Sorry if this is the wrong thread to post this sort of question in, but I assumed it would be proper given by the fact that my question pertains to learning calculus, and thus should be relevant to the calculus forum. Anywho.... I just recently started my study of calculus and have come across a plethora of different books of different qualities. Right now, the best one for me has proved to be "The Calculus Lifesaver", as it explains the fundamentals LUCIDLY, without over complicating simple concepts like basically every textbook does. I'm also using one of those overcomplicated textbooks for the exercises to get some practice in, but aside from that, they seem to be useless. I have recently heard about, and now browsed through, an engineering book called "Engineering Mathematics" by Stroud, and it seems to cover basically everything that is needed for the first three semesters of calculus (at least it seems that way to me), and since I'm trying to self-study for AP Calculus BC, it seems to be of proper breadth and scope. I just want to know what people think of using an Engineering book to self-study calculus. This is not to say that I wont occasionally use other references, but rather that this one would be my main form of learning. Would anyone recommend doing this? Or would I be missing something that a traditional Calculus textbook would have that an Engineering one wouldn't? Forgive the lengthy post, thank you for reading; and thank you for future feedback.
