as many students complain that sir we are not getting this topic that topic
so here the complete playlist is arranged topic wise
so you can go and watch my videos
Hello students myself Dr. Gajendra Purohit and today I will
teach you the topic of length of arc
which I was teaching before now there are some numerical questions which are important
from exam point of view
that I will discuss which includes asteroid and
there is one more concept where we will trace the loop and find the length of the loop
as they are usually asked in the exam
and after this I will talk about cardioid and how we calculate the length of the cardioid
with the help of polar formula that I will explain you separately
and students before this
engineering mathematics, bsc and other competitive
exams like IIT-JEM, CSIR-NET , GATE
or whatever exams that you are giving or other government competitive exams
so the videos related to that are uploaded here
so you can go to the I icon and watch my videos
ans students let's see how we solve these types of questions
and if you have not subscribed to my channel then please subscribe and press the notification bell
so that for all the upcoming videos you can get the notification

so students if you don't know the method to trace the curve so here on the I icon
so here do watch the video on curve tracing because if
you will see that so here the curve tracing
concept you will understand much easily. So see here

so if you don't understand try to watch the videos once again and try to understand as this is a easy question
and you can do it easily. Students today's topic
end here only and in my next video in that I will tell you for polar
curves how we calculate the length of arc in which
the most important question is on cardioid which in exams
is usually asked every one or two years
so now I will bring that video for you
so students thank you so much,be with me
as I am uploading a good content for you and the screen at the last
which is appearing you can find the links for my old videos
