I honestly don't know if I did or not, and its probably nothing. Last year, I fell pretty hard on my elbow a few times (sports) around the same spot. When it happened, my forearm started to swell up, right above my elbow, and it hurt to even touch it. I iced it, and didn't really do much for the next few weeks, but then when I started skating again, since its my leading arm, every time I fell, it would be right on that spot. Its pretty much constantly swollen, but it doesn't really hurt that much, and I have full mobility and all that, but, when I fall, it just swells up like crazy and hurts like a b****. Its a little discolored. I can feel stuff moving around in there, if rub my finger on it, lol. My main concern is, if it was messed up and fractured or something, it probably would have healed up wrong. If it did, would they need to re-break and set it? (The only reason thats a concern is because snowboarding season just started, and I payed about $500 for bus trips and lift tickets in advance, and if it is going to need to be reset, my parents would want it to be ASAP. And no, they didn't pay for all that either)

Theres this really stupid application my friend is filling out, and its asking what problems are there in our age group that one can solve (age group being 13 - 17) what are some examples of problems?

r=p/cos(theta-phi)

a) x-y-6

b) y = -2x+4

I know how to find everything by phi. and you don't need theta because this is the equation for a line.

Dogs have 70 chromosomes. How many chromosomes would they have in the following cells: haploid, diploid, somatic, homologous pair, tetrad, gametes

(I don't really care about the dog part, all i need to know is how many, in relation to n, the number of chromosomes the organism has. I know that gametes have 1/2 the number of chromosomes of the dog, so it would be 1/2n)

I have a project I need to do, but I have not been able to find the statistics of which species of bird has had more bird flu cases. (yeah, I know there won't be any 'exact' answers, but I just need some kind of approximation, so that I can make a graph for the presentation)

Say that I have something in sigma notation, any series, how would I find r?

I'm 14 years old and I have been recently having some pretty severe memory loss problems. I can't remember what I was thinking about just seconds ago (That part isn't major, so I might be overreacting) I will be typing a paper for class and I just forget the topic completely. Today, I was with a friend, who I have known since September, and I just completely forgot his name. I could not remember anything other than that it started with an "A". This is seriously messing me up. (Just so you know, I'm not a drug user of any kind, I'm not taking any sort of medication, I am not depressed, and I am sort of stressed out with school (I heard that stress can be a cause of memory loss, but I'm not any more stressed out than usual))

I need to know how to express cos(arctan 2x) as a function of x. I know that the end result is 1/sqrt(1+4x^2) but i don't know how to get there.

In relation to photography, is a thin negative darker, or lighter than a negative is supposed to be?

I would like to know how much it would cost to be removed (if needed) and if it is painful or not.
