ING1021 Series and functions of several variables

Contents and structure

The course contains the following subjects:

 

Functions of several variables

• graphs and level sets (level graphs)
• limits and continuity in several variables
• partial derivation, linearization and extreme values
• Sequences, series, and integral transforms:
• sequences, difference equations, series, and convergences
• power series representation and radius of convergence
• Taylor series
• Fourier series
• Laplace transform

 

In addition to understanding concepts and methods of calculation, emphasis is placed on logical reasoning, mathematical notation and the written presentation of solutions. Numerical methods are particularly useful for investigating sequences and series, and their convergence.

 

The items above are further illustrated with appropriate examples.
