Maple
- The World's First Fully Integrated Analytical Computation System
Maple
demonstrations for teaching multivariable calculus,
by Fr. Mike May, St. Louis University
At
Saint Louis University, we are using graphing
calculators as the primary technology in teaching
our introductory calculus courses.
However, as students advance to multivariable
calculus, the need to visualize in 3 dimensions
makes Maple far more effective than graphing
calculators. Our Calculus III course is being
taught in a computer classroom where the students
have access to Maple.
The
strategy I have used for bringing Maple into
the classroom is to introduce it through carefully
designed worksheets, which I use as:
Lecture
aids with the instructor running the worksheet
with a projection system.
Handouts
for the students
Lab
assignment that the class will start together
as a substitute for a lecture.
Supplemental homework assignments.
These
worksheets include a significant amount of exploratory
text and exercises. The exercises ask the student
to repeat the examples in the worksheets with
minor modification. I do not expect them to
produce the code, but rather to copy and modify
a code template, focusing on the results of
the problems.
A
fast handout explaining the syntax for
dot and cross product in Maple. The intent
is to show the students how to use Maple
to check their work with vector computations.
Visualizing
the definition that a function is differentiable
at a point if the graph near the point
is locally approximated by the tangent
plane. The definition is used to understand
the corresponding delta-epsilon definition.
Demonstrates
for the students the Maple commands needed
to do integration. It seems useful in
this chapter where many of the problems
reduce to "and finish by evaluating the
two or three integrals."
How
to plot in coordinate systems other than
Cartesian. It also shows how to combine
objects described in different coordinate
systems on a single plot.
The
Riemann sum definition of double integrals.
It follows the usual pattern of the course
by reviewing the definitions in the one
variable case, then generalizing.
This
worksheet was done by the students in
class. It looks at setting up integrals
in polar coordinates and switching between
rectangular and polar coordinates.
Parameterizing
planetary motion under gravity. This is
a demonstration worksheet and was done
after Chapter 17. It solves for planetary
motion with a flow line solution of a
vector field in 4 dimensions. The orbits
of Mars and Halley's comet are studied
as examples.
