Multiple integrals, contour integrals and Green's formula. Applications.

Basic course in differential and integral calculus in several variables. After the course the students should know and be able to use the basic concepts in the calculus of functions of several variables: partial derivative, differentiability, differentials, gradient, directional derivative, total derivative, Jacobian, multiple integrals, contour integrals.
More specifically after finishing the course the students should be able to

• apply the chain rule and decide wether a function satisfies a certain partial differential equation
• compute tangent planes and directional derivatives using the gradient
• compute limits of certain functions of several varaibles and decide whether it is differentiable
• form differentials and Taylor expansions of functions of several varaibles
• transform partial derivatives by changing variables
• use total derivatives and Jacobians to solve problems in connections with local existence for inverse functions and implicit functions
• compute and analyze the type of stationary points
• solve optimization problems for different types of regions with or without constraints
• use the method of least squares
• compute certain multiple integrals
• use multiple integrals to compute volumes and area, and compute the length of curves using integrals
• compute contour integrals using parametrizations and Green's formula

SF1644 Calculus in one variable and SF1645 Linear Algebra.

If the course is discontinued, students may request to be examined during the following two academic years.

• TEN1 - Examination, 6.0 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

One written exam

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
