MATH 2111: Calculus III-Multivariable Calculus

This course takes calculus from the two dimensional world of single variable functions into the three dimensional world, and beyond, of multivariable functions. Students explore the following topics: vector geometry and the analytic geometry of lines, planes and surfaces; calculus of curves in two or three dimensions, including arc length and curvature; calculus of scalar-valued functions of several variables, including the gradient, directional derivatives and the Chain Rule; Lagrange multipliers and optimization problems; double integrals in rectangular and polar coordinates; triple integrals in rectangular, cylindrical and spherical coordinates; calculus of vector fields including line integrals, curl and divergence, fundamental theorem for line integrals and Green’s theorem.

Learning outcomes

  • Handle vectors fluently in solving problems involving the geometry of lines, curves, planes, and surfaces in space.
  • Visualize and draw graphs of surfaces in space.
  • Differentiate scaler functions of vectors.
  • Integrate vectors.
  • Calculate extreme values using Lagrange multipliers.
  • Solve double and triple integrals.
  • Translate real-life situations into the symbolism of mathematics and find solutions for the resulting models.
