Homework Statement
Derive the momentum for a charged particle going through matter.
Homework Equations
None.
The Attempt at a Solution
I understand the derivation but there's one step I am not clear about, and I'm probably being really stupid but this:
if the -infinity term is squared then doesn't it become positive and the sum equal zero?
Thanks for any advice.
