I came back to school after 20 years and was terrified of math. You have helped me through every course in the last 3 years. Thank you so much for what you do. You should have far more subscribers. I guarantee you've helped more people than any "influencer" has. I'm actually pretty good at math now! Thank you!

How do you solve this analytically? Like we're not always going to be able to see the graph. I have looked through every single bit of content on your channel and I can't find any examples where you don't use a graph.
