How to do Biot-Savart for Straight Wires with Ends

We have done some work already with Ampere's law for finding B-fields created by long wires, solenoids (with no ends) and toroids. But in reality wires have ends, and we must use the real thing, Biot-Savart, to get those magnetic fields. Check this out for finding the integral for a straight wire with ends.
