You forgot to attach the tools and the one you attached is solved example for q1 method not for q2. I assume that the tools means standard differentiation formulas instead of first principle method ?

Hi Alan, the “tools available in Chapter 3” are examples 3.4 and 3.5 in the document attached. Thank you!

Name your textbook with author, it can't be! The examples are based on first principle! Which is definitely not a tool since it is basic definition of derivative
