What Basic Math To Know Before Calculus (Functions)

You'll be able to translate the concept of function and its properties to different points of view: Relations, procedures, diagram, tables and graphs.
You'll be able to understand what are 1-1, onto and bijective functions logically and intuitively.
See change of variables and function transformation under the light of functions composition and image of sets.
Get a solid foundation of function Inverses.
What is a square root? We'll see in detail using the notion of inverse.
Requirements
A basic knowledge of functions at the high-school level is mandatory.
Having college calculus under your belt will bring the greatest benefits.
Description
After 5 years of tutoring high-school and college students in all sort of classes in Mathematics and Physics I realized the many missing fundamental concepts these students lack and what they struggle with. As a result I created a lecture series to address all those issues. This is Part I of that lecture serie and is related with Functions.I cover the traditional topics in the subject of functions, here are some of the issues we'll address:What are functions? We'll give different points of view such as relations, procedures.Functions viewed as labelers will motivate the notions of 1-1, onto or bijective functions.What operations can be made with functions? Sum, multiplication, division, composition, restriction. We'll see these in detail. These are very simples but they contain many important concepts in mathematics, we will find them.Use composition of functions as a means to understand change of variables, moreover when combined with image of sets, allow us to better understand function transformations. This is one of the subjects that students have more difficulties, both high-school and college. It is now that you'll make sense of them.What is the inverse function? This is intimately connected with bijective functions. And what about those that are not bijective, what should we do? We'll discuss in detail examples of both.Together with this lecture videos you'll find a pdf file. The videos complement the sections of the pdf, which also has the exercises with solutions. On the title of each video you find the corresponding section of the pdf.
