Getting a copy of Stroll

A Stroll through Calculus covers many of the concepts of calculus in an informal way with little more than intermediate algebra (and later, some trig). It's an attempt to help people understand what's going on without intimidating proofs or formalities, because the basic notions of calculus are both straightforward and elegant.

Anyone who wants to obtain a copy of A Stroll through Calculus can use this direct link to the publisher:

https://store.cognella.com/25177

If you need any help with ordering from Cognella, feel free to email orders@cognella.com or call 800.200.3908 ext. 503.

Stroll is listed as a required textbook on ARC's online Follett bookstore pages for Math 402 and Math 499, but copies will be on reserve in the library so you don't have to purchase a copy. If you choose to buy a copy, you will get a better price from Cognella than from Follett (or Amazon), so use the provided Cognella link.

Math 420 (spring 2024): Quiz solutions III

The third exercise in Quiz 16 contained a serious typo, so I'm giving everyone full credit for #3 and grading the quiz only on the basis of the first two problems. Rewrite the problem as (D − 5)3y = 0 if you want to have more fun.
