Yes! Thank you very much! Very creative and intelligent answer!

We have a system of two unequal oppositely charged point charges, of which ##q_2## is smaller and ##d## is the distance between charges. There is an equipotential spherical surface of potential ##V=0## that encloses a charge of lesser absolute value. The task is to find parameters of that...

Thanks. Maybe I should look into The Chicago Manual of Style?

If not official, then unofficial, but widely accepted? If yes, are there some separate style guides for physics and computer science texts?

z_k=\sqrt[n]{u}=\sqrt[n]{r}e^{i\left(\frac{\phi+2k\pi}{n}\right)}, k=0,1,2,...,n-1 and z_k=\sqrt[n]{u}=\sqrt[n]{re}^\frac{\phi+2k\pi}{n}, k=0,1,2,...,n-1 Which one is incorrect (note that in the first, e is out of the root)?

Have I wrote something non-understandable since English is not my first language?

Question 3: We have a damped harmonic mechanical oscillator - a moving body on the spring.If force of damping is proportional to the speed of that body then: a)none of the statements below is true - CORRECT b)frequency decreases with time - INCORRECT,SINCE FREQUENCY IS NOT FUNCTION OF...

I`ll do that then.Thanks. It was a misunderstanding.I asked for entire topic to be deleted so that I could open a new one.

But I only believe in C/C++ Bible.

Dr Transport,thank you for your reply.

...exclusively with exercises from MATLAB? I found many theoretical books,but that is not what I need.

Question 2: The second question is about equation which describes a wave in air which originates from vibrating string attached to both of its ends and strained by some force.I know that people in United States and UK represent this equation in different form,so I`ll describe every...

Question 1. From kinematics we have a=\frac{\mathrm{d}^2s}{\mathrm{d}t^2} which means,as I understood it:to get the acceleration,we first derive distance with respect to time,then again derive the result of that operation with respect to time. If so,wouldn`t be more appropriate to write...

When some problem is solved and the "first" result is given at the end followed by this symbol and "second" result.

DaleSpam & Mk, thank you for your time and answers!
