Homework Statement I need to find the volume of a cone covered with a plane z=h using multiple integrals. The scheme is something like this: Homework Equations Formula of the cone x^2-y^2-z^2=0 The Attempt at a Solution I tried to integrate ∫∫∫(x^2-y^2-z^2)dxdydz in all...

The first part of your reply was just what I was expecting, so thank you for that. I have given all the information concerning the problem, so I don't know if I can express it in terms of eigenfunctions, in case I haven't missed anything. Can you help me formulate an answer, what are the values...

Homework Statement In an infinite potential hole, the ground state is described by the wavefunction ψ=A*sin(\frac{πx}{a}). Does the ground state have a definite momentum? If not, then what are the values of momentum in ground state? Homework Equations Wavefunction ψ=A*sin(\frac{πx}{a})...

Homework Statement I have to show that the impendance of a parallel RL circuit would be the same in measure as the impendance of a non-parallel RL circuit (sry, don't know how to express this in English). I have to show this so that the inductivity stays the same in both cases but the...

bump.. anyone?

Homework Statement The scheme is here: http://img196.imageshack.us/img196/9366/lcre.jpg G generates soundwaves, Re are all 10 ohm resistors , R is an 98000 active resistor, L=100mH, C=0.253 μF The assignment was to measure the voltage through different parts of the circuit near resonance...
