Which Method you loved the Most??
Quadratic method
5th
Out of the box one🔥🔥
Quadratic method was most interesting!!
5th one was amazing
Method 7: Divide numerator and denominator by z . Then 4z+2/z is purely real. Solving we get |z|^2=1/2
COOL!!
Yes I did the same
@@vedants.vispute77 thaks bhaiya
Nishant Jindal ne jab solutions diye the usne same diya tha I feel like vahi se hi bata raha hai bhai tu
@@kamranjeetsingh8610 haan sahi h tu
thank you so much for this sir, even though I knew the concept of all the 6 methods, never thought of applying it this way which makes me wanna work more deeply!
jee advanced pyqs are nothing in front of some 2022 mains questions 🥲
Just for maths
Sahi bola selmon bhai 😭
I have literally started doing PYQs till 2021 only in maths
These 2022 questions make me feel dumb af ( already I'm not smart enough in mathematics)
@@srinivasvarkala8268 obviously Bhai , PC ki itni aukat nhi hai 😂😂 except that flux wala question
@@soumya_who same bruhh , 2021 walo tk confidence high thaa but 2022 wala attempt krke lg rha ki aaj tk kuchh nhi padhai krri
POV:you never solved single jee adv pyq
🤣
Shortcut method :
Z=a+ib ; (b not equal to zero) but ( a can be zero) therefore Z=ib , by puting it ,eqn simplifies
It's not a reliable method 🙂
@@IITian_Shivamm It's not at all reliable, if the solution was in z (polynomial of z), then there may not be a purely imaginary z that would satisfy the condition. But luckily the solution is in |z| allowing all type of complex numbers
Sir my method was too cheap i think cuz what i did was ( 1:41 )
Since its a real number i just thought if 2+4z^2 become 0 in numerator and denominator then we'll be left with 3z/-3z which is -1 which is purely real
So i just put 2+4z^2=0 so 4z^2=-2 So mod z^2=1/2
The methods were mind-blowing ❤️
Haats off to both Iqbal sir and Anup Sir for their Efforts ❤️
Quadratic and conjugate pair is the best method I found,,,and putting zero is also the awesome method....
I haven't properly studied complex numbers yet, I am unable to solve even mains level properly. But ironically enough, when I first saw the question, what came to mind was what you did as method five, that put a smile on my face but I know it's nothing to be happy about. Yet it's reassuring I at least have a good thought process now which I certainly didn't have before. I am a student at your ongoing crash course and I believe it's thanks to it that I was able to improvise at mathematics so much in a matter of months. Thanks a lot sir 🙏
amazing bro
No it's commendable! Good job!
@@Charlie0308 Thank you, means a lot when I have advance coming up
@@8BitGamerYT1 Thank you
@@Devhes how much in mains
Sir I would like to add one more methods
We will assume it to be rcosx+irsinx
With would make the calculation even simpler
Everything that's related to learning new methods comes from experience and this was an amazing video and the last method was really nice but we were able to do that because be knew it would be 1/2 and not due to hit and trial(by putting -1)
i don't know why but i am loving this ..and getting much confidence in maths .....i know i could have done better in maths in mains but i never gave time to the subject which demands most of time but i promise i will rock in maths in jee advance 2023
how was ur exam?
MEthod 7 use the concept of product of roots in method 6 to get 2/4 = 1/2
Sir if possible, please make JEE Advanced Chapterwise PYQ PDFs like you've made for JEE Mains. The PYQ PDFs are available everywhere but they are either Year-wise or filled with errors. That's our need of the hour, I hope you will consider this suggestion of mine.
Bro do you know where I can find them pls tell me
@AarushShah-ec2ce No bro. I'm in second year of clg now.🥲
During that time I had used the Marks app to solve the chapterwise PYQs
@itsmanasK is it free of cost?
