# One markers -Relations and Functions-Maths-Class 12

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.
