MAT 241  Calculus III [SUN# MAT 2241] 4 Credits, 4 Contact Hours 4 lecture periods 0 lab periods
Continuation of MAT 231 . Includes vectors in two and three dimensions, vectorvalued functions, differentiation and integration of multivariable functions, and calculus of vector fields.
Prerequisite(s): Within the last three years: MAT 231 with a grade of C or better. GenEd: Meets AGEC  MATH; Meets CTE  M&S.
Course Learning Outcomes 1. Use vector operations to calculate equations of planes and vector equations of lines.
2. Use partial derivatives to analyze rates of change of multivariable functions in a variety of contexts.
3. Evaluate double and triple integrals of multivariable functions in a variety of coordinate systems.
4. Evaluate line and surface integrals in vector fields using a variety of theorems and techniques. Performance Objectives: 1. Use a Cartesian coordinate system in 3dimensional space; perform vector operations including the dot and cross products; and find the orthogonal projection onto a vector.
2. Determine equations of lines and planes in space, and identify and classify quadric surfaces.
3. Evaluate limits, derivatives and integrals of vectorvalued functions; analyze motion along a curve; and calculate the unit tangent vector, the unit normal vector, and the curvature.
4. Evaluate limits, determine continuity, and calculate partial derivatives of multivariable functions; apply the chain rule and use implicit differentiation; calculate directional derivatives and gradient vectors; find equations of tangent planes; determine extrema and saddle points; and use Lagrange multipliers to find constrained maximum and minimum.
5. Evaluate double integrals in rectangular and polar coordinates; convert between rectangular, cylindrical, and spherical coordinates; evaluate triple integrals in rectangular, cylindrical, and spherical coordinates; and use double and triple integrals to calculate volumes.
6. Determine if a vector field is conservative and find a potential function; evaluate line integrals of realvalued functions and vector fields; evaluate surface integrals of realvalued functions and vector fields; and use Green’s Theorem, Stokes’ Theorem, and the Divergence Theorem to evaluate line integrals and surface integrals.
