The system of mathematical education at the A. N. Tupolev Kazan National Research Technical University (KNITU-KAI) is described. It is suggested that the mathematics course at a technical university should be diversified. This should be ensured for different areas by the difference in the selection of material, the placement of emphasis on the relevance of the studied sections of mathematics in the specialized disciplines. It is proposed that the development of interest in mathematics for future engineers can be provided by solving professionally oriented problems, showing the use of mathematical sections using specific examples from the disciplines of the professional cycle, and thus drawing the attention of junior students to the need to have solid mathematical knowledge. The author points out the significant role of online training courses at KNITU-KAI. It is assumed that e-courses allow a deeper study of the material presented by the teacher in lectures and practical classes, and they also provide an opportunity to qualitatively prepare for control activities, for intermediate certification.
