Suppose I am playing a game where I roll some dice, and must use only combinations of elementary operations (addition, subtraction, multiplication, or division) to make an equation using each number rolled exactly once. For example, if I roll four six-sided dice, and get this: 2, 3, 3, 4 A...

Hello, I have been very obsessed with a board game called Hex lately. I am trying to calculate the number of completed states (all positions filled in) on a 3x3 board where a certain player wins, given that some positions are already filled. I have attached a diagram illustrating what I am...

I figured it out a while ago. If y=-x, the limit as x->0 is infinity, not zero.

Homework Statement Find the limit as (x,y) approaches (0,0): Homework Equations x^2/(x+y) The Attempt at a Solution I have tried replacing y with 0, mx, x^2, etc. (and likewise with x), and all give me a limit of zero. So I tried to think of ways I could use the definition of a limit...

Are they derived from accepted laws and then tested, or are experiments carried out first and then a function is searched for that matches the results (or possibly both, or neither)? For example, how would an equation that gives the probability of electron locations be thought of? My "gut...
