[@Rahul_Singh1729]

My thoughts before seeing the solution 3:29 Vn method ka basic principle yhi hai ki aise do terms bane jo series ko continue bhi rakhe aur subtract hokar apne agle ya pichle term se katt jaye. Agr yha next aur previous element ko bhi le aaiye like r(r+1)(r+2)(r+3)[r+4-(r-1)] krke 5 se divide krde toh ye series continue bhi ho jayegi aur terms katt bhi jayenge. Bus iss baar khas baat ye hai ki (r+4) wala term apne agle bracket ke 2nd term se katega so r = n bachega, aur (r-1) wala r = 1 pe bachega, basically 0 ho jayega. Toh answer n(n+1)(n+2)(n+3)(n+4)/5 aayega. Major takeaway yhi tha ki series ko continue bhi krna hai aur 2 parts mein break bhi krna such that ki wo kat jaye. 5:36 I mean ye dono toh easy the, video khatam krne ke baad kyu solve krna? Simply numerator ko (r+3)-r likh do aur 3 se divide krdo. For break krke solve karenge toh 1/18 - 1/3(n+1)(n+2)(n+3) aajayega. Iss mein n tends to infinity krdenge toh 1/18 aayega answer. 6:29 ye nhi bana khud se. Kaafi socha but mai soch hi glt direction mein rha tha. Mai kbse ye soch rha tha ki kisi tareeke se (r+1)! - r! Mein break krdu but fir wo r^2 panga de rha tha. 6:58 your approach was amazing bhaiya! Waise apne whi Vn wala thought diya hai ki series ko continue rakh ke aise banana ki terms katte chale jaye. Mere dimag mein ye click nhi kiya ki (r+1)! Aur r! Ke aage bhi aise terms aajaye jisse ek series ban jaye tb bhi koi dikkat nhi 8:42 ye wale mein mai iss step tk pahuch gya tha but fir laga ki ye method glt hoga toh kuch direction mein sochne laga ;-; Waise mast question tha ye maja aaagya. Iss question mein mai itna smjh gya tha ki 6^n ko neeche Lana padega, but jb (2/3)^n jaise expressions aane lage toh laga ki mai glti kr rha hu. Abse pura end tk solve krunga. Although exam mein aayega aur aisa question kbhi dekha nhi toh chorna hi padega. 9:08 3 aayega answer 12:00 ye mein mera approach yhi tha ki root(2) = 2sin(pi/4) = 2cos(pi/4). Ab aise A1, A2, A3, A4 nikalenge toh usse whi relation prove ho jayega jo Diya hai question mein. Baaki limit wale ka answer pi hoga. 12:16 ye toh kaafi common question hai, mere coaching material mein bhi tha. Easy hi hai ye bhi 13:52 ye bhi same pattern pe based tha. Simply first aur last term ko add krne pe constant ban rha hai. Yha total even number of terms hai kyuki n = 0 se start ho rha hai toh saare club ho jayenge aur 974/(2)^1947/2 aajayega 14:33 ye repeater sun kar relatable kyu lg rha hai? ;-; 15:27 easy tha, same approach pehle 9 se multiply divide krke 10-1 + 100-1 … krke break krdo. Fir gp ka sum laga kr answer 16:01 ye dikhne mein tough lg rha tha but hai easy. Basically given series ko khol kr likhe aur odd aur even terms ko ek jagah krle toh ye question whi khatam ho jayega. Bus even terms mein se 1/4 common nikal lo and we will get our original series back. Bus waha se pi^2/8 answer aajayega 17:00 videos toh kaafi achi hai bhaiya! Bus last mein video related kuch tough questions de diya kijye jaise apne quadratic mein diye the jinko humlog khud se solve Kare. Aur wo Trigo substitution wala questions gayab tha usko channel pe post kar dijye please.

[@jeesimplified-subject]

Aree bhai bhai, next level devotion! read it all. 05:58 Yes easy ones ko man me karke Aage badhskte ho. 6:58 Haan this question was a little diff from traditional factorial style 08:42 Yaad rakhna, aisa manipulation karna seekhna hai speed se, JEE Adv Tak important hai. aur ye tab hopayega jab practice ki quality and level of question will be insane 16:01 Iski ye video dekhna kabhi maza alega bohot - kzbin.info/www/bejne/ml7SZJh4btiZotUsi=p1DuHlKKuvIMWo-4 17:00 Yup, will drop some good stuff in the end, also pref so60 for that.

[@Rahul_Singh1729]

​@@jeesimplified-subject Thanks alot bhaiya!! Ha wo manipulation skills ko strong karne ke liye I'm doing hall n knight higher algebra book (vikas gupta sir ke guidance mein padh rha hu toh unhone selected questions diye hai) aur saath mein unke sheets mein bhi kaafi ache questions hai (black book ke author for a reason 🗿) toh usse bhi understanding develop ho jaati hai. Saath mein aapka concept crunch series aur maths unplugged ka idea series is like a cherry on top! Wo 3b1b wala video raat mein dekhunga padhne ke baad :) Again thanks alot bhaiya for your efforts!

[@anonymous8s640]

Thank you so much ! Pls bring these type of vids for toughest topics in each chapter Like sum of special series in binomial theorem

[@sujal1869]

This was a literal god level crux of sequences, got to know new things but ig there was something missing in the trigonometry part. Overall it was amazing. One thing you can do is increase the no of self try questions(good for building confidence, thought process and accuracy). Overall it was best and thanks for the video.

[@jeesimplified-subject]

Means a lot, keep drilling brother.

[@NisargShah-xb2zj]

[@NK-bo7lt]

6:00 Bhaiya vaise mera method thoda alag tha and thoda complicated bhi kah sakte ho. [r^2-r+1]r!----> r^2-r+1=[r+1]^2-3r [r+1]^2.r! -3r.r! Phir maine ek sigma mein [r+1]^2.r!-r.r! Rakha Further [r+1].[r+1]! -r.r! Bana liya aur ye solve ho jayega Vn se Phir second part sigma wala 2.r.r! Rakha ye to easily r ko r+1-1 likhne se ho jayega .
