This course introduces students to the mathematical techniques necessary for the study of economics at the undergraduate level. In particular, the course will cover univariate and multivariate calculus, optimization techniques and linear algebra. By the end of the course students should be adept at calculating derivatives, slopes of different graphs, concavity and convexity, single variable and multivariable optimization, Lagrange method. This course may be waived for students who have done both multivariate calculus and linear algebra in the mathematics department during their first year in Ashoka University.
