## Lecturer Dmitri Zaitsev

Requirements/prerequisites: 1E1, 1E2
Number of lectures per week: 3 + 1 tutorial (tutorials starting week 2)
Duration: 11 weeks

The Annual Exam will have 6 questions. Credit will be given for the best 5 questions. Tutorial sheets/assignments counting 10% and Final Exam 90%. Examination material is within the scope of the problem sheets.

### NEW: Collaboration platform and Chat room

Rough hand-written Lecture Notes (not essential for understanding the material) can be found here, here, here and here for applications to ODE

Problem Sheets in PDF: Sheet 1 Sheet 2 Sheet 3 Sheet 4 Sheet 5 Sheet 6 Sheet 7 Sheet 8 Sheet 9

Most solutions to the exercises are very similar to those older ones that can be found here, here and here and here. Solutions to the last two exercises from 2015 are here.

Every problem in the calculus of variations has a solution, provided the word solution is suitably understood. -- David Hilbert

Objectives. The objectives of this course are to give the participants a basic grounding in the mathematics that underlies applications of the mathematics to engineering and to promote an ability among the participants to apply this knowledge to new situations.

### Course outline:

Linear Algebra: Chapters 3-6 (11th and 10th edition) or 3-7 (9th edition) in Anton-Rorres' book "Elementary Linear Algebra (with applications)". Euclidean n-Space and n-Vectors, Operations with them. Linear Transformations and their Matrices. Subspaces. Linear Combinations of Vectors. Subspaces spanned by a Set of Vectors. Linear Independence of a Set of Vectors. Basis and Dimension. Standard Basis in n-space. Coordinates of Vectors relative to a Basis. General and Particular Solutions for a Linear System. Row, Column and Nullspace of a Matrix. Finding Bases for them using Elementary Row Operations. Rank and Nullity of a Matrix. Inner Products, Lengths, Distances and Angles relative to them. Orthogonal and Orthonormal Bases relative to an Inner Product. Orthogonal projections to Subspaces. Gram-Schmidt Process (see Example 7 in Chapter 6.3). Eigenvalues and Eigenvectors of Square Matrices.
