I came across this channel today. I had been searching for isi solutions for so long and I finally found this video. It was very helpful. Thank you.

[EDUMATHZONE]

Really you deserved more subscribers as you real depth in the field of mathematics.please do more videos on jee sir

[EDUMATHZONE]

Really your explanation is awesome sir better such commercial you tube channels like Vedantu and in academy keep it up . It is from my bottom of heart sir 🙏🙏🙏🙏👏👏👏👍👍👍

[dibakarbiswas]

totally innovative way of your thinking and solving such type of problems

Sir in Q4, you used newton leibniz theorem but did partial differentiation for the limits. Is it possible to do that? So far I have only learnt it with complete differentiation of limits.

[madhumitha]

Sir, in question 1, you've only showed that it's not possible to express the powers of 2 in that form, but aren't we actually supposed to show that every positive integer other than the powers of 2 can be expressed in that form?

[mahimabalusa]

Thank u for the session sir it was very difficult to me preparing for isi now I got idea about the questions☺️ tq soo much sir

[apurbaadhikari]

Sir in Q2, you should have taken two cases of x, because in question it's written that, x is positive, so the cases must be 0<x<1 and x>(or equal) 1. ? Please respond.

[SV-yonq]

I think your solutions to q1 is incomplete. Problem asked to prove that the set of all numbers not satisfying that property is exactly the same as the set of 2^l, you just proved that the set of 2^l dont satisfy that property

15:38 why did you differentiate y wrt x . Why did you treat y as a constant

[jishuadhikary]

sir many many thanks to you for your this wonderful initiative . it really helps students a lot more than various paid coures.... sir please suggest some book for integral calulus .please sir ...

[vishalmaurya]

Thank u sir...you are very helpful...simply you work hard only for students...thank u sir

[ECESayakchatterjee]

Sir also suggest some books for subjective, Tomato book subjectives are enough for ISI B math ??

[asmita-jedy]

Thank you so much for the video! In the 4th question, while differentiating f(x), why do we not have to use product formula? I get that while using the leibnitz formula y would be constant but why is it constant outside the integral? Please answer if you get what I’m trying to ask🙏🏽

[IshanBanerjee]

Sir in question 6, I got the expression from An=2sin(π/2^n) using sin2θ=2sinθ√(1-sin²θ), will it be fine sir ?

[cyanide]

The solution to problem one is correct except one thing that is u have to prove that every other integer is possible, u showed that 2^m types of numbers are not possible but what if say 20 is also not possible but 20 is not of the form 2^m therefore u haven't proven that all integers that cannot be written as the sum of consecutive positive integers are of the form 2^m

[prajyotkore]

Sir, keep it up! U will be Monopoly soon!

[blueyahoo]

Sir in the 4th question why we are not differentiating the 'y' ? Are we considering it as a constant?
One more question what is the Newton's lemme's formula?

[THUNDER-kwwq]

Sir in ques no.5, we have nowhere used the concept of convex quadrilateral
