| Course Outline for Math 112 (August 25,
2003)
Math 112 is a difficult course to design because there are so many
important topics that one might cover, and one cannot cover them all.
The UCC has heard about wide variations in content of Math 112 during
the
last several semesters, and in a meeting of August 11, 2003 we discussed
what
needs to be in Math 112. Here is our consensus concerning topics
that
have sometimes appeared and sometimes have been skipped in recent Math
112 courses.
1) Differential equations must appear because this is the only place
in
the required curriculum that our students encounter the subject. (At
least
slope fields and Euler's method, separable equations, and exponential
growth should be covered; Sebastian Schreiber will propose a
Maple lab on
Euler's method that could be added, even though it will not be part
of
the student lab packet.)
2) Sequences and series (at least up to Taylor's theorem with remainder).
This is the only required course in which majors in the applied track
or
teaching track will see this topic.
3) Approximate integration (Cover at least the trapezoid rule with use
of
the error estimate. However, there is some nice geometry that helps
explain the relation between the estimates provided by the trapezoid
and
midpoint rules in certain circumstances and, time permitting, that
would
justify covering both. Simpson's rule is optional.)
4) As you know, Math 112 is a course that awards GER1 credit.
To do that
it must include numerical calculations, some explanation of why the
numerical calculations work, and a discussion of applications that
would
be recognized as such to an educated outsider. We have no problem
in
meeting the first two of these criteria, but we need to be careful
not to
overlook the third.
5) What, then, should be covered in Math 112? The following list
is based
on the fourth edition of Stewart's "Calculus with Early Transcendentals"
and will need to be updated when we move to the fifth edition.
Review Chapter 5 (Introduction to integration). Students should have
seen some of this material (up to 5.5), but that was three months ago
and they need a review at the start of Math 112. Integration
by
substitution is likely to be an area where they are particularly weak.
The section on logarithms and integrals is optional.
Chapter 6 (Applications): Cover areas between curves, volumes of rotation
by disks and washers, and work problems. Skip cylindrical shells.
Chapter 7 (Integration techniques): Sections 7.1 to 7.5, plus 7.7
(approximate integration, including some work with error bounds) and
7.8.
Chapter 8 (More applications): Cover arc length (8.1) and hydrostatic
pressure (in 8.3); skip surface of revolution and center of mass.
Chapter 9 (Differential equations): Modeling, direction fields and
Euler's method, separable equations, exponential growth, and logistic
models. Systems with two interacting populations would also be
nice, but
might not fit.
Chapter 11 (Sequences and Series): Essentially all of this chapter (11.1
to 11.10 with 11.11 optional) should be covered.
Chapter 10 (Parametric equations and polar coordinates) should be the
last material covered in the course and should be the first to be omitted
under time pressure. We would be very surprised it you can fit
this
material into Math 112.
