The first video "Differentiation is Linear " comes from one of my own personal questions I had when I took Calculus I. I never quite got the answer until I got to Linear Algebra, so I introduce the Linear Algebra definition of Linear to make sense of this statement for someone who has just taken Calculus I.
Also, if you saw my earlier videos, you might have noticed that the quality of my videos has improved some. Instead of my incredibly janky setup where I stream to Twitch and export to YouTube, I use the record setting on Open Broadcast Software, and only use it to record video. I record and edit the audio through Audacity. To edit the sound and video together, I was going to try to Blender, but I was running into some troubles, so I stuck with just using Microsoft Movie Maker, until I can find some more time to tackle a more complex video editing program. Unfortunately, I lost a lot a video quality during some process. I'll have to figure out where that happened and improve it for next time!
