Sir the method is good, but as a student I will get very nervous & underconfident in the exam hall to put the value q=1, when the question strictly restricts it but I can definitely use the 2nd solution. Thank You
Sir didn't just put q=1 He just took the limit where q→1, and we all know that q=1 and lim(q→1) are entirely different things. So the first solution is also correct alternatively.
Sir i do agree with you method but sir limiting value nikalne wali trick ham hamesha use kr payege....kya kabhi kisi case mein problem bhi aa sakti hai?

sir we can directly put q=0 also which gives also fast answer
@milindbathla usmein tn mein 1/2 ke powers ayenge to jyada complicate hojayega
@@kushal327 bro we can use gp formula to simplify
@@EduPurpose-n9z yes right
@@EduPurpose-n9z par (-1) le liya to gp ki bhi jarurat nahi
gp defined nhi hogi lekin

i totaly agree limiting value rakhne mein confidence nhi aayega paper mein but q=-1 is best aur kiya bhi jaa sakta hai
Think like examiner ❤ Ye mene kabhi sochatha wow😮
We can also understand that T100 will have power q^100 and s100 is the only term q^100 so we can directly compare powers and get that alpha= 2^100
Once again thinking marvel
Sir you are making my maths super strong
Super insights
Ekta do question bhi agar wise ho Jae actual paper mein to hazaro rank ka fayda hoga
sir we can also solve by comparing coeff of highest power term of q
Nice method sir
Beautifully solved
Can't we put q=0
I think it will work and it does
@I_SsTW_W yes we can do that way also!!
And it is easier than this method
yes, it does work.
Ig it'd be more lengthier
can compare coefficients
sir please bring more videos like this
Can we not put q=-1 ??
Video toh pura dekhle

@himankgupta3310 nhi aaygi until us value pe abnormal behaviour hai like undefined vgera
Sir pls vectors ke long soln.ke easy methods daldo🙏🏻
Namaste sir I bought pratham dlp will I be able to access pyq express because it is not showing in app.
Love you sir ❤

q = -1. Single step.
thank you sirji
Sir, I put q =0 and still got the answer....is it a favourable approach
maza aagaya sir
put q=0 and then Sn=1 also T(100) can be found by GP summation and after that lastly we can find alpha by neglecting 1 against massive power of 2

what?? this is exactly why 1 should be subtracted.
nC0 + nC1 +nC2....... nCn = 2^n
(nC1 +nC2....... nCn) =(2^n - 1)
ryt?
Baby q ko zero rakho aur fir S mein gp lagao aur badhiya. 16×2=8.
