Why this is not going to work:
>half the posts are going to be pretentious idiots telling you that the book you're reading is shit, that you are a brainlet for needing help in calculus, or posting meme guides "required reading v2"
>there will be a dedicated shitposter in every thread spouting about how the real numbers are a sham, or something of the like
>unlike in reading literature (casual books, I assume in your /lit/ threads), you really require to put your full attention, parse through the text several times, have thinking time, have working time where you do exercises or try to prove theorems, going back and forth frequently
>/sci/ is a slower board than /lit/
I'm not saying you shouldn't try of course, I've seen several people trying these threads across the years, although few if any worked out. I think, mostly, is that those threads were pretty ambitious, attempting for example, reading the Landau mechanics book which is graduate level. If you're doing a relatively simple subject like intro calculus, you're going to have more chance surely. However, if you were to attempt this, then I will say that Stewart really is a meme book that can easily (and should) be done on your own time. It'd be like doing a /lit/ thread on Winnie the Pooh, and ultimately a waste of time.
As such, I would suggest as the first anon said, to do either one of those books, since they are deeper and more rigorous, and actually do capture the essence of calculus, while Stewart is more of a "techniques for scientists and engineers" type of book.
