Hi Chet,
Thanks for your answer.
The pressure change is indeed minimal, and I had difficulties understanding how this is relevant at high-school level.
But I'm glad I understand how it should be taken into account.

Hi
I am tutoring a pupil in high-school out of necessity (no other teachers avail), while I am not so acquainted anymore with chemistry. The pupil showed me a question concerning the calculation of the reaction enthalpy which looked somewhat as follows:
1. Problem statement, all variables...
The problem is solved in the meanwhile. The result is
\vec{u}\cdot\left[\left(\check{\vec{L}}\check{\vec{u}_r}\right)^T\cdot\vec{L}-\left(\check{\vec{L}} \cdot \check{\vec{u}_r}\right)\vec{L}+\vec{u}_r \left(\check{\vec{L}}\cdot \check{\vec{L}}\right)-\left(\vec{u}_r \cdot...
Hi,
I need to let an operator act on a scalar function. The operator is however in a very cryptic form, so I would want to work it out a little bit. I get stuck in the process. The operator is:
\vec{u}\cdot\left[\vec{L}\times\left(\vec{u}_r\times\vec{L}\right)\right]f
Where \vec{L} is...
Hi
Thanks for the hints, it has helped me a lot. I hadn't heard about the incomplete Bessel functions until today. However, I think the identity for the regular Bessel functions is easier to use in this case, as it results in an integral of a single exponential function (I was indeed using...
Hello all,
I am searching for an analytic solution to an integral of the following form:
I[q',k\rho\,]=\frac{1}{\pi}\int_{0}^{2\pi}e^{jq'(\phi-\phi_0)}e^{-jk\rho\sin(\phi-\phi_0)}d\phi
In this equation, q' is real and k\rho is real and positive.
Also, the following integral is closely...
Hi
I just got an introduction in complex analysis and some things are still not so clear. What troubles me the most is a property of taking the power of a complex variable. We have seen that:
(z^a)^b = z^{ab} e^{2ki\pi b}
I can prove that formula but I can't understand it. Does this mean...
