o ok thxs the wolfan alpha thing said it was when i typed it in. It also gave somthing different

i forgot how you do a differential equation, i have the solutions. I want to know how you do the dΨ/dx i thought it would just be dΨ/dx= -A/ke-kx Its been a long summer lol

Homework Statement Well this is a physics problem, need find the potential function Homework Equations \Psi =Axe-kx A and k are constants I need to find d2 \Psi/dx2 The Attempt at a Solution I thought u would just take the derivative two times but just d\Psi/dx = Ae-kx-kAxe-kx...

nvm what i was thinking would not work

i know its expanding lol just think of this as different universe that's static. We have a project and one part of it is to create like a homework problem. it has to be on dark energy, so i figured my problem would be using that formula and showing the universe is static, like what Einstein thought

Homework Statement how can i show the universe is static and not expanding, how it really is. Homework Equations \OmegaM=... \Omega\Lambda=... The Attempt at a Solution "The expansion history of the universe depends on the amount of matter (gravity), quantified by \OmegaM...

Hey I have a project about dark energy. Part of it is that I need to make some kind of homework problem with this topic. The article talked about using 1a supernova data to see the expansion of the universe. I was I would first calculate the luminosity or whatever they did. Than using that...
