I want to introduce calculus students to computer algebra systems (CAS) like Sage, Geogebra, and Wolfram Alpha in college Calculus 1 and 2. While I believe in the value of learning to do calculus by hand to a certain extent, I also don't want to pretend that we don't live in the 21st century. However, most textbooks I have seen that discuss CAS at any length mainly just list some examples where a CAS gets a wrong or unhelpful answer unless you know what you're doing. While this is undoubtedly an important point, I think it comes across as a sort of desultory and apologetic afterthought.
Moreover, I feel there are important skills that could be learned here, that could potentially transfer and outlast any content knowledge about calculus: how to use a computer as a tool, translating a problem into a form that a computer can understand and interpreting the answer, what a computer can and can't do, experimenting with a computer, using a computer to visualize an answer or a problem, and so on; in short, how to use a computer as an extension of your brain (rather than a replacement for it). Are there any textbooks or other resources out there that utilize CAS in such a way throughout a calculus 1 or 2 curriculum?
Note that I'm not talking so much about the teacher using a CAS to produce nice pictures or animations to illustrate a concept (although that's certainly a valid use), but about teaching the student to use a CAS in productive and creative ways. (This is related to this question, but it's both more general (being about all uses of CAS rather than just exploratory/experimental) and more specific (being particularly about calculus 1 and 2).)
