Abstract
In the process of studying the discipline, students will become familiar with theoretical foundations and basic methods of solving tasks on the following topics • Systems of linear equations. Row operations and Gaussian elimination. Vectors and Matrices. Linear spaces. Homogeneous systems and null space. • Matrix inversion and determinants. • Complex numbers and their properties. • Eigenvalues and eigenvectors. Diagonalization of matrices. • Inner product and orthogonality. Lines in R2, planes and lines in R3, lines and hyper-planes in Rn . • Orthogonal diagonalisation. Quadratic forms and conic sections

- Final examThe exam is ONLINE in written form. It is taken on Ms Teams platform. Students are required to join a session 15 minutes before the beginning. The computers must meet the following technical requirements: https://docs.microsoft.com/ru-ru/microsoftteams/hardware-requirements-for-the-teams-app A student is supposed to follow the requirements below: check your computer for compliance with technical requirements no later than 5 days before the exam; sign in with your corporate account (@edu.hse.ru); check your microphone, speakers or headphones, webcam, Internet connection (we recommend connecting your computer to the network with a cable, if possible); prepare the necessary writing equipment, such as pens, pencils, pieces of paper, and others. Disable applications on the computer's task other than the MS Teams application or the browser that will be used to log in to the MS Teams platform. Students are not allowed to: turn off the video camera; use notes, textbooks, and other educational materials; leave the place where the exam task is taken (go beyond the camera's viewing angle); look away from your computer screen or desktop; use smart gadgets (smartphone, tablet, etc.) involve outsiders for help during the exam, talk to outsiders during the examination tasks. Students are allowed to: write on a piece of paper, use a pen for making notes and calculations; use a calculator (not on mobile); turn on the microphone to answer the teacher’s questions; ask a teacher for additional information related to understanding the exam task. A short-term communication failure during the exam is considered to be the loss of a student's network connection with the MS Teams platform for no longer than 1 minute. A student cannot continue to participate in the exam, if there is a long-term communication failure appeared. The retake procedure is similar to the exam procedure. In case of long-term communication failure in the MS Teams platform during the examination task, the student must notify the teacher, record the fact of loss of connection with the platform (screenshot, a response from the Internet provider). Then contact the manager of a program with an explanatory note about the incident to decide on retaking the exam.
