Last time: Wrapping up Section 7.1: the exponential function
Any questions on that?
Ramp up your basic calc skills (one thing to try is the Course companion web-site associated with textbook)
Let's now take a look at Section 7.2: inverse functions
Assignment: pp. 356-358, 1-7, 17, 18, 28, 30, 43, 44 (let's make
this one due Friday, 9/5)
Let me take this opportunity to re-emphasize that you're free to
stop by and discuss any homework problems that are causing you trouble;
furthermore, I'm happy to let you see the solutions manual (if you've
attempted problems, and are just frustrated!).
Why study inverse functions? For example:
Pollution
Forensics
Ballistics
What inverses do you know already?
Proof: using the definition of the inverse, and the chain rule.
Examples:
#8, p. 356
#9-16, p. 357
#20, p. 357
#22, p. 357
#31, p. 357
#33, p. 357
