Feb 19, 2021 at 12:38 comment added Emilio Pisanty That said, please take a minute to read our guidelines for homework and exercise questions as well as check-my-work questions. We intend our questions to be potentially useful to a broader set of users than just the one asking, and we prefer conceptual questions over those just asking for a specific computation.
Feb 19, 2021 at 12:37 comment added Emilio Pisanty Welcome to Physics Stack Exchange! Note that we use MathJax to typeset mathematics; you can find a good tutorial here. I've transcribed your image, but in future you should typeset it yourself. (As a good starting point, you can often copy-paste directly from Wikipedia and then trim the results.)
