Lecture 2, Wilson

(The exam, like other math files, is in Adobe PDF format. I have noticed that
when reading them with some old versions of the Adobe Acrobat Reader program you
may see lines across the page or boxes around some parts of a page. If you are
seeing those you might want to update your version of the program, free at www.adobe.com.)

The final exam is 7:25-9:25 PM on Tuesday, December 20. Students in James
Hunter's discussion sections will take the exam in room 22 of Ingraham Hall, all
others in room B10 of Ingraham Hall.

There will be 10 problems on the final, 3 of which will be specific to Chapter
17. You are allowed to bring notes on up to 3 index cards (no larger than
4"x6") and you are allowed to use a calculator.

Concerning the first midterm exam:
Here is a set of answers to the exam. (The early,
alternate, exam for those with conflicts, was slightly different.)
In the email I sent out re the first exam, there was a URL for my old
calculus exams. To simplify things, HERE
is a link directly to the calculus exam page.

9/16/05: Several people have asked me to post the Maple code I used in class
last Wednesday. That produced an animated plot traversing a curve, showing the
position, velocity, and acceleration vectors. HERE is a
link to a copy of that file: If you click on it you will probably get the option
to save it to a file on your computer, or on a PC you can right-click on it and
choose "Save Target as ..." to save it to your computer.
I have posted here the version I used: It can be improved a lot. In
particular it defines the position function r(t) and then separately defines the
velocity and acceleration, using what we know to be the right derivatives,
rather than having Maple do the differentiating. When I get a chance I will
improve that: Then one could easily change the curve without having to change
also the velocity and acceleration calculations.
OK, a few hours later: I have changed this so it does the
differentiations itself. So now you can change the function r(t) to
something other than the helix I used in class and all will work fine...
Except that it still will try to plot it in the same window, so if you use a
function that goes off somewhere else you may not see much. But, for example you
can change the line defining r(t) to
r := t->[cos(t),t, sin(t)];
and the you will have a helix spiraling the opposite direction, or to
r := t->[sin(log(t+1)),t, cos(t)];
and see what you get then!

From the beginning of the semester:
Math 234 is the third semester in UW-Madison's main calculus sequence. For
the most part it takes concepts (derivatives, integrals, graphing and slopes,
etc.) that have been studied in the first two semesters and moves them out of
the plane: Previously a function was typically something like y=f(x)
where x and y each represent a single real number. We will now
allow them to have multiple components, so that x or y might
represent a point in space, or a vector having direction as well as magnitude.

In connection with this course I have agreed to be part of the "Maple
Adoption Program" arranged by the computer software company Maplesoft.
Maple (presently version 9.5) is a powerful program in the category usually
called Computer Algebra Systems. Maple and its competitors Mathematica and
Matlab surely dominate this market, although I do not have statistical data on
market share. I, personally, have been using the various Maple versions for many
years now, but I also have used and occasionally still use those competitors. I
will be using Maple in class for demonstrations, and frequently I also use it
when working out exam problems, to check my answers, or to produce pictures to
include in exams or class handouts.
If you are going on in the sciences, including the social sciences, you will
quite probably want and even need to use software like this at some point. Each
of those competing programs has its own particular advantages: I find Maple most
resembles the way that mathematics and science and engineering classes express
and use mathematics, so it seems easier to use in connection with what you learn
in classes. In addition it is exactly what I will be using in class.
You are in no way required to buy or even to use Maple for this course. (It
is available on computers in several campus laboratories, if you want to try it
out without buying.) But participation in the Maple Adoption Program does make
it available to you at a reduced rate. You can purchase a copy of Maple 9.5 Student Edition
at a reduced price of $75 if you download it while registered for this course:
Here is the information you need to take advantage of that:

The student edition of Maple is also available for sale locally, and buying it
that way gets you a CD rather than the download, but it is significantly more
expensive.
