Considering how many fools can calculate, it is surprising that it should be thought either a difficult or a tedious task for any other fool to learn how to master the same tricks… Being myself a remarkably stupid fellow, I have had to unteach myself the difficulties, and now beg to present to my fellow fools the parts that are not hard. Master these thoroughly, and the rest will follow. What one fool can do, another can.
For years, I have recommended Calculus Made Easy as summer reading (and future reference) for high school or college students headed into a calculus course — and for the parents of those students, who may have studied calculus in ages past and now need to dredge out the dust bunnies of memory so they can help with homework.
The original book (second edition) is now out of copyright and available for free online:
- Calculus Made Easy [pdf, 11.4 MB]
[Hat tip to Sam and Michael for finding the Scribd version, which set me off searching for a clearer copy.]
Denise Gaskins' Let's Play Math 
this is indeed a cool find.
michael mentioned it in
_god_plays_dice_ recently too.
free classics online… whoo-hoo!
i named my new post
after the “at play!” carny.
(and sent the link to tom d
for the next edition). whee!
You are my best friend today. ‘Nuff said.
I just recently started a blog about Mathematics where I am trying to help Mathematics students, providing some solutions on various topics, hope you will see and like it.
