Pade Approximants: Factors to Consider?

I have never used Pade Approximants before but am about to take the first step. I have a few questions and am looking for advice. The data to be approximated is a non-linear angular quantity, θ, which is a function of parameter k and has been computed numerically. I am hoping to find a relatively si...

Store Wine in Fridge?

I recently bought a few bottles of wine I probably won't drink right away. Considering that it is summer, and the temperatures here are pretty warm, it made me wonder if I should store the wine in the fridge. We don't have a wine cellar. Any advice? Should wine be stored in the fridge until it is re...

Loop Unrolling: Suggested Interval?

I am about to write a small program in C++ to illustrate loop-unrolling as a method of speeding up program execution for small loops. I am looking at an old program written in FORTRAN 77 that used an interval of 5. For example: for (i = 0; i < LIMIT; i+= 5){ a[i] *= scalar_number; a[i + 1] *= scalar...

Re: Mapping an sine amplitude to angle

"brain_ofj", did you ever figure it out? It looks like the inverse of an equation in polar notation. I.e. - Instead of s = r * (θ) it is θ = some function of r. For example, θ = 90 (1 + sin 2 (θ)), or some other function instead of sin 2 (θ)--something that will get you close to 180, like ...

I have a pretty simple question: How do include a square root sign in a post without using TeX? A single square root sign is all I want in a post, so I don't need the power of the math and imath tags. There are several guides and references for BBCode, but none of them seem to include special math s...

My grandmother's vegetable soup is my favorite; nobody can make it like her.

My other favorites include French Onion, vegetarian Borscht, my own homemade Clam Chowder, and Lentil and Bacon.
