On the Religion and Spirituality section, we are constantly getting spammed by creationists with their nonsensical objections to evolutionary theory. We usually tell them to ask their questions in the Biology section and leave us alone. Biology regulars: do they ever show up?

I was wondering if anyone would tell me how to calculate an event in a combination problem. For example, how would you calculate 4 choose 2?
Is it a simple calculator function, or is it something more complex?
If anyone can help, that would be awesome!!!
Thanks

I'll be using Maple to figure this out, but I can't quite figure out the process. I need to find the minimum and maximum areas of a triangle if two of its vertices are (2,-1,0) and (3,2,2) and its third vertex is on the curve r->=<1+cost,sint,0>, t between 0 and Pi. To find the area of the triangle, I know I use 1/2 the cross product of the 2 vectors formed by the known vertices, but how to minimize the area I get stuck. Can anyone give me a clue?

I need a map of the tombs in The Valley of Kings and The valleys of Queens as well. It would be nice to have different picture of the tombs as well, at least the major ones. A web address that brings me straight to it would be GREAT!!! Thanks

Astronomy can be a bit confusing. Especially when the three terms have basically the same units.

The cooling system of a certain foreign-made car has a capacity of 15 liters. If the system is filled with a mixture that is 40% antifreeze, how much of this mixture should be drained and replaced by pure antifreeze so that the system is filled with a solution that is 60% antifreeze?

a number like 123 or 479 is called a rising number. That's because each digit in the number is greater than the digit to its immediate left. how many 3-digit rising numbers are there? show all ur work. it is hard but try . thank u.

Alright, so here's how the game is played:

You're trying to make as many numbers as possible using 4 4's or less, in an attempt to try to prove an old theory: "You can make any whole number using only four instances of the number four and commonly used mathematical symbols."

So so far, the symbols allowed are:
1. All standard mathematical operators (+ - * /)
2. Factorials (4! = 4*3*2*1)
3. Square roots, arbitrary roots (the index is included in the 4 4's)
4. Repeat signs (denoted with an apostrophe ' or grave accent `, ex. 0.4` = 0.4444444.....)
5. Exponentiation (denoted with a caret ^, 4^4 = 4*4*4*4)
6. Decimals do not require a leading zero. So you could put .4 instead of 0.4.

I'll start:
0 = 4-4
1 = 4/4
2 = sqrt(4)
3 = 4 - 4/4
4 = 4
5 = 4 + 4/4
6 = 4 + sqrt(4)
7 = 4 + 4 - 4/4
8 = 4 + 4
9 = 4 + 4 + 4/4
10 = 4 + 4 + sqrt(4)

And the next person would continue from 11, 12, and so on, and introduce new symbols and explaining them if necessary.
