If you didn’t cover derivatives and the chain rule in high school, or have forgotten this stuff, that’s OK - we’re here to help! Be sure to watch the 3blue1brown ‘essence of calculus’ series, and the relevant bits of Khan Academy. Ask here for help with absolutely anything to do with calculus that’s mentioned in our course, even if you haven’t finished (or started!) those videos.
When you say ‘the relevant bits of Khan Academy’, which sections specifically do you mean? Or is that dependent on my understanding of things?
The ‘Differential Calculus’ section seems probably to be pretty good value for money, covering both derivatives and the chain rule, which are maybe the core concepts I need to understand?
