Calculus Book

This book is amazing. And I got it for free from the MIT website, where I found it while watching some videos trying to brush up on polar coordinates and hyperbolic integrals (Don't ask why... I am such a geek... =))

After I worked through my problem, I circled back and began reading the book. And I was amazed at the clarity of the text. It is officially the second best calculus textbook I've seen -- the best was a Dover book that I found in college by Morris Klein. Strang makes the concepts behind the calculus intuitively clear, and doesn't get bogged down in "proofs."

Which, after all, makes sense. Since Newton and Leibniz were trying to solve a physical problem -- the instantaneous velocity of an accelerating object -- when they developed the calculus.

I think every high school and college should use this text. Instead of the "new and improved" texts weighing in at 2000 pages and costing $250... But I digress...
