explicitly given in the book, but not informal arguments such as “this is 1oig and that is
big, so their product is big”). Explicitly mention those theorems and limit laws that you
use. (If you use limit laws, you may give them by name instead of by number, and you do
not need to explicitly justify steps from high—school algebra.) 3. (11 points) Find the following derivatives: d 7 g 5_ 3_ i cscx
