Super nostalgic problem! I appeared for IITJEE in 2011, and this was an integer type question on my paper. Ended up getting the problem right too! 😊

[@shubhsavivaah7085]

heyy what are u doing now?

[@bishnugautam4482]

Hello Aman sir!! I have found your lecture in pw official channel , couple of days ago!! The energy you bought in lecture are whole another level, seriously watching your lecture in 1.5x gives another level of josh while studying maths, Basically Keep going sir!! you are some of that teachers. You are my Guru aman sir,,, keep making Lots of support and love from Nepal, Thank you for everthing!!!

[@mirakalita5775]

Awesome question, I had fun

[@holashadow1846]

Very nice problem sir❤

[@jagithgunti]

It is a good question sir tq u

[@rudrashroff8282]

sir I did this question but in a different way, actually by using the angle property of regular polygons(sum of exterior angles always=360)

[@LGFZ136]

today was the feeling of bhannat

[@TechClimber]

Same answer as I did

[@Mindblo]

I took all nth roots of unity A1 be 1 and A2 A3 A4 be e^itheta,2theta and 3theta respectively where theta = 2pie/n and solve

[@anukalpdamor7923]

In first question how can be A1,A2 which are vertices can be multiplied
Btw i just started studyung trigo in my coaching

[@santoshanand8661]

Sir pls solve 1/cosx = 1/cos2x +1/cos3x

[@RsImperial]

good

[@vastavarya]

Sir problem no. 3 didn't come on telegram

[@panik8329]

Sir es ques ko using complex number easily solve kr skte hai

[@atulakumarsahoo7048]

The smart board server is of PW

[@jeetbangari2279]

Sir mera answer 8 bhi aa raha tha jab sin(2x)+sin(3x) so simplify kiya udhar ki phir niche Sin(2x) ka jo sum ban Raha tha usko expand karke kata piti karke n ka value 8 aa raha tha meri galati kidhar hui??

[@twligtbebe5717]

Sir I am unable to solve ur question

give time to math
try to develop your brain to understand complex things
i am in iit delhi 3rd year
and this star series is really gud

Sir i have taken this from vectors to trigonometry

[@SarveshSingh-kw8xb]

Koi Sir ka batch liya hain to please batao?

[@naharkakkar1638]

Sir I have a doubt as cos3x is 4cos³x -3cosx then we can not write cos(a+b+c)=4cosa.cosb.cosc-cosa-cosb-cosc as writing 3x to x+x+x and replace x by a,b,c respectively

[@annibhaigamings865]

x ko ya to a lo
Ya to b, Varna saath mein nahi le sakte, invalid ho jaayega

Sir I could solve it but it was lengthy

Sir give solution of
f(y)-f(x)=(x^x/y^y).f(y^y/x^x). Given f'(1)=1

[@vijaypalyadav3398]

_f(x)=xlnx+C_
Ye hai kya solution iss equation ka
Ya fir constant C bhi find karna hai
And actual i think is
_f(x)=xlnx_
Please tell it's correct answer
