Thank you, DrClaude. Now I got it.

Moved from technical forum, so no template is shown Summary: I have the expression sin(2x) + sin(2[x + π/3]) and I have to write this in terms of a single function (a single harmonic, rather saying). But I don't know how to do this, and... it seems a little bit weird for me, because I'm merging...

Yes, I got it. Thank you for the explanation, I was very confused but now I can see a little bit better. I will explore more to see how far I get.

So, I don't have a specific initial state. Instead, I have the general expression χ(0) = (a b). I was thinking in use the consideration of the book (a = cos(α/2) and b = sin(α/2)). But... in the end, precession seems like it's going to get weird (am I right to say that the precession it's going...

I just tried to find the eigenvalues (for the energy), obtaining E = ±(γħ.√(Bo² + Γo²))/2 and the corresponding eigenvectors for the H matrix. But I don't know what to do to create de state vector χ.

Hello everybody, I have a question about thermal radiation: Imagine a body at a certain temperature T, in an environment with nothing around it. Theoretically, this body emits radiation according to its temperature (the maximum radiation is described by the Wien relation); If it emits, it must...

I was reading a paper about deterministic chaos, where the author had commented that non-linear systems can be affected by this. My question is whether some linear systems can also have chaotic behavior. It is possible? Thank you

Thank you all, was very helpful to me and nice to understand.

Thank you, I checked the example, it's very interesting.

I have my first question. It's about entropy in the Carnot cycle and I'll try to be direct. The equal sign in the Carnot cycle efficiency equation is related to the fact that the total entropy doesn't change at the end of the whole cycle (being related to the fact that the heat exchanges occur...

Hello, My name is Ben-hur, I'm a brazilian physics student - my college course is oriented to train teachers in the area, but I would like to work on studies and researches (probably about climatology or space sciences); I'm young in the scientific study, since it is my first graduation...
