Using LaTeX, I am attempting to write a single-variable calculus textbook that gives the reader an understanding of calculus and its applications without a lot of the fluff I have seen in many other textbooks (I should mention that I am a rising high school senior going into multivariable calculus this coming year). In my opinion, if a student is impressed by the high quality, ease of understanding, and straightforwardness of the textbook, then with good teaching, the student would successfully learn the material as opposed to memorizing facts.
I'm not just writing a textbook. I also plan to hold a class online through Google Hangouts or a similar medium that goes through the textbook as well as practice exercises.
I have already assembled a group of friends to go through the textbook as I write it. These people range from people who have not yet started AP Calculus AB but were decent in Pre-Calculus (who will read it for understandability), people between Calculus AB and BC (who will read it to make sure I haven't overcomplicated it), and people who have completed Calculus BC and above (who will read it for correctness and suggestions on additions/deletions).
Does the idea for this class sound viable? Also, how would you recommend I maintain the organization of the documents for each chapter/lesson?
