Ok. So if A=B then from the second equation we have that A=B=0 so we don't want that so we must have coska=0. So this gives the solutions we want. I also worked out from the determinant and we get sinka*coska=0 so this is what we want. Thank you very much Does anyone know about the extension...

Thats the problem I don't know though. I am not sure why coska=0. I just used the equation in your post 7. Thats why I asked what if that is enough of a reasoning or is there a way to conclude that cos ka=0?

I haven't hear of node and antinode before so although I understand that we have two sets of solutions I'm not sure if that is sufficient to just say that those are the solutions. Is my reasoning correct to write down that k=n*pi/2a. Is it just a result to say that there is an antinode,and how...

I am not sure that I know exactly what you mean but this is what i think. Do the 2 equations mean that sin and cos have to be zero as u said. So what if i have k=npi/2a for even for sin and k=npi/2a for odd for the cos? Im not sure what u mean I am missing half of the solutions. Thank...

Yes you are right there. But then I have the case that tan(ka)=-tan(Ka) and we have that K tends to k. so then we solve sin(ka)=0 which is k=n*pi/a. But this does not satisfy the energy levels of the infinite well which is E=((h*pi)^2/8ma^2)*n^2

IF B=0 then its either A=0 or sin(ka)=0 or cos(ka)=0 as I see it from equations 1 and two.. I will probably scan my work and if I can figure out how to post it on here I will..

55 views and no1 can help or suggest something? PLEASE let me know if you want me to scan the question and my work I can do that. Thats the only way to include all my work done on here.

If any of the people that looked at the problem need any information please let me know. Any feedback is helpful.

I have a very similar problem with yours but from -a to a. So if you have any idea or something we could help each other

SPECIFICALLY SEE POST 8 AND AFTER PLEASE Hi so that I can get the help for the specific problem I am working on I will set the question up and include all the steps that I can get and work out. The end question will be about quantized energy levels. This is for a maths module. I am...
