- Schrodinger Eq
Hi, I'm trying to prove a wave equation of particle in a box situation.
In many solutions, they used a equation like Eq = Asin(kx)+Bcos(kx).
Instead, I want to prove using Eq = Aexp(ikx) + Bexp(-ikx).
So, this is my solution.
However, the original (well-known) solution is without i. (psi = sqrt(2/L) sin(n pi x/L)
Is two wave function is same? or is there any error in my solution?
Sorry for my bad English. I'm new to here and looking forward to get help.
THANKS!
