I'm supposed to introduce myself

[Konhbri]

I've been a lurker here for a bit, I already posted a homework question which I guess I am not supposed to do. I am an undergraduate in Physics and Mathematics at a UC with a minor in poli-sci. I look forward to answering (and more commonly, asking) questions on here.

Welcome to PF. I see that you already got some good answers to your homework question, so I say you are doing OK.

Not at all. Your first homework post is well done (and you are getting help with it already).
