Professor Leonard I can't thank you enough... Through this quarantine I've learned calculus 3 with your videos and had lots of fun too, because I'm a dork, and because of your awesome sense of humour and the most important of all: an amazing teaching skill. Again, I've appreciated a whole lot your commitment to uploading such high quality math and physics videos that when I'm economically capable I'm going to give back to you through your patreon! Thanks again, you have given me a great example to what a great teacher is such that when I become a math teacher myself ( if hopefully my dream comes true) I'm going to take great inspiration from you! Greetings from Italy.- Giacomo

This was a much needed video to serve as a checkpoint for what we learnt so far. Granted it is very basic vs the real world but at least the general idea serves as a good prelude of whats to come as we advance further.

Professor Leonard, I took the last course of Calculus the previous summer which is CALC3. I've been watching your playlists from DAY 1. I just want to thank you because I've been always hated math but for the first time, I got an A in CALC3. Thank you very much. You deserve the whole world! Stay safe 🌻

Professor Leonard, thank you for explaining the Applications of Quadratics Functions and its impact on real life economics. Revenue is a huge application that involves Quadratics equations.

I hope to start learning differential equations soon! I’m excited. I just need to get through calculus first at a pace that I can learn everything thoroughly.

For anyone curious, the vertex x coordinate you get for the last example is 62, 500. Therefore, h(62, 500) is 31, 250.
