To create a series or add a work to it, go to a "work" page.
The "Common Knowledge" section now includes a "Series" field.
The main feature for all these books is the solved problems.
Step-by-step, authors walk readers through coming up with solutions to exercises in their topic of choice.
I've been using MIT Open Courseware for single variable calculus (and will do the same for multivariable).
I fenced the parent post to Linear Algebra to not go too far away from the OP.
I started off with this but had to rewind to the UT class because I didn't have some of the fundamentals (e.g. I'm personally 15% through this, but enjoying it.
Linear Algebra Review PDF (Stanford CS229) Link: This is the set of Linear Algebra review materials they go over at the beginning of Stanford's machine learning class (CS229).
If you are like me, and working off an initial base of high school math, I would recommend the following (all free): Linear Algebra Foundations to Frontiers (UT Austin) Course: https://org/course/linear-algebra-foundations-to-fro... Good interactive HW exercises, very clear instruction and time-efficient.
