Introduction to Mathematical Economics

Resources for聽Introduction to Mathematical Economics聽- for more information about the course, please see course outlines.

Note: The name of this course changed in 2020. It used to be called "Introduction to Mathematical Economics (Basic)", so most of the old seminars mention this course name. However, the course content is the same.

  • Maths notation

    The MLC gave a seminar in 2013 about maths notation, which ought to be helpful for revising or learning maths notation. Video and handouts are at the following page.

  • Calculations and algebra

    In this course you learn about calculating with numbers, fractions and algebra. The MLC gave seminars on these topics in 2015, and all the videos are collected on the following webpage.

  • Functions

    In this course, it is important to know what shape various functions are, simply from looking at their formulas. The following mini-textbooks聽 are about various types of functions and contain explanations and practice exercises.

    This revision seminar was given to students in a different course called Intro to Financial maths, and it began with a section on quadratic functions, including the various forms to write them and how to find solutions.

    The following lecture was given for students in the MathTrack聽bridging course, and it gives a lot of information about how polynomial functions work.

  • Differentiation

    In Semester 1 2014, David gave a revision seminar聽on differentiation. David discussed functions, differentiation, partial differentiation and lagrange multipliers.聽

    In Semester 1 2021, David gave a revision seminar about differentiation and using it to find maximums of both one-variable functions and several-variable functions.

    In Semester 1 2022, David gave a revision seminar about differentiation, partial differentiation, and constrained and unconstrained optimisation of two-variable functions.

    In Semester 1 2023, David gave a revision seminar discussing聽various things to do with multivariable calculus, including marginal rate of substitution, second order partial derivatives and constrained optimisation.

    The following resources were created for the MLC bridging course MathsTrack, and might be helpful for understanding derivatives and maximisation of one-variable functions. (Some of the presentation might be quite different than in your course though.)

  • Revision seminars in order of time

    Over the years, the MLC has given several revision seminars to students in this course where requests were taken from the students for what to talk about. They are listed here with the newest seminars at the top.
