**Description:**
MTH 243 is a third calculus course, with the focus on functions of 2,3, and more variables
and the extensions of the ideas of elementary calculus to higher dimensions.

**Objectives:** At the conclusion of this semester you will be able to:

- read and interpret 3d plots and 2d/3d contour diagrams, read and interpret tables of functions of several variables, and plot by hand the graph of simple functions of 2 variables, and simple contour plots of 2 or 3 variables,
- do calculations with vectors that involve the concepts of addition, scalar multiplication, dot product, cross product, magnitude, projection, and use these concepts in geometry and physics applications,
- calculate partial and directional derivatives, gradients and differentials of function of several variables, use local linearization to approximate functions,
- calculate critical points, use the second derivative test to determine local extrema and saddle points (for functions of two variables only), use these concepts to solve unconstrained optimization problems, and use Lagrange multipliers to solve constrained optimization problems,
- calculate double and triple integrals algebraically, change variables in integrals from rectangular coordinates to polar, cylindrical, spherical coordinates and vice versa,
- use the concept of parametrization,
- represent and interpret plots of vector fields (including flow lines),
- use vector valued functions to do calculations of line integrals, and apply Green's theorem.

**Textbook:**

Please login into sakai at URI.

**WileyPlus:**
We will be using WileyPlus online homework system this semester.
To sign up for the WileyPlus system, you will need a WileyPlus registration code.
If you buy a copy of our textbook at the URI Bookstore, a registration code
for WileyPlus will be included with the book at no additional cost.
If you buy a copy somewhere else and it does not include WileyPlus code, you will need to purchase a WileyPlus code separately.

**Calculator:** A graphing calculator is strongly suggested.

**Prerequisites:**
MTH 142 or equivalent.

**Accommodations:** Any student with a documented disability
is welcome to contact me as early in the semester as possible so that
we may arrange reasonable accommodations. As part of this process,
