Yes and yes.
I have a series on differential equations here: this is the latest post, might be a little advanced, but at the bottom, there's a list of tutorials at the bottom that goes from the beginning.
I have yet to transfer all of my YouTubes to DTube yet, but you'll find a playlist of integration tutorials with some that use trig substitution here: https://www.youtube.com/playlist?list=PL0YzbD4vPtxK3b8LJ8zZRd0W4kohoj0Jm
