The videos on this post will make you understand the concept behind the functional relationship between one set to another. Mathematical functions basically can be defined in two manners and we will learn them both from the videos.

These three basic videos will define what a function means, what is the domain and range of a function and what are the most common types of function. In these basic videos we will learn about identity and constant functions and their graphs.

2 Price consumption curves videos

In these videos we discuss what is price consumption curve and how to derive demand curve from these. Price consumption curve is the locus of equilibrium points when price of one of the good changes.

One application of derivation of PCC and hence demand curve for perfect complements is also done for better understanding Continue reading →

5 Revealed preference concepts you must know

Here in these videos, we discuss the concept of revealed preference. We start by explaining what is the meaning of revealed preference and then define and explain what are WARP and SARP. We conclude this presentation by two simple numerical examples about how to check whether WARP and SARP are satisfied.

Hopefully, this presentation on revealed preference will be useful to you. Continue reading →
