16-10 Summary
The following notes are for the Calculus D (SDSU Math 252)
classes I teach at Torrey Pines High School. I wrote and
modified these notes over several semesters. The
explanations are my own; however, I borrowed several
examples and diagrams from the textbooks* my classes used
while I taught the course. Over time, I have changed some
examples and have forgotten which ones came from which
sources. Also, I have chosen to keep the notes in my own
handwriting rather than type to maintain their informality
and to avoid the tedious task of typing so many formulas,
equations, and diagrams. These notes are free for use by my
current and former students. If other calculus students and
teachers find these notes useful, I would be happy to know
that my work was helpful. - Abby Brown
