..[itex]\infty[/itex]

[itex]\sum[/itex][itex]\chi^{1-\chi}=arcsinh(\sqrt{6})[/itex]

..[itex]\chi=1[/itex]

(PS does anyone know how to type summations much faster than using the sigma notation, then typing below and above etc. I am not too familiar with Latex

Another summation that i would like to confirm:

..[itex]\infty[/itex]

[itex]\sum[/itex][itex]\frac{1}{\Gamma\chi}=e[/itex]

..[itex]\chi=1[/itex]

This can be derived by representing e^x with a summation.
