Homework Statement
Is the commutator of x and any function of x zero?
Homework Equations
Taylor's theorem allows such a function to be expanded into polynomials, so that [f(x),x] may be expanded into terms of [x^n,x], which are all zero. Hence, f(x) and x commute.

In Griffiths' Introduction to Quantum Mechanics problem 2.22 as well as 6.7, I used substitution to complete an integral. The original integral had limits from negative infinity to positive infinity. For my substitution, I had a complex constant term added to the original...
Griffiths says that charge will continue to flow to the surface of the conductor until the cancellation of the field is complete. However, if there are not enough charges (which may be the case in a real conductor), the total cancellation may not be complete, resulting in a net E field inside...
