I am currently trying to show that two numbers are significantly different but I am unsure of how to do the statistics. I'll provide a brief description below. I have 4 arrays: Array A Array B Array C and Array D I can determine the difference between 2 arrays using a student's t-test From...

I think what happened was that we were talking about two different experiments, it's ok though. And what you said makes a lot of sense. You're right, it's not entirely satisfactory but it does answer my question better than any other source has. Thank you.

It can't, that's a mistake on my part...it's the down-converter that can potentially indicate the path taken by the photon. Sorry. That's besides my main concern though, I don't see how a double split experiment doesn't constitute observation of the photon?

So I'm embarking through Brian Greene's magnificent book The Fabric of The Cosmos and in the quantum section he goes through the whole idea about how observation of a particle leads to collapse of the wavefunction into a definite location. He also uses the double slit experiment for photons and...

hmm...well you know that deltaH = qt and qt/t = delta S...give that a try?

so with points ii and iii...what if b_n was divergent and the lim was 0? What would that mean? And with iii, what if the lim goes to infinity and b_n converges? what happens then? Thanks.

W = FD F = VDg W = \int (1000)(9.8)(V)(D) This is where I run into a problem...I put that VD equals (pi/16)y^3dy. I really am not sure what to do from here because that's where my mistake is. Please help.

You have a container which has the volume of y=x^4 from y=0 to y=16. This tank is filled with water...how much work is required to pump all of the water out of this 16 meter tall tank. I'm not too sure where I went wrong here because I know work is the integral of Force times Distance. Please...

http://www.math.sunysb.edu/~leontak/prfinal.pdf http://www.math.sunysb.edu/~leontak/solpf.pdf Hi I was unsure of the explanation of the answer for question 13 part a. I understand everything up to where he finds the pattern shown by the recursive relation but after that, I'm not sure how...

Hi, I'm preparing for my calculus II final and I had a question about Power Series. I'm posting the link for the answer solution to a practice exam (it's in pdf form) and I will ask questions based on that. http://www.math.sunysb.edu/~daryl/prcsol3.pdf On problem 12 it asks for the fifth...

cyclovenom...you were a great help...I am now done with my math homework and confident on the unsure questions...I am sure that you'll be helping me out again in the near future as I am quickly approaching finals time. Thanks again, take care.

AH! {x^2}\sum_{n=2}^{\infty} {n}{(n-1)}{(x^{n-2}) is just x^2(f''(1/1-x)) hah, thank you so much!

ohhh ok, Let me try...thank you so much!

wait I don't see why it's x^(n-2)...when you change the series from n=2 to n = 1...x^n becomes x^(n+1)...so then when you extract x^2...it becomes x^(n-1) also, if I continue the problem with my numbers...I get to a spot like this: x^2 \sum_{n=1}^{\infty} ({n^2x^{n-1}) + ({nx^{n-1})...

Can someone also verify this infinite series for me?: Evaluate the indefinite integral as an infinite series: \int {e^{x^3}} = \int \sum \frac {x^{3n}}{n!} = C + \sum_{n=0}^{\infty} \frac {x^{3n+1}}{(n! (3n+1))} I posted my answer in there, does that look about right? Thanks.
