Homework Statement Suppose that a and b are real numbers. Prove that if a < b < 0, then a^{2} > b^{2} Homework Equations Properties of inequalities? The Attempt at a Solution This is how I did the final proof: Given that a and b are real numbers and a < b < 0, we notice that...

I have a simple question that probably has a complicated answer. How do I prove theorems? Like, prove that the square root of 2 is irrational (or other things). I mean, I can do some geometric ones, but the symbolic ones confuse me. It makes sense when I read one, but I can't do one myself! I'll...

God I'm stupid, you're right about the velocity and the force thing. Okay, and I need to use Newton's second law. Also, I've never taken calculus-based physics so I don't know much about how to put calculus into physics. I don't know exactly what it is I am trying to do other than learn this...

Hello, this is my first post. I'm not a big fan of long introductions, so I'm going to spare you my life story, for now, and discuss something I thought about on my lunch break today. Alright, suppose there is a rigid sphere of radius \textit{r} traveling at a constant velocity, \vec{v} in a...
