This video helps you to answer objective questions on Relations and Functions. Topics covered are equivalence relations, functions, one one and onto functions. In my three decades of experience as a math educator, I have found students losing marks in 1 mark questions because that is where you need to know the topic inside out.This video teaches you intricate details about the number of functions from a finite set to another finite set, the number of one-one , onto, and bijective functions. This is Part 1 on this topic. More videos can be purchased at a price or you can contact me for online classes. A very useful video for Maths students of class 12 especially the students following the ISC and CBSE curriculum.
