Required Reading: A new Approach to Calculus
Throw those dusty calculus textbooks out because Cengage Learning’s “Brief Applied Calculus” rewrites how advanced math should be taught. Written by James Stewart and Daniel Clegg, there’s a 560-page textbook that emphasizes intuitive math and real world applications. There are also an enhanced ebook as well as online and video adjuncts to help teacher and student. You can read through Chapter 3, which goes over techniques of differentiation, for free.
