Thank you clamtrox. I am very rusty about the definition of continuity and differentiability, even I went back to my calc textbook, I still cannot figure out what I should do. Can you tell me what's wrong with my reasoning?

Homework Equations
The Attempt at a Solution
a, c are right because f(c) is continuous.
b, d are right because f'(c) is differentiable over the interval
I am not sure about e. Can anyone explain to me?
Homework Statement
An electron is confined within a three-dimentional cubic region the size of an atom where L = 200 pm.
a) write a wave equation for the electron
b) wirte a general wave function for the possbile states of the electorn. List any quantum numbers and their possible values...
Thanks.
I was doing a problem: An electron is confined within a three-dimentional cubic region the
size of an atom where L = 200 pm.
and I remembered somehow, my teacher gave me these equation
do they work in such condition?
I have learned time-independent schrodinger equation only from my textbook.
I know Eψ(x) = - hbar^2 / 2m ψ''(x) + Uψ(x)
and ψ(x) = Asinkx + B coskx
what if it's three dimention?
do I do Eψ(x, y, z) = - hbar^2 / 2m ψ''(x, y, z) + Uψ(x, y, z) ?
and what is the wave equation supposed to be?
I can define +x and +v to the right side and the 500MeV photon is heading to the right while the 200MeV photon is heading to the left. The final momentum of the particle P will have positive value, which indicates that it's moving toward the right. This is definitely what I should think of in...
Homework Statement
Consider the one dimensional wave funciton give below.
a) Draw a graph of the wave function for the region defined.
b) Determine the value of the normalization constant
c) what is the probability of finding the particle between x = 0 and x = a/2
d) show that the wave function...
I see my problem after a nice sleep lol.
I originally thought all energy from photon goes into creating the particle P, but because there's momentum left so that assumption was wrong and I cannnot use E = mc^2 where E is 700 MeV and thus m = 700MeV/c^2.
