## Using Shrodinger's Equation

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

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

### Using Shrodinger's Equation

Hey there,

For the upcoming quantum test (ch1+2) do we need to know how to use/derive shrodinger's wave equation? I understand the general conclusions of it, as well as how it applies to the quantum unit (and quantum numbers), but every sample problem in the book seems to be centered on the complex math behind the equation, which I am very confused about. Do we need to know this for the test?

I'm pretty sure my TA said we would only need to understand the conclusions and applications. I don't think we need to know the derivation.

### Re: Using Shrodinger's Equation

I had the same exact question. I was unsure of how to apply the equation for math problems and did not understand how we were going to be asked this in the test. I am guessing the questions about it will be like the conceptual questions we had on the past two tests.

I am also confused on how to apply this equation in mathematical problems, but because he did not include any in the assigned problems for The Quantum World I don't think we need to know how to use it. We should understand how the equation describes an electron as a wave since it has duality as a particle and a wave.

Hello!
In my discussion my TA said you would have to know how to apply the equation using the concepts but not mathematically derive the equation! Hope that helps!
