Working on course notes for the crazy class I teach, and published chapter one (weeks 1 & 2) today. It is at https://www.softcover.io/read/bf34ea25/math_for_finance . Check it out while it is still full of typos and quirks!

Yep, buy my other book too. It is at https://leanpub.com/earthcalculusthebook. I like it, so maybe you will too.
