Hello Students! Myself Dr. Gajendra Purohit
I have done my Ph.D. in Algebra
Also, I have cleared CSIR NET
I upload videos for Engineering Mathematics and B.Sc students
Students face problem in finding my videos
So if you are facing the same problem, please see the playlist
I have made different types of playlists for all videos
If you are facing any problem
you can comment in my comment box
If there are small mistakes in my videos, you can also comment that  in my comment box
so that I rectify that
I will put it in my pin comment
so that you will know the mistake in video beforehand only
Students if you are preparing for CSIR NET
Then download the Unacademy App on your playstore
search Gajendra Purohit there
and follow me there
so that you will get notifications of all my courses
And also rate and review my courses and share with your friends
So that they also benefit from it
 
Hello students! Myself Dr. Gajendra Purohit
Today I am going to start with Absolute Convergence
earlier I have uploaded videos on Infinite Series
and before this, I have taken the concept of Alternating Series
By Leibniz Test we use to find out
that the Alternating Series is convergent or divergent
I have uploaded more videos
you can click on i-tab for all my previous videos
if you are liking my videos, then please subscribe to my channel and press the notification bell
 
Let see what is the concept of Absolute Convergence
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
So students lets see these 2 questions to find out the convergence
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Let's see the last example
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Students ask how we will know that we have to find out Absolute convergence
so whenever there is an Alternating Series you have to find out Absolute convergence
 
 
 
 
My next video will be on the concept of Conditionally Convergence
 
 
students are demanding to make videos on Mechanics and Dynamics
Statistics and Probability
linear programming and operational research
 
 
 
 
 
 
 
So I will upload my videos on that soon
 
 
Thank you!
