An interesting discussion over on HN was going down today about online resources for learning Physics. Some good links came from that. The calculus notes here: http://tutorial.math.lamar.edu/ and a very comprehensive collection of physics links: http://www.staff.science.uu.nl/~hooft101/theorist.html it is really worth taking a look at the resources linked to from there.
I will close on a personal recommendation from 1914. Calculus Made Easy by Silvanus P. Thompson http://www.gutenberg.org/files/33283/33283-pdf.pdf
