Updated 26 December 2013.
I am rarely asked what students should do to prepare for this class,
although that is a question that should be asked.
My answer is as follows:

If you are new to my class, or got away with using a crappy calculator
like the TI30Xa last semester, read these comments on the
calculators you are allowed to use.
You will need to do complicated calculations involving scientific notation on the
first exam. Get an appropriate calculator immediately so you can use it
on all of the homework leading up to Exam 1.
I will not allow the TI83 in PHY2049, although you can use it in the lab.
(On lab exams, you will have to wait for it to be cleared before you can start
the test.) You should only use your physics calculator for physics homework!

Except for the what is listed under items 3 and 4 below, you should
already be ready for this class. That is, you should still know
the basic equations of motion, how to use a freebody diagram to solve
mechanics problems, how to apply conservation of energy, how to work
with vectors (including both the dot and cross product), how to evaluate
derivatives with the chain rule, the fundamental theorem of integral
calculus, and how to set up basic application integrals. If not, you need
to work on Learning because your engineering professors will assume that you
did not waste your time and money taking calculus and physics. Some
engineering classes will test you on that material during the first few
weeks of your first semester classes. For reference,
here is the link to a pdf file
providing a onepage summary of key 2048 ideas for 2049 students.
That said, many of you need to prepare for your calculus class
so you don't fall behind in physics while trying to keep up in calculus.

Unless you are the rare student who knows how to find the area and
volume of a cylinder or sphere without having to look it up, put a
major effort into learning all of the geometry material in the
appendix to our textbook (pg. A1). This is also important for MAC2313.
While you are there, reviewing the summary of trig and complex numbers
(and everything else in Appendix A) would be a good idea.

Read my comments on the
calculus requirements
for my physics courses. They are minimal, but significantly
higher than was the case in PHY2048. If you did not take
the "early transcendental" MAC2311 at TCC, you will need to learn
the derivatives and integrals related to the transcendental functions
e^{x} and ln(x), among others, for both physics and calculus.
More importantly, I expect you to have a fairly deep
conceptual understanding of integral calculus and
the Fundamental Theorem, or develop it fairly quickly.
I will also expect you to set up applications involving integrals
in one variable, a topic that is normally introduced at the end of MAC2311
in some sections at TCC and then covered in great detail at the start
of MAC2312 in every class. (It is done in detail at the end of MAC2311 at
colleges that use the "late transcendental" curriculum).
I will show, in detail, how to set up the integrand for application
problems involving electric fields and electric potentials for those who
are not taking MAC2312 or forgot all of it.

Reread Chapter 3 of Wolfson, which is mostly review of
the basic properties of vectors. You can also review
that same material, as well as "dot" and "cross" products, in
Chapter 12 (sometimes 13) of your calculus book. You already sortof learned
that material in PHY2048, so I will not go over it again in much detail
except in the process of working examples to help you become expert at it if
you are not currently taking MAC2313.
You will notice that threedimensional problems appear in the first chapter
we cover this semester (Chapter 20) and just about everywhere else,
and this is also the case in MAC2313. One early problem, one I usually do
on the first day of class, is similar to one we did in Chapter 8 (gravity)
in PHY2048 so this should not be entirely new to you.

If you will be taking MAC2312, prepare by studying as if you
were going to take the MAC2311 final exam on the first day of classes.
Some of you will not succeed in Calc II unless you know more of
Calc I than you did when you took the final, so put particular emphasis
on any topic you think you might have missed on the final exam.
Partly for this reason, you should consider your course load very
carefully, particularly if you got a C in MAC2311 and/or struggled
to barely pass PHY2048.
Collegelevel math classes pick up where the previous one left off,
and Calc II is (most students agree) somewhat harder than Calc I.
My short list of things to know would include the deriviatives
of every function that has a key on your calculator (including the
inverse tangent and inverse sine functions), the chain rule,
and about a halfdozen of the basic identities (pythagorean, double angle,
half angle) from trigonometry. If your MAC2311 class had an "exit" or
"gate" exam, you probably know the derivatives I am talking about.

If you will be taking MAC2313, prepare by studying the material
on vectors in 3space in Chapter 12 (??) of Stewart's calculus book.
That is the usual start point in that course, where they go into
much greater depth than we do in either PHY2048 or PHY2049.
You might also review the onedimensional work integral from
the applications section (Chapter 6?) in MAC2311, because that topic
will be revisited (in 3space) later in MAC2313 and used in
PHY2049 at the conceptual level.

Read my Study Suggestions
and review the additional comments on program planning and your
workload this semester that are at the end of this page.
Please read my
advising notes on physics.
This comment is particularly applicable to new students, who should
also review what is required for admission to the college they plan
to enter after graduating from TCC. Be sure you are prepared to meet
all of the requirements to start your major as a junior at the
end of this semester or worked out a plan with an advisor at your
future school so you will be ready by the end of next semester.
If you do not have a work schedule that includes
20+ hours set aside throughout the week to study
for just your physics and calculus classes, you should reconsider
taking both calculus and PHY2049 at the same time. Those of you who
have passed Calc I and PHY2048 have a better idea how much work is ahead,
but you need to realize that Calc II is harder than Calc I. On the
other hand, Calc III is, in my opinion, a little bit easier than Calc II
and fits in well with PHY2049.
Future engineering majors and science majors should pay careful attention
to the requirements for their transfer school. A few examples:
The University of Florida "tracks" PHY2049, so you must pass it with a
C with at most two attempts, including withdrawals.
Science majors (such as physics, chemistry, computer science, biochem)
at Florida State can have no more than a total of 5 failing grades in
math or science classes required for their major, including both those
taken at a CC and those taken at FSU. I believe a similar rule applies
to classes taken by Engineering majors AFTER they transfer, so be sure
you know the risks if you are a transient student enrolling from FSU.
