Apologies I didnt realize it was necessary

I am having a little trouble with a problem I am trying to solve. Given three particular solutions Y1(x)= 1, Y2(x)= x and Y3(x)= x^2 Write down a general solution to the second order non homogeneous differential equation. What I have done so far is to realize if Y1,2 and 3 are solutions...

Or perhaps to use one solution and contain all constants using Abel's theorem?

Just a question about the theory of solutions to differential equations? Given a second order differential equation and two particular solutions y1 and y2, what is the best way to find the general solution? i.e variation of parameters or something else

Above is the only thing I'm unsure about! Does the hermitian conjugate of the include the constant or not? Other than that I think I've solved the problem? Thanks

Hi everyoneI have been give a matrix operator and asked to find the eigen values, I have done so and then I was given a state |ψ> of some particle. The part I'm struggling with is it then asks for <H>, the expectation value of the matrix operator. It's a 3x3 matrix also. I've tried using the...

I was over complicating things little bit I think, and in the process confused myself :)Thank you for your help though :)

Never mind Mr. Walter Lewin has solved my issue

I have been studying electromagnetism this year and we have spoken about Faradays law of electromagnetic induction and eventually how the emf induced is equal to the negative time rate of change of magnetic flux I noticed however that all examples include a time varying magnetic field, which...

Ah I see it! I have dV(x)/dt Rather than what I should have which is dV(x)/dx

I'm not sure I follow what you are saying?

So potential between that a and 0 is not 0?

Ok fair enough! I'm using u phone so I find it much better to post photographs

Hi all, I'm not 100% sure this belongs in this topic but it was a problem I was given in a quantum mechanics lecture so here goes, sorry if I am wrong.Anyway I was given a hamiltonian H= T+VWhere T is kinetic energy and av is potential, and asked to use dH/dt= 0 to find an analogy between...

That makes sense, I was mixing up the formula I was using:( Anyways thanks, I also found I good way to find amplitude... A2/A1 = 2k1/ k1+ k2 And calculated each term according to k= 2π/λ
