anuttarasammyak replied to the thread I Why work is PdV and not (P+dP)dV in an isothermal process?.dP dV is infinitesimal of second order. We can disregard it in calculation. -
anuttarasammyak replied to the thread I Useless continued fraction for 1.Generalizing 2 to integer n, the equation is $$x^2-nx+1=0$$ $$x=\frac{n \pm \sqrt{n^2-4}}{2}$$ So we know for x to exist ##|n|\geq 2##...

anuttarasammyak replied to the thread I Useless continued fraction for 1.Say RHS continued fraction is x, we have an equation $$x=2-\frac{1}{x}$$ $$(x-1)^2=0$$ $$x=1$$ So we know if x converges, x=1. If it...

Like.
I ran across the very interesting https://arxiv.org/abs/quant-ph/0302081, "Geometry of the 3-Qubit State, Entanglement and Division... -
anuttarasammyak replied to the thread How to move from the space of moments to the space of energies?.You may do this substitution anywhere. Just please be careful for taking derivatives as I posted #2.

anuttarasammyak reacted to happyparticle's post in the thread Initial conditions for orbits around a wormhole with Like.
You do understand the question correctly. I'm not sure if I need to use the angular momentum. Basically, I have to find a relationship...
