Found an answer on wikipedia:
There is another character, the minus-plus sign (∓) which is seen less often. It is generally used in conjunction with the "±" sign, in such expressions as "x ± y ∓ z", which can be interpreted as meaning "x + y − z" or/and "x − y + z", but not "x + y + z" nor "x −...
I'm studying for a quantum exam and there is this symbol that looks like an inverted plus minus but the minus is attached to the plus...
kind of like
_
+ but attached.
in context:
"x ± vt = constant or x = (-/+) + constant."
Thanks for any speedy help!
Calculate d<p>/dt Answer: d<p>/dt = <-dV/dx>
generally speaking (I believe) you need to use scrodinger's equation (both of dphi/dt and dphi*/dt)
and the expectation value of momentum:
<p> = -i*h_bar * integral (phi* * dphi/dx) dx.
I would say that the way I used Cramster was just short of...
