I've been thinking about this for around 7 months now, which is way too much; Munkres seems like the "typical" introduction to topology book (kind of like how Griffiths is the "typical" E&M text), and various people (from the reviews over at Amazon) make it seem like it is an undergraduate level...

What introductory calculus textbook do you recommend? Is Spivak's book good or is it too hard? What about Ron Larson's?

I did not post this on the homework forum because they required to use the template. First, I have been using the "Known____Unknown______Equations" format; however, I feel this is not organized well enough for me. Then, I tried "Variables____Components_______________Equations" format. Do...
