Welcome to Precalc!

Hi,
The first half of this course is about basic functions and building new ones
by first addition and subtraction and multiplication by a constant.
Then, we build new functions by multiplying and dividing functions then taking
composites and inverses.
Then, we build new functions by either making a function grow by either
repeated addition or repeated multiplication and consider their uses.
Then, we spend the last half of the semester studying and using trig functions.
Please read: Things You Should Know About How This Course Is Run
and decide if this is really the course you wish.
The page "Assignments, Quizzes, ..., Grading ... might also help you to make that decision.

Have a wonderful semester, A²
