This is my first post here and I hope that I am in the correct subforum .
So, I have this equation:
Also there is a # before the curly bracket, I don't know why the equation writer won't allow me to put it.
Now to the question. Disregard what the variables are, I just want to know how this equation works. How can I interpret it? If I have the variables how do I get rGm?
Thank you for your help.
