This course will cover fundamental techniques such as (i) basic algebraic procedures, simple and simultaneous equations; (ii) functions, types, and graphical representation. (iii) simple economic applications and simple market models; introduction to calculus, including (i) concepts of Slope and continuity, (ii) meaning of derivatives and differentiation, (iii) techniques of differentiation and rules, (iv) applications to economic, phenomena, comparative statistics, elasticities, propensities, input-output models. It will also look at functions in one variable, including (i) maximum and minimum points, (ii) second order conditions, and (iii) applications. Functions of two or more variables such as (i) partial derivatives (ii) determination of maximum and minimum points, (iii) second order conditions (iv) constrained maximization, the Lagrangean Technique, First and Second Order Conditions, applications, profit maximization and consumer choice problems, input and output demand functions, cost functions and introduction to integral calculus, (ii) techniques and rules of integration (iii) applications. Investment, saving functions and growth models will also be treated.
