Graduate How is the Relativistic Larmor Formula Derived Using Dot Products?
This (http://www.ita.uni-heidelberg.de/research/bartelmann/Lectures/elektrodynamik/edynamik.pdf ) lecture has a derivation of the relativistic Larmor formula I once comprehended - around page 159. There are two catches: 1) It's in German (but many formulae, so you might get it) 2)I don't...- Yuu Suzumi

Square of transpose of two matrices
Thanks! That is a policy I can endorse. We want the OP to feel proud of his solution, after all.- Yuu Suzumi

Square of transpose of two matrices
Yes. At least that's what I got too :-) Do you know where the thread is in which they describe how much we are allowed to help I am HW forums? I can't find it and therefore I am limiting myself to remarks like above.- Yuu Suzumi

Q: How to compute P(X=200 and Y<150)?
Be careful! When the six is removed, how many numbers share the 800 trials?- Yuu Suzumi

Q: How to compute P(X=200 and Y<150)?
If you know the number 6 appears 200 times, what would you say about the way in which the outcomes of the remaining 800 rolls are distributed?- Yuu Suzumi

With the hint given by haruspex you can arrive at one of those! Find two ways to write ABA!- Yuu Suzumi

Old questions: Should you answer them? How old is too old?
I second that! I shall try to answer the questions for which I feel that I have a good answer, regardless of posting time. Provided they are generally useful (meaning that someone could have a similar problem in future)- Yuu Suzumi

Thermodynamic Proof: Show PV^k=constant
It has been a while since I last did thermodynamics. But why may I not write this: k \equiv -\frac{\frac{dp}{p}}{\frac{dV}{V}} = \frac{Vdp}{pdV} and then, using that I have an isentropic process: k = \frac{dH}{dU} = \frac{C_p}{C_v}. If this is still valid, then k can not be constant in a...- Yuu Suzumi

Thermodynamic Proof: Show PV^k=constant
Are you sure they are claiming this more generally than for an ideal gas? I remember that even for Van der Vaals Gases this expression has to be modified in a way similar to the equation of state!- Yuu Suzumi

MATLAB Plotting a potential function in MATLAB
Hello Maxtor, I believe the surf() function in MATLAB to be suited for your purposes. After defining \phi_1, \phi_2, V in MATLAB you would use it in this way: surf(phi_1, phi_2, V). Information and examples are available here: http://www.mathworks.de/de/help/matlab/ref/surf.html All the...- Yuu Suzumi

Undergrad Convexity of a function I don't understand
Is the argument of f perhaps a vector and the x_i the components thereof? I am sure they are not meant to be the same.- Yuu Suzumi

Do you remember what (AB)^T is in terms of A^T and B^T? Have you tried using that?- Yuu Suzumi

Why Are Pointers Necessary in Programming?
A very paedagocical example is given here: http://stackoverflow.com/questions/5680164/why-pointers-are-necessary-in-programing I am not copy-pasting it in order not to take credit for other peoples explanatory skill.- Yuu Suzumi
