Thank you. Once I added the second term it was very clear how I should proceed.

Homework Statement [/B] I'm trying to solve the following problem. (a) was easy but I am stuck at (b). Homework Equations [/B] Since we are told that the Hamiltonian is conserved, and the answer is in terms of the uncertainty of H, I assume I have to use the conservation of uncertainty...

Someone was faster :P

Which limits of integration are you using? Aren't h(y) and p(y) greater than zero if |x| < 1? The integral should be positive.

When phsicists talk about physics, they have given words to mathematical quantities. Ultimately, they are talking about measurable quantities that are well defined, and they are talking about equations. The 2nd law of thermodynamics is just an equation, and entropy is a well-defined physical...

##(-1)^{2n}=1##, so in your example the answer alternates between ##1/2## and ##-1/2##. The answer is right, however, for this example, but I meant the question in a general manner. What I meant, is that if you have sequences ##(x_n), (y_n), (\overline{x_n}), (\overline{y_n})##, then you can...

I copy my edit in case you didn't see it: The intuitive idea behind limits of multivariable functions is that you should be able to approach the solution in any curve you want, and the limit should exist and stay the same. In this case, as you comment, the curve ##y = mx## gives different...

This is my first non-introduction post in the forums, and I'll be testing how everything works. I hope to be able to answer your question correctly, however. First of all, your function ##f(x) = \frac{xy}{x^2+y^2}## doesn't converge because it doesn't follow condition (iii). Take, for example...

Hello, I am a second-year student majoring in mathematics and physical engineering. I plan on mostly lurking, but I might be active on occasion.
