I worked out that the first derivative was 1 over 1 - cosx, but my calculator says something different, 1 over cosx - 1. Help?

A number is "cute" if it has exactly four positive integer divisors. What percent of the first 25 positive integers are "cute"?

OK, my father says that his father's mother's mother was Shoshone. My mother says this is not possible, because apparently my brother and I were the only grandchildren on my father's side with brown eyes, which our mother has. My father's eyes are green, same as his two brothers' (who both married blue-eyed women), his father's eyes were blue, and his mother's eyes were green. I do not know the eye color of my father's paternal grandmother, or of any of my father's cousins on the paternal side. My mother's 7 siblings have various eye colors.

From this information, is there any way to tell whether my father's father's mother's mother was Shoshone? If not, what information would I need to determine, by eye color, whether this is possible? I would be proud to have some Native American heritage, but the story's source, my grandad, had a propensity for tall tales, so I don't know what to think...all the family records were lost in a house fire...should I just hire a geneologist?

Every point in the plane is colored either red, green, or blue. Prove that there exists a rectangle in the plane such that all four of its vertices are the same color.

I can't my head round this and wondered if anyone can help me! When filling electron orbitals and using the building up order (1s2, 2s2...etc) I don't understand the way the d orbitals fill. I get everything else about it but; e.g. chromium. The configuration is [Ar]3d4, 4s2 but why is it not just [Ar] 3d6? Why does the 4s get electrons when the 3d is not yet completely filled? Can someone please explain this :)

Another question here. An example would be:

5 m and 6 m.

If you are given those two sides of a triangle, what can you conclude about the third?

Once again, theres probably a really simple answer but I have no idea.

since the coreolis effect causes draining water to spin one way in the northern hemisphere and the other way in the southern hemisphere, what does it do at the equator? Is anyone taking a bath at the equator right now?

square (h) +[hsin(theta)* dh/d(theta)] =1
this can be read as : h square + h into sin theta * differential of h w.r.t. theta = 1
here h is function of theta
h= h(theta)

Just a little quiz to see who's clever

Electrical demands: 7,500,000 kilowatt hours yearly with 580,000 exclusively for the illuminations. Eighteen transformers handle the flow of current and in case of breakdown, 3 electrical groups will automatically take over. More than 100 bulb models are represented in the 10,000 that light up the illuminations. The electricians must regularly change them, a task that involves climbing the structure itself. The entire installation relies on a network of 80 kilometers of electrical cables. Furthermore, 65,000 square meters of drinking water and 705,000 kilowatt hours of cooling and heating are also necessary annually.
