someone could to show how to demostrate the semiconvergent following sequences
\sum _{m=1}^{\infty } (-e)^m=\frac{1-e}{2 (-2+\text{Sinh}[1])}
and
\sum _{m=1}^{\infty } (-1)^m \text{Log}\left[\frac{1}{2}+m\right]=\text{Log}\left[\frac{\sqrt{2} \text{Gamma}\left[\frac{5}{4}\right]}{\text{Gamma}\left[\frac{3}{4}\right]}\right]
thanks
