(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Whilst revising the Biot-Savart law, I came across the result:

for the magnetic field due to a long straight wire. I understand that this can be found by integrating the Biot-Savart equation over the length of the wire, however after attempting the integral myself and looking at the integration in my notes I find myself unable to understand how to come to the result.

2. Relevant equations

3. The attempt at a solution

Outlined above. Any help will be appreciated, thank you.
