# Calculus - Analytic Geometry III

Spring 2017

Hi, here is some information about my course Calculus III (CRN: 31410, MAC 2313-001, 4 credits). We meet Tuesdays and Thursdays 2 - 3:50 p.m. in PS 111.

The origins of calculus go back at least 2500 years to the ancient Greeks, who found areas using the "method of exhaustion". Limits arise not only when finding areas of a region, but also when computing the slope of a tangent line to a curve, the velocity of a car, or the sum of an infinite series. In each case, one quantity is computed as the limit of other, easily calculated quantities. Sir Isaac Newton invented his version of calculus in order to explain the motion of the planets around the sun. Today calculus is used in calculating the orbits of satellites and spacecraft, in predicting population sizes, in estimating how fast coffee prices rise, in forecasting weather, in measuring the cardiac output of the heart, in calculating life insurance premiums, and in a great variety of other areas.

This course Calculus III is about Calculus in three-dimensional space. We can describe the motion of objects in terms of vector valued functions:

f(t)= (x(t),y(t),z(t))

and use calculus methods to derive the velocity and accelleration (which now has a tangential and a normal component) of the moving object, and properties of its track, like the distance travelled and the curvature at a given point. Functions in several variables, for example:
f(x,y) or g(x,y,z)

describe the elevation of a surface or the densitiy of a three-dimensional substance. They can be analyzed using partial derivates, the gradient vector and multiple integrals. The gradient vector itself is an example of a vector valued function in several variables. Such functions are the topic of vector calculus, of which we will get a first glimpse in the final chapter of this course.

Prerequisite

Calculus II with a minimum grade of C.

Textbook and Topics

Briggs, Cochran, Gillett: Calculus, Early Transcendentals, 2nd Edition

We are going to cover the following chapters:

 Chapter 11 Vectors and vector valued functions(4 weeks) We review vectors and operations on vectors (dot product, cross product) to study points, lines and planes in three-space. We use derivatives and integrals to study the motion of objects in three-dimensional space. Chapter 12 Functions in several variables(3 weeks) Complicated quantities may depend on several input variables. Using partial derivatives we can solve maximum and minumum value problems. Excursion. We will explore how computer algebra (Sage) can be used to define functions, compute integrals, and to assist us in graphing. You can earn extra credit for using Maple or another computer algebra system to solve Calculus problems. Chapter 13 Multiple Integration(3 weeks) Suppose the height z of a solid S depends on the x- and the y-coordinate of the base point. Then the volume of S can be expressed as a double integral. We study multiple integrals and explore their applications. Chapter 14 Vector Calculus(4 weeks) Vector fields are vector valued functions in several variables, for example the direction of the flux in a liquid. Integrals can express, and integral theorems can relate, properties of such functions.

Objectives

• Use vectors, vector arithmetic, vector valued functions and functions in several variables to discuss quantities in three-dimensional space.
• Apply derivatives to study the motion in higher dimensional spaces, and also to describe the shape of surfaces.
• Use multiple integrals to express and evaluate quantities from mathematics, physics and engineering that depend on several variables.
• As part of extra credit projects, use computer algebra systems like Maple or Sage for visualization and computation.
• Communicate about calculus problems using computations, sketches and proper mathematical language.

Tutoring

There is free math tutoring available in the Math Learning Center in GS 211 (M-R 9-6, F 9-4, N 1-5). See MLC for making appointments. For more details, please e-mail mlc@sci.fau.edu or see the Assistant Director in GS 211E.

Homework:  I will assign homework problems every week. The problems will not be graded, but some may come up on a quiz:   Homework problems.

Quizzes:  We will have a quiz every Thursday of about 20-25 minutes each; the eleven best quizzes (of thirteen) count for 60 % of the grade. No calculators can be used during the quiz.

Extra Credit:  You can obtain extra credit counting towards your quiz grade for assignments done on a computer algebra system, for example Sage or Maple.

Final Exam:  The final exam is scheduled for Sunday, April 30, 4 - 6:30 p.m. It is comprehensive and counts for 40 % of your grade. Please bring a picture id (Owl card or drivers licence)!
