MTH 212 CALCULUS III
Students will be expected to
demonstrate an understanding of Calculus beyond the manipulation of symbols,
apply Calculus to practical problems and use current technology throughout
the course. They will demonstrate their understanding of Calculus using
three approaches -- geometric, numerical, and algebraic. A comprehensive
final exam testing the degree of mastery of the following objectives is
required:
- Functions of Many Variables
- Represent and evaluate functions of two variables graphically
(contour maps), numerically (tables), and by formulas.
- Interpret functions of more than one variable by holding all but
one variable fixed.
- Plot points and draw graphs of functions of two variables as
surfaces in three dimensions using traces in planes parallel to
the coordinate planes (i.e. cross sections obtained by holding all
but one variable fixed).
- Graph cross sections for a function given by its contour diagram.
- Represent and recognize linear functions as tables of values,
parallel, equally spaced contour lines, flat surfaces, and first
degree equations.
- Represent functions of three variables as level surfaces.
- Vectors
- Find the magnitude, direction and component form of displacement
vectors.
- Perform the following vector operations: addition and subtraction
scalar multiplication dot product, geometric and component forms
cross product, geometric and component forms
- Use vector models for applications of velocity, force, work,
finding angles between vectors, and projections.
- Recognize, construct, and interpret equations of planes from
tables, contour lines, 3 points, and a point and a normal vector.
- Partial Derivatives
- Find partial derivatives in direction of x, y (z, etc.) in any
direction using numeric, graphic, and algebraic computations.
- Interpret units and signs of partial derivatives.
- Find tangent plane approximations and discuss local linearity
for functions of two variables.
- Find and interpret differentials for functions of two variables.
- Compute gradients geometrically and algebraically.
- Find maximum, minimum and zero rates of change and their directions
using the gradient.
- Give the gradient in component form.
- Use the gradient to find directional derivatives.
- Use chain rules to determine derivatives and partial derivatives
for functions of several variables and to solve applied problems
involving related rates of change.
- Find Second Order Partial Derivatives given an algebraic representation
of a function.
- Find the signs of first and second order partial derivatives
given a contour diagram for the function.
- Determine whether or not a function satisfies a partial differential
equation.
- Find a Taylor Polynomial of degree two, i.e. a quadratic approximation,
for a function of two variables.
- Optimization
- Find global and local extrema for a function given algebraically
or via its contour diagram. Use the second derivative test to distinguish
among local maxima, local minima, and saddle points.
- Solve word problems involving optimization of functions of two
or more variables, including maximizing profit, and least square
approximations.
- Solve problems in constrained optimization using the method of
Lagrange multipliers, algebraically and using a contour diagram.
- Multiple Integration
- Use a Riemann Sum to approximate a double integral, where the
Riemann Sum arises from an application, as total population given
a density function over a two dimensional area (e.g.. fox density
map of England).
- Interpret the two-variable integral as a volume under the graph
of a function of two variables, a total amount of a function of
two variables (when the integrand is density per area), and the
volume over the region of integration at a constant height equal
to the average value of the integrand on the region.
- Sketch regions of integration and reverse the order of integration
for double and triple integrals.
- Set up and evaluate double and triple iterated integrals over
2- and 3- dimensional regions.
- Set up and evaluate definite integrals in two dimensions using
polar coordinates. Change from polar to rectangular coordinates
and vice versa.
- Parametric Curves
- Describe the motion in the plane or in space of an object using
parametric representation.
- Find and use velocity and acceleration vectors for motion described
parametrically.
- Represent curves parametrically, implicitly and explicitly. Be
able to convert from one form of representation to another.
- Use the velocity vector to find the length of a curve.
- Vector Fields
- Give vector fields via a formula or sketch. Convert between these
representations.
- Recognize types of vector fields, including velocity fields,
force fields, and gradient fields.
- Draw flow lines in a vector field.
- Show that a particular flow satisfies the differential equations
for an associated vector field.
- Line Integrals
- Define the line integral as the sum of dot products of vector
field and path elements. Determine the sign of a line integral given
a sketch of the field and the path.
- Apply the concept of line integral to work and circulation.
- Compute line integrals given the component functions of the vector
field by parameterizing the path (oriented curve).
- Apply the fundamental theorem of calculus for line integrals
using the gradient of a scalar function.
- Know the definition and properties of conservative vector fields
and their relationship to gradient fields.
- Equate path independence with circulation free.
- Discuss the fact that nonconservative fields are neither path
independent nor circulation free.
- Apply Green's Theorem to evaluate a line integral on a closed
path.
