In this post, I’ll be going through how to solve another integral, this time using trig-substitution. As I mentioned in my u-substitution post, I’m writing this post as a reference for a future video/post about aligning torque, and I specifically needed to solve this integral. If you would like a more neatly formatted document, you can find the attached PDF at the end of the post. The integral we will be solving can be seen below.
