Hi Everyone !!!
My name is Ravina , welcome to “Ravina Tutorial”. Here you will find video lectures related to Bsc/Msc (Higher Mathematics).These video lectures are concept oriented & explained in very simple language. I feel after watching these videos you will clear most of the doubts(sometimes I also creat doubt :).
In this video we will study all about Euler’s Function:
it’s definition
it is multiplicative function
euler’s theorem
Example based on it
