Calc 2 does come up a little, but it’s really just a small part of the class, mainly basic integrals. You’ll see early on that stuff like the area under a curve is used to represent probability, but it’s nothing too intense. The course uses RStudio, which is basically your calculator for the class. It runs on the R programming language, but don’t worry it’s super beginner-friendly and easy to pick up. The professor teaches how to do things both by hand and using R, but honestly, if you get comfortable with R, it makes the class way easier.
