derivation

$H_{\psi }=E_{\psi }$

1-D: $E_{TOTAL}\psi (x)=E_{k}\psi (x)+V(x)\psi(x)=-\frac{h^{2}}{8\pi ^{2}m}\frac{d^{2}\psi(x)}{dx^{2}}+V(x)\psi(x)$

derivation

is it important to know how to derive all of these different equations?

Re: derivation

Having the equation sheet on the tests and quizzes, I would think that it is not too important to know how to derive the equations. There are many equations that are extremely complicated and time consuming to prove as well. I think that if Dr. Lavelle has proved the equation on the board during a lecture, then it would be good to try and learn to prove yourself as well.

I think it's good to know how to derive the equations discussed in lecture, just to be on the safe side incase they come up on an exam!

Re: derivation

I don't think we would be given problems where we have to derive the equations (especially since we are given a formula sheet for exams), but knowing the general basis of the derivation is definitely helpful in understanding the main concepts behind the equation. I would know how each variable relates to each other and why each variable is present in the question in case if we ever get asked any conceptual equations!

Re: derivation

Do we know where he gets his equation sheets so we can know what equations will be given on the test? Such as prefixes, percent yield, etc.

Re: derivation

Yupp, his constants and equations sheet can be found on his website or here
