You can always do more homework problems!
You may need to practise the material
if you want to remember it
for the final exam,
a subsequent course, or the rest of your life.
If you bought MyMathLabPlus access
with your course textbook (or separately),
then you can find supplementary problems there;
see the MyMathLabPlus instructions.
(However, MyMathLab is *not required* for this section.)
