaluate this in Wolfram Alpha in two steps using: Reduce[Exp[z] - 1 == 0, z] and: Table[Residue[Sin[z]/(Exp[z] - 1), {z, 2 I [Pi] n}], {n, -6, 6}]

comment Find the inverse laplace transform: $\frac{1}{{{{({s^2} + 1)}^3}}}$
Mathematica says: $\mathcal{L}_s^{-1}\left[\frac{1}{\left(s^2+1\right)^3}\right](t)=\frac{1}{8} \left(t^2 (-\sin (t))+3 \sin (t)-3 t \cos (t)\right)$

comment How to find prime numbers
You might want to try this Mathematica command in Wolfram Alpha: Table[(Exp[MangoldtLambda[n]]^(-MoebiusMu[n]) - 1)/(n - 1)*n, {n, 2, 32}] which outputs: {2, 3, 0, 5, 0, 7, 0, 0, 0, 11, 0, 13, 0, 0, 0, 17, 0, 19, 0, 0, 0, 23, 0, 0, 0, 0, 0, 29, 0, 31, 0}
