Course Syllabus

Abstract

This course is designed to introduce students to the basic ideas and methods of mathematical analysis and their application in business management. This course serves as a basis for the entire block of quantitative disciplines studied at HSE, and it also provides some analytical tools required by advanced courses in information technologies. The course provides students with experience in the methods and applications of calculus to theoretical and practical problems. The course is taught in English.

  • understand the meaning of the derivative in terms of a rate of change and marginal analysis, and use derivatives to solve various problems.
  • understand the meaning of the definite integral as the net accumulation of change, and use integrals to solve various problems.
  • communicate mathematics in well-written sentences and to explain the solutions to problems.
  • model a written description of a simple situation with a function, differential equation, or an integral.
  • use mathematical analysis to solve problems, interpret results, and verify conclusions.
  • understand and explain the meaning of solutions, including sign, size, relative accuracy, and units of measurement.
