You Already Know Calculus
for inventors and other curious folk(zeroeth draft--2011)
In which I demonstrate with easy arithmetic that calculus should be easy but is taught to be hard.
Unfinished labor of unrequited love, available now for an infinitesimally small price. If you don't think this is the best easy calculus book you've ever read, just return the electronic file for a full refund of the whole cost!
