Can you guys see the attachment??

argh i have to reattach it i cant pull up the attachment scan.pdf

The problem is attached to this thread. It's the bottom problem with the chart and 4 parts to it. It is labeled 2001: AB-2; BC-2 because it was a previous AP calculus problem. If you cant tell me the answer please tell me how to do it. thank you!!!! scan.pdf

guys i need help please ive been stuck on this problem for days: An object moving along a curve in the xy-plane has position (x(t), y(t)) at time t with dx/dt = cos(t^3) and dy/dt = 3sin(t^2) for 0<= t <= 3. At time t = 2, the object is at position (4,5). Find the position of the object at time t = 3. Please help! im stuck!

And by the way, of course the standard primers will most like be beta-actin, which most scientists use for their positive controls for PCR. I dunno if you use beta actin in yours.

K i got it...i used positive and negative controls for my PCR too, along with my reverse transcription before that. I just wanted to know what they were and how they functioned so that I could get a better understanding. Thanks!

hey guys, im still a bit confused over the purpose of positive and negative controls. Can sum1 explain me the uses and give good examples so that I may understand. It would be greatly appreciated thnx!

Hey guys. Im a high school student and I need an article for my research. Can sum1 help me get it? I dont have access to colleges right now so i cant get it. Thanx for your help. The title of the article is: A reassessment of the neurotoxicity of pyrethroid insecticides. Ray DE, Fry JR. here's the abstract of the article: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=16324748&query_hl=1&itool=pubmed_docsum

I have a TI-89 titanium which is pretty advanced for a calculator (You can do programming ont hat too). By the way wat math do you take? (insane alien)

[math] \lim_{x\to\0} [/math] Now you have to rationalize the numerator and denominator by multiplying the numerator by its conjugate.

[math]1234^{1234}[/math]

Thanks man i really appreciate it.

well try to get it as fast as possible - Monday will be fine (but it would be better if I got it today). Thanks for your help man.

Hey guys. I found the abstract of this article that I really need badly. I have looked all over the Internet but could not find the full-text article and I do not have access to colleges (I am a high school student). I need it pronto because I have to enter a competition and have to finish my paper. Please please someone help me out and obtain the full text of this article and send it to my email as an attachment at translash@yahoo.com. Please guys I need your help and I know you guys are good samaritans because you help the people here on these forums. Here's the information of the article: Brain Res. 1999 Dec 11;850(1-2):249-52. Effects of deltamethrin on nitric oxide synthase and poly(ADP-ribose) polymerase in rat brain. Wu A, Liu Y. Department of Environmental Toxicology, Tongji Medical University, Wuhan, Hubei, China. agwu@ucla.edu The effects of deltamethrin on the activities of nitric oxide synthase (NOS) and poly(ADP-ribose) polymerase (PARP) and the protein expression of neuronal NOS (nNOS) and PARP in rat brain were investigated in the present study. The activity of NOS was significantly increased in cortex and hippocampus at 5 h after deltamethrin treatment, and maintained at an increased level at 24 h. The activity of PARP was also elevated at the same time points in the same brain regions of treated rats. By immunohistochemical analysis, it was demonstrated that the nNOS-immunoreactive cells were markedly increased at 24 h after treatment in the cortex and hippocampus, whereas few nNOS-immunoreactive cells were observed in the same brain regions of control and treated rats at 5 h after treatment. The immunoreactivity for PARP was also increased in the same brain regions, showing the similar time course of the induction of nNOS by deltamethrin. These results indicate that deltamethrin increases the activities of NOS and PARP and initiates the protein expression of nNOS and PARP, suggesting that NOS and PARP might play important roles in neurotoxicity of deltamethrin. PMID: 10629771 [PubMed - indexed for MEDLINE] please one of you generous guys help me! I would really appreciate it!

Yea I was thinking the same method and got the same answer. I was hoping for a more systematic and exact way of figuring it out though. But thnx anyway

What is the infinite series for this problem?

Do you have an explanation?

yes i want it in the form of notation as shown in the previous example

OK thnx. I was hoping for a more complicated answer though

[math]x = 1234 ^ 1234 [/math] express that in the terms stated in the problem above.

rrrrrrrr its suposed to be x = 1234^1234 (sumthin's up with the coding)

[math]x = 1234^1234[/math] heehee sry im kinda new to latex

Here's problem I need help on. It relies mainly on one's intuition and intelligence. Can anone hlep me out and give a full, good explanation? Every number can be represented in the standard form such as [math]\frac{100}{3} = 3.33 * 10^1[/math]. In this form the number [math]x = a * 10^N[/math], where [math]1<a<10[/math], while N is an integer exponent. Find the standard form for [math]x = 1234^1234[/math]. Include only three leading decimals in your answer, as in the previous example.

Can you elaborate please?

Hey guys i had this problem that i want an explanation for. I want a good way to solve it probably using limits or some part of calculus. Can anyone find a good way ot figure it out? Here's the problem: (TESTS YOUR INTELLIGENCE) Two cities A and B are connected by a 100 mile railroad. In each city there is a train. At one instant the trains start moving toward each other with equal speed of 50 mph. Train A had a fly sitting on it, which took off at the moment of the train's departure and started flying toward train B with a speed of 90 mph. When the fly reached train B it turned around and started flying toward train A at 90 mph. The fly bounced between the trains multiple times, each time reversing its velocity, until the trains collided. What is the total distance flown by the fly? Again, it's alright if you cant use calculus to solve this problem but I need a way to teach my classmates how to do it!!! I hope someone realy smart here can help me out! Thanks a lot for your time.
