Hello students myself Dr. Gajendra Purohit and I have done my Phd
in algebra and I have cleared the CSIR-NET exam.
I upload my videos for engineering mathematics and bsc students.
You all  face a lot pf problems as many students ask sir where
so please if you face any problem then here
a playlist is made for you so in that playlist
I have made separate
playlist so you can go and watch my videos there and if you face any problem
then in my comment box
you can go and comment. Students
there might be some small
mistake of plus or minus so
please do comment there so that I can rectify that.
In my pin comment also I am going to add that so that

they also get the benefits of this.
 
 
 
 
 
 
 
 
Hello students myself Dr. Gajendra Purohit an today I am going to start
logarithmic test for the infinite
series.
For any infinite series when we check the test for convergence and divergence so we
will discuss lot of tests
and today we will discuss logarithmic test.
Before this I have told you raabe's test. All these tests
are used when
d'alembert's ratio fails
then we use this test. Now you will say that sir
before this you have told raabe's test
then what is the need of this? When we find the limit in the raabe's test and
we find problem in finding the limit
then in that case we use the logarithmic test as
under some conditions
this test is easy as compared to raabe's test. Students
all my old videos on infinite series that I have uploaded
you can watch them here on the I icon. Students
I have more videos like
on engineering mathematics and bsc students
so all those videos are also uploaded here on the I icon
so you can go and watch them. Students you can go to my channel and watch in the playlist also.
I have uploaded a lot of videos there.
Students till now around 120 videos
I have uploaded for you all and in future also I will keep doing this and whatever is your requirement
or the course requirements like I have to upload this or that
so I will upload them soon. I have full faith
that your exams will go amazing and I
will help you completely. Students
if you have not subscribed to my channel
then do subscribe to my channel and press the notification bell
so that for all my upcoming videos you keep getting the notifications. Students
see what is logarithmic test and how do we check if the series is convergent
or not. So students what happens
is that first we apply the ratio test and
if ratio test fails then we check the limit for this.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
So students on logarithmic test maximum questions are of this type only so if you have any doubt
then you can comment in the comment box.
Students be with me. I will bring more amazing videos for you and all my videos
you can easily see in the playlist.
You all have more demands also as students comment that sir for this
upload the video or for that upload the video. So I will try that before your exams
I satisfy all your demands. Students if
you face any problem then do comment and do share with your friends.
Be with me. I will upload more amazing videos and content for you all. Thank you so much for watching videos. Thank you!
