**Course Objectives and Goals:**

MTH 243 is a third calculus course, with the focus on functions
of two, three, and more variables and the extensions of the ideas
of elementary calculus to higher dimensions. It covers coordinates for space vector geometry, partial derivatives, directional derivatives, extrema, Lagrange multipliers, and multiple integrals.

**Prerequisite:** MTH142

__Homework/Quizzes:__

Homework will be assigned after each section. Each day we will spend time going over examples, quizzes, and homework problems. You are responsible for all problems assigned, see Course Calendar for a list of problems associated with each chapter. Quizzes will be given almost every class in the weeks without exams. Quiz problems are from homework problems and examples given in class with number changes. There are no makeup quizzes. I'll drop one quiz grade.

__Attendance:__

Because of the high level of knowledge that will be imparted and assessed during class time, attendance is highly recommended.

__Calculators:__

A Texas Instruments graphing calculator is required. Technology will play an important role in this course and we will make extensive use of graphing calculators; sure to bring your graphing calculator to each class.

__Mathematica Projects:__

In this course we will use the Mathematica software, which is available in computer labs at URI. The Mathematica projects are created to help you learn new concepts. Mathematica is very useful in visualizing graphs and surfaces in three dimensions.

**Help With Your studies and homework:**

Tutors are available at both the providence and kingston campuses. Check with them for specific hours. Also, you can make individual appointments with me. For this, contact me by phone, e-mail, or ask me during class.

I may help you with questions during office hours, or at other times by appointment. Also, I will try to answer questions sent by electronic mail as promptly as possible. Students who require accommodations and who have documentation from Disability Services (874-2098) should make arrangements with me as soon as possible.
