Even iit math lecturer are teaching by seeing in reference in hands, then why we should be fear of math.we writing exams without seeing,we are also great 😃
sir you vowed me in initial 15.34 sec. you cleared up my biggest mess of my school and engineering maths. i hope i would master the art of calculus by this and multivariate maths. sir is there a way to appear for this course certification?
I think Sir Fermat numbers are only odd numbers . Two odd numbers may be co prime but it doesn't mean that they are primes. Then how can you prove there are infinite prime by Fermat numbers. I may be wrong, its only my question. Please give me solution.
enjoyed your video. No offence, but I am always amused to see the high self worth in the style of Indian teachers where as the non-indian teachers/schools/universities I went to seem to be very naive, style-less, focused and brilliant nurds.
when i was thinking about irrational numbers i know the definition of that . but can anyone tell me about 22/7 where 7 isn't equal to zero and 7 , 22 both belongs to set of integers(by the definition of rational numbers). but on the other hand value of 22/7 is quite similar to an irrational number and if it happens it's violating the definition of irrational number. so sir if you kindly give me a clear idea about that it would really be helpful for me.
sandip kumar basak if you are referring to pi, then you must know that 22/7 is not equal to pi but an approximation of the value of pi. (22/7 is equal to 3.14285714and it repeats while pi = 3.14159265 and goes on without a pattern. Hence pi is irrational. Yup they fooled us in school. It’s part of a bigger conspiracy.
Actually pi is defined as the ratio of circumference of a circle to its diameter and it is constant for a given circle... 22/7 is almost close value to the pi upto 3digits so it is being used in calculations
Sir, in the last point in your saying for rational numbers you spoke that 'q' possess 2 and 5 as its prime factors. But in case 1/21 the denominator is 21 which doesn't have 2 or 5 as prime factors but though it's rational. Please make me clear one more time.
IF Q DONT HV 2 OR 5 IN ITS PRIME FACTORISATION THEN IT WILL HAVE A REPEATING AND NON TERMINATING DECIMAL EXPRESSION. ALTHOUGH IT WILL BE A RATIONAL NUMBER. IRRATIONAL NUMBER- WHOSE DECIMAL EXPRESSION IS NON TERMINATING AND NON REPEATING.
It's hard to believe that a nonzero terminating number can have two representations but it can be proved (rigorously and intuitively) that 2.3= 2.299...
Thank you Sir... I am also intending to watch your Optimization series. Greeting from Iraq
you are wonderful professor of mathematics. you know history of math which are spices for teaching and makes the subject interesting. Excellent.
Even iit math lecturer are teaching by seeing in reference in hands, then why we should be fear of math.we writing exams without seeing,we are also great 😃
The point of exam is not to test your conceptual understanding, it is to test your memory.
@@hel_0568 it depends on the question in my opinion

Go to nptel website or download the swayam app to apply for the course officially .
it is better than other nptel courses
at 31:41 he says proof is in notes. Where to find these notes ??
In the first proof, why we are taking format number?
Thank you very much Sir for such a great work. And Sir from where I can get the notes that you describes in the video.
File not found.
@Anubhav Mahapatra not found

Sir which book should we follow in correspondence with these lectures??

@Anubhav Mahapatra thanks sir
Are you active in you tube, I can clear your doubt, what Joydeep sir is trying to convey
Is it enough for know the basics from this vedio only without watching previous one
enjoyed your video.

boring you mean?
Very nice sir your teaching and your speaking is very style and attractive also sir
Thank you Sir
watch at 1.25x
thank you soo much sir

And thanks sir, but plz can you inform us where to get the notes
our no.system has 10 as base if we have took 8 or any other base these division rules would have changed
Sir please provide notes
Where will I find the notes, sir keeps telling in the video? Can someone provide the link?
Nptel website par search karo
Konsi class ka h ye , mai asi ghumta hua aa gya
Hey are u from IIT kanpur can I pls tell if this is in the course of Cse branch first year?
Please sir solve lagrange form of reminder
Thanx
so great but sir needs to move here and there.
Why 0.99999999999999999..........= 1 ?

leopond koneceker was not mathematician and his quote is dumb . humans created number andphilosphy behind counting
Please google him and his quotes
en.wikipedia.org/wiki/Leopold_Kronecker yeah what?
There is no passion in your work...
Pruthvi Kavaiya ?
I feel sorry for you.
Thank u sir
