MATH 1501 Calculus I:
Maple Explorations
Here you will find a collection of Maple worksheets designed to help
you in your studies. The following online resourses were written with this
course in mind.
- An introductory tutorial
on using Maple in this course. This tutorial covers the
use of a few simple Maple commands that you will find very
useful in doing your homework for this course. It was
written expressly for this course.
-
Slopes, Tangent Lines, and Derivatives: This worksheet gives
animated visualization for the computation and role of a tangent
line. The worksheet
is appropriate at an early stage in a study of differential
calculus.
-
Reflections on Differentiation: This worksheet is
designed to introduce how to differentiate both functions and
expressions. The problem of finding extreme values of simple
functions is illustrated by using Fermat's Principle to find the
path of reflected light. Some fancier plotting capabilities and also
the equation solving ability of Maple are also introduced.
-
Solving Equations: This worksheet is about
continuity--the intermediate value property of continuous functions,
etc. Equations are solved using "bisection," regula falsi,
and Newton's method. This assignment help you understand the Maple
procedures.
-
Solving f(a) = b: The Method of Bisection: The Method of Bisection for
finding roots of an equation is not conceptually hard. It has two
especially good features: first, it is easily understood, and
second, it can provide initial guesses for methods which might
converge faster -- such as Newton's Method. We illustrate the method
and provide an example to show that a little care must be
taken.
-
Maple example for a Max-Min problem.
This example was contributed by the student Roger Lang.
-
Maximum Heart-Rate for a Runner: The heart's pulse-rate for a
well-trained runner will increase at the beginning of a run, and
then decrease as the runner experiences a "second wind." There
after, the pulse-rate will gradually increase as the runner switches
from metabolizing glycogen to converting fat into an energy source.
This toy model mimics
this phenomena. It asks when the maximum heart rate will occur. The
answer is obtained with the standard tool: set the derivative equal
to zero and solve. It may be that the "solving" is the most
interesting part from the perspective of computing in this
worksheet.
-
Important geometric relationships exist between the graphs of
function f, the derivative of f and the integral of
f. This worksheet compares their
graphs and asks the user to identify which is which in an overlay of
the three graphs.
-
Area by Chance: The Riemann integral is usually defined as
the limit of a collection of approximating sums. There after, the
fundamental theorem of integral calculus provides methods for
evaluating integrals without computing limits of sums. As an
alternative idea, this worksheet introduces a
random number generator and what is usually called "Monte-Carlo
Techniques" to evaluate integrals. "Area by Chance" is a good
worksheet to examine early in the introduction of the integral.
-
Techniques of Integration: Substitution and Integration by
Parts: It used to be that a calculus class would study the
techniques of integra tion so well that the student could work out
how to integrate functions such as x arcsin(x). The computer can be
used to help with the calculus when methods suc h as substitution or
integration-by-parts are correct choices for integration techniques.
-
A Distribution of Weights : Most of us have experiences with
balancing a series of weights on a line segment . The balance point
is located at a point which may be computed as a combination of sums
and products of weights and distances from the balance point. For
the p urposes of the sciences, we often consider a solid as being
concentrated at a si ngle point. The location of the center of mass
of a continuously distributed wei ght is computed in this worksheet.
-
Rotations : When drawing a figure of revolution, there are
several ideas that ar ise: What will the figure look like? What is
the area of the resulting surface? What is the volume of the
enclosed solid? All three questions are addressed in this worksheet.
-
The Theorem of Pappus : Suppose that the plane region R is
revolved about the line L in the xy-plane. S uppose also that the
line does not intersect the region. The volume of the solid
generated is equal to the product of the area of R and the length of
the circum ference of the circle traced by the centroid of R. This
result of Pappus is illustrated
in this worksheet.
-
The Year of the Fastest Growth for the US Population: The U.
S. Constitution requires a census every ten years. We provide a
"Logistic Fit" for that data and graph the fit superimposed with the
data. This worksheet
then asks the following question: In what year does this logistic
fit suggest the fastest growth in the U. S. census data?
-
Growth, Decay, and Exponential Functions: The real reason we
learn about the exponential function in this course is that it has a
lot of important applications. In this worksheet we
discuss some of their applications to archaeology (carbon dating),
atmospheric radiation, and predictions of populations.
