F.o.i.l or Box? What is the better method the F.O.I.L method or the (I am not sure of the offical name) box method(where you make a box with 4 squares) to factor. Are there any other methods availible?

If Darvin knew about genetics or even about what mendel was researching, how do you think it would have changed his theories?

Hi, we have a particle in a potential. We are asked to state what information we need to have a well defined problem, and since the equations of motion are second order wrt time derivates we need to know the position of the particle initially and its velocity. We are then asked "in the quantum...

I'm looking for some math software that I'll be able to use through university. I'll be doing honors in physics next year. I know there are nice TI graphing calculators but how do they compare to computer software? What are your opinions on Mathematica vs Maple vs ______?

1) In the basic probability theory the concepts of mutually exclusive events and independent events share prominent roles, can two events be both mutually exclusive and independent at the same time? 2) What are two vital concepts and the relationship between "Critical Value Method" and the...

Anybody notice it? I think it looks much better than the old one :smile: http://img415.imageshack.us/img415/1435/pfnewicon3eq.th.png Here is the old one, for those who don't remember: http://img415.imageshack.us/img415/5804/pfoldicon0vx.th.png

hey guys, this is my first post. however! i have been lurking over this forum for quite sometime and i have have learned a lot of things from this forum, and it has been very helpful! i came across this question that is giving me a heartburn and i have scanned it below: how do you go...

I am trying to compare two probability distributions. I tried the chi-square test, but that requires binned data, and all I have is probability. It seems to work if I ignore the rules about degrees of freedom and just use df=1, but I doubt this is statistically valid. I tried to 'unnormalize' my...

Comparison between y=sinx and... y+3=2\sin(3x+\frac{\pi}{2}) vertical stretch by a factor of 2 horizontal compression by 1/3 no reflection in the x or y axis 30 degrees horizontal phase shift to the left and 3 units down vertical displacement. Can someone please check this?

Hi, I've been thinking about the comparison test for integrals. Usually when I have an integrand where the denominator is f(x) + something positive I can usually find a suitable bound without much trouble. However when the denomoninator of the integrand is f(x) - something positive finding a...

Explain how it is possible for 30,000 kg of snow at 0 deg C to contain more heat energy than 1 mL of liquid water a 100 deg C. ( Assume a pressure of one atomsphere).

Alright, this question may seem simple in comparison to some of the questions in here, but whatever. So, I've been doing some reading on Quantum Superposition, and I was curious as to whether or not anyone has ever applied its principles to Spherical Standing Wave Structure of Matter. -Liam

SpaceTiger has created a very valuable thread on Mainstream Cosmology. For good scientific practice it is important to compare standard theories with testable alternatives, however ST's thread is not the place to do it. The theory of Self Creation Cosmology (SCC) presents itself as such a...

I am giving a presentation on helium 3 for a future energy source and i am looking for a way to describe (and compare) how much energy is released in a helium 3 reaction (D-T would be fine). some thing that would be clear to people who have no science background. (i.e. the amount of H-3 that...

I'm supposed to compare the series \sum_{n=0}^{\infty}\frac{1}{n!} to some other series to see if the one above converges or diverges. I have no idea of what to compare it to. I know by the ratio test that the above series converges, that is if I'm doing the ratio test correctly...

Each of the following statements is an attempt to show that a given series is convergent or divergent using the Comparison Test (NOT the Limit Comparison Test.) For each statement, enter C (for "correct") if the argument is valid, or enter I (for "incorrect") if any part of the argument is...

Test each of the following series for convergence by either the Comparison Test or the Limit Comparison Test. \sum_{n=1}^\infty \frac{2n^4}{n^5+7} this diverges using the p-series and comparison test right? p <1 \sum_{n=1}^\infty \frac{2n^4}{n^9+7} and this converges right? because p >...

Have you looked at any of these monitors? http://accessories.us.dell.com/sna/ProductDetail.aspx?sku=320-4221&c=us&cat=snp&category_id=6198&cs=04&l=en&mnf=694&Page=productlisting.aspx http://www.apple.com/displays/specs.html...

Show that they are the same number of points in a line, in a plane and in the space. I have one more question: Which set has a cardinal number greater than the continuum. Why? Thanks in advance.

What is the greatest decade for music. This is overall music in terms of depth, quality, sound, talent, etc..

I can't understand this \sum{A_n}\leq \sum{B_n} having said this if \sum{B_n} converges so does \sum{A_n}, okay that makes perfect sense but then the second rule of comparison is if \sum {A_n} diverges then so does \sum{B_n} diverges too...can anyone tell me how that makes sense...

Very objective, clearly written: http://tinyurl.com/6d9rr I won't be hosting this for tooooo long, so please get it (only 1.5mb) and mirror it if you can assist me. I'll be taking this down tonight or tomorrow :)

hello everybody! i have to find match between two different peptide sequences (looking for related sequences), but don't know where and how i can do it. i have very little bioinformatic background. i hope for some help. thanks alot!

I have to use the comparison theorem to find if the function converges or diverges. Any ideas as to what I can use to compare the function to?? integrate: sqrt(1 + sqrt(x))/sqrt(x)dx Using the comparison theorem!

What is the ethical difference between the following situations? Also, what would be the ethical possible courses of action (or non-action) in each situation. A) Someone is going to shoot and kill some "innocent" person. You can stop him, but you have to kill him to do it. B) A boulder...
