### Re: Average Distance ot the Edge of a Square

Yeah, I would go with your initial thought. Find the average diameter by angle:

If you use the perimeter in place of circumference, 4 divided by the above gives the answer.

### Re: Romantic films that are not terrible awful travesties

Milk & Money is one of my favourite films. It's not soppy and it's not particularly cheesy. It's unrealistic but that's ok because it's absurd and hilarious.

### Re: (homework) exponential equation problem

When you take the log of both sides, what you do get is a picture of their relative exponential growth rates. You could observe the growth factors. The growth factor of 2 x + 5 x is limited to between 2 and 5. So 7 x always grows faster (or when x is decreasing, 7 x always decays faster). Therefore,...

### Re: "Why" is the Euler-Mascheroni constant near sqrt(1/3)?

In fact, someone left a comment linking to this, which looked promising at first glance, but I had trouble filling in the details. I'll guess coincidence for this part for a start. The 2nd-degree Legendre polynomial has roots ±sqrt(1/3) because it's an integral of 3x such that f(1) = 1, and the mat...
