So I am trying to write out Gauss' law for gravitation and I am having a hard time figuring out how to write it out without an error.
I am currently trying to write in an equation block
but obviously TeX is picking up on the fact that I have
\piG and not
\pi. I can delineate between the two by adding a
\ to space them out but that looks funky in the equation. Any help is appreciated.