@itsmanasK Thank You bhaiya it worked TYSM❤️
Wow this is sooo cool. I'm gonna try to solve maths ke adv and 2022 ke mains ke questions with such deep thinking too now. Thank u!!
amazing sir ,pls sir also bring similar for other chaps also that brush our concepts more smoothly
Meanwhile I am still solving by z = x+iy ☹
But later I did it by the 7th method using componendo dividendo rule
sir Literally mzaa aa gaya
mai Maths ke lec. nahi lgata , but apke Lagane padenge
Method 5 ❤🔥
Yes sir, today you have told a quality thing for JEE advanced aspirants.❤❤
SIR PLEASE MAKE CHAPTERWISE PDF'S FOR JEE ADVANCED PYQ'S FROM 2007-2022 LIKE YOU DID FOR JEE MAINS.... MATHONGO REALLY HELPED ME FOR THE JAN ATTEMPT AND I'M SURE IT WILL ONCE AGAIN FOR JEE ADVANCED
I have one more method, though it is similar to Method 1..... Put Z=x+iy.... Here y≠0 but there is no constraint on x so put x=0.... Hence, z=iy.... Put in the equation..... Rationalize and put Im(expression)=0
and you will get |Z|² as 1/2.....
I believe this is a much simpler and intuitive approach with minimal calculation......
hmm, did same
Method 5 is the best i will try by now to solve pyq like this
Aur bhi ak simple method hei mere pas
Vo kaha "z" has non zero img part, take real part zero , so Z= í(k), Z²= -k²
We get
((2-4k²) +(3k)í) / ((2-4k²) -(3k)í)
It is of form some complex number a/ā so multiply and divide by a ==> a²/a.ā, a² real hei tho img part=0
(2-4k²)²-(3k)²+2(2-4k²)(3k)í mei img part=0
So 2(2-4k²)3k=0, k=/=0(question padlo), so k=1/√2
Z=(1/√2)í then [Z]²=1/2😁😆
Yeha í means iiota
IQBAL SIR 💘
XYLEM💥
🔥
Yes mam every session and dpps are done mam 100min dialy doses are done 🔥
Anup sir perfectly knows what students need
I was bit worried about adv 2023 and here's sir to help us
Bro iitian h kya??
Method 2 as later k methods might be easier but sochne me time lgega..
But method 2 is easier and very commonly used property
And 2nd last way I loved too
I will work hard in learning mode in advance questions......❤❤
Le me who has left complex numbers💀
Especially put -1,by observing that one small difference
now i am able to solve 2020 paper questions easily
i mean 2022
Thank you 😊 very much sir for this
I was shocked when sir said to think about another I assumed it to be -1 and very next moment it was so really a good hit and trial😇😅😗
M8 vectors ,angular bisecter concept, the best method no hit and trial yet solved in a minute
16:40 sir, how did u do z^2 to be |z|^2, waisa to real mein hota hai
Sir please more videos like this for maths🙏 very good explanation 😃
Sir, we have another method for solving this, much similar to the last method.
As mentioned, Z should is an CN with non zero img part. So, just assume Z=ai, a-constant. And the above eqn is a real no, so the img part again should be 0 both the sides. And we let the real part be any no, let x. This x comes out to be -1 after solving, and hence value of Z also comes out to be 1/√2i. This is a superimposed trick of last 2 methods, ig.
even simpler method would be ki after nr+dr/nr-dr separate z and another term 1/2z comes,so this kind of gives us a hint ki mod z sq is 1/2 simple
The last hit and trial method u could have got tht real number to be -1 but taking z to be purely imaginary(instead of hit and trial) after all they only said imaginary part was non zero they didnt even talk abt real part
Sir today video is liitle bit dark. Increase brightness 🔆 next time
I will work hard .
What should be the approach to solve 2022 Mains problems…..I am facing difficulty in them even after completing a chapter
Yes bro same
They are tough af😭
method 8 jisse 2 second meh hogaya , put z=ki , usse 2-4k^2 +3ik / 2-4k^2 -3ik , ab since real, maine 2-4k2 = 0 krdiya , usse mod z ^2 = 1/2 aagayi . It clciked when they said imaginar part isnt 0 , toh purely im rakhdiye
Brilliant solution sir😊😮❤❤
When I saw the ques here ,firstly I thought let's try to form quadratic😁 ,thankyou sir ,watching this analysis was worth it
sir when Jee Adv 2023 test series will be launched?
