¥ Printing Suggestions for
Typed Files
I
recommend two-page-to-a-side and/or double-sided printing to save paper. If the
typed print is too small, try something like Page Setup: Scale: 110%, unless
print gets cut off (100% may be better for handwritten notes). Color printing
is nice, but B&W printing is cheaper.
These are pdf
files. You can get the free Adobe Reader at http://www.adobe.com.

¥ Class Notes
¥ Many students
benefit from printing the notes
for a lecture beforehand, reviewing
them, and commenting on them in
class.
¥ You may want to
take personalized Òsketch notesÓ in class.
For Òattribution,Ó
simply mention my name and/or web URL somewhere if youÕre using huge chunks of
the notes. I simply want due credit.

CORRECTION: On 3.4/3.5, #6c, assume
that x > 1/4. Otherwise, if we
relax that assumption, the Power Rule requires use of absolute value for |4x-1|, and -13/2 is another solution. Even Mathematica ignores -13/2.
