Again, IB Math Calculus freebie. It’s from D. A. Kouba‘s Calculus Class in UC Davis. The set features a comprehensive list of topics that include explanation, graphs, diagrams, and also practice problems with detailed steps and explanation. Very helpful!
Worrying about coming up math exam on solving derivatives, I started hunting down problems on internet for practice.
I’ve known that Wolfram provides a problem generator, but only available to pro plan subscribers. $3 a month for students is not that big of a deal, but right now I don’t have needs to use it frequently enough so that $3 is actually worth it, I’ll look for some other alternatives.