Sir ur doing great, please launch jee adv coruse in January 😇.
Proud to be a Xylemian🔥
💥
Thank you sir ❣️
Sir which book provides pyqs with different methods
Thank you very much sir please make more videos like this sir so that we can strengthen our concepts
All the methods were AMAZING but THE SECOND LAST was THE BEST
Take z simply as an imaginary no. As nothing was said about the real part... Then too it goes similar to M-1 yet a lot easier
sir Compenendo dividendo which makes a short complex number
Sir another method is to use componendo dividendo followed by putting 1/z = z bar / (mod z)^2 and equating imaginary part to 0 to directly get answer.
5th method dekhkar goosebumps aa gaye...!
Iqbal sir 💚
Method 5 was 🔥🔥🔥🔥
This similar type of question was in our class notes (obv before adv 2022) and our teacher taught us Method 3 there, so idhar bhi mujhe M1, M2 and M3 most probably strike hue they, but best method for me in an exam hall would be M3 (coz vahi strike hota mujhe😂😂)
BEST complex no. one shot...ever😂🙃
What an amazing video. It's kind blowing especially last method. Tysm
I knew till method 2 and was amazed by method 5
Constraint only on the imaginary part so we can assume z=0+bi, and solve. (sorry if this method was already told by sir, just saw the last method)
Sir chapter wise mock dena chahiye ya pyq as mock?
If we put 1 in last method, we get 0
PLS HELP
yes lol
Yes but we won’t consider that because it is given that Z has non zero imaginary part
Thank you sir, you are amazing
sir what about the mathongo pyq book?? will it be available by this sunday?? and will it contain every maths question of 2019-2022 with solutions??
Sir I was able to figure out the last method,so happyyyyy
Put t=-1 in hit and trial, solves instantly
sir we can do so but tym bhot lgta hai ese har ek ke mathods ko sochne me like if u can tell any standard tym?
Sir I can say there are 7-8 questions in MAINS which can be solved by cheat method i always use it though not proud of it😅
If in the same ques it said purely imaginary we will take the whole to be 1 right?
Sir Mera Syllabus 20 Dec Ko khatam ho rha hai but practice around 20-25 % hain kya karu main abb please bataiye or konsa material solve kruu
Sir aap bohot help krte ho meri
Sir at the first time I have solved by method 5
Advanced pyq are very imp as there aren't a lot of advanced q
so we must make the most of every q
Thank you very much sir
Method 5
just wow😮
Put z=iy within 1 min u get ans
Sir always put the actual picture of jee maths in front of us
It keeps getting better.
Sir jee mains ke bhi questions ase hi solve karne h kya
How to prepare for jee advanced and cutoff pls sir jee advanced decoding video pls sir and thanks for always help ❤️
I had got the 6th trick but when I got z^2 = -1/2 I thought how can a square be negative and then unpaused the video... And what I found ???
You guys know that..
thankyou sir for marks app, i have completed top 500 questions
Last step was totally absurd that it even worked 😂😂
Sir yeh hit and trial...is not that reliable because if I assume the real number to be 1 then you are not getting the answer...so I would suggest not to pick the cheat method
But sir if we think every question with different methods it will consume almost 2 to 3 times more time.......
Sir please make a video explaining tpc, given on information Bulletin page 45 and appendix IV
jitna mai pata kar paya... ye cheez 2018 ya 19 mein laye the aur fir shayad bhool gye ki aisa kuchh hai... kyunki nta site pe mujhe to koi option nhi mila as student register karne ka
@@Fivekey100 classic nta move
thanks
with pen and paper
Method 5 . Apne kya socha hai
Sir can we solve every pyq with more than one method
Thank you sir
Where does Respected Iqbal sir teach ?
Is he a member of your Department ?
One more method of taking z=iy
last two methods op op op op op op op!!!!!!!
Me who is able to solve advanced pyqs but not able to solve 2022 Mains pyqs ( Maths ) 🥲
Sir could you pls lauch a Course where you could teach us how to solve a question using different methods
