Intended learning outcomes

It is important that the student both UNDERSTANDS the mathematical theory and also knows how to APPLY it to concrete problems.

After completing this course with a passing grade the student should be able to

  • Use, explain and apply fundamental concepts and methods of calculus of several variables, especially
    o interpret graphs of functions and level curves/level surfaces and sketch such curves and surfaces in simple cases
    o calculate partial derivatives and use the chain rule for real valued functions and vector valued functions
    o find and classify critical points
    o use Taylor’s formula to approximate functions with polynomials to a desired degree of accuracy
    o use the Jacobian matrix for linear approximation
    o use the gradient to find directional derivatives and be able to explain its relation to level curves/level surfaces
    o solve certain optimization problems, including problems with constraints
    o explain how multiple integrals are defined and how they can be approximated by Riemann sums
    o evaluate certain multiple integrals by iterated integration and by change of variables, in particular by using polar, cylindrical and spherical coordinates
    o explain how integrals can be used to calculate lengths, area, volumes and other items e. g. mass and center of mass.
    o account for the definition of line integrals, surface integrals and flux integrals and evaluate simple instances using parameterization
    o account for and apply Green’s theorem and the divergence theorem
    o explain the concepts of a potential and a conservative vector field and use them in calculations
  • Propose models for applications that can be described by functions of several variables or vector-valued functions, discuss relevance and accuracy of such models and be aware of how mathematical software can be used in calculus of several variables.
  • Read and understand mathematical texts on calculus of several variables and its applications, and communicate mathematical reasoning within this field orally as well as in writing.
  • Explain how the Jacobian matrix can be used to decide whether a function is locally invertible.
  • Apply the implicit function theorem.
  • Account for and apply Stokes’ theorem.
  • Calculate limits of functions of several variables and decide whether a limit exists.
  • Account for the concepts of limit, continuity and differentiability of functions of several variables.
  • Solve problems in several steps that require more extensive computations.
  • Generalize and adapt methods to fit into partly new situations.
  • Solve problems that require methods and concepts from several parts of the course.
  • Deduce important formulae and theorems of calculus in several variables.
