Mam jo previous topics ap ny krwa diye hoty hain un ka kindly aik bilkul short sa idea de dia krein jo next exercises mai use hoty hain,jesy idher convergent or divergent it`s a request! or kia Q9 or Q12 ending waly steps mai change is liye hain k 12 mai telescoping series hai or 9 mai nahi? please reply
mam Q12 me telescoping series kuen nhi bni ??and ma hmein kese pata chle ga k kaha pr telescoping series bne gi or kahan nhi ??? and mam Q12 me k=n se pehle n-1,n-2,n-3.. ki values kuen write kin????
Agar sari values, cut rahi ha, except first value and last value, then it is telescoping, otherwise not. And Q12 ma is liyay likhi , so that hamain clear pata chalay Kay kon kon si values cut rahi ha or kon kon si Nahi.
Good question, I explained same query in that question, I know it can comes in mind of students, so I already explained it there, watch that question carefully, you will get it insha'Allah.
Mam Q9 me values upto infinity thi and also in Q12 ,and in Q9 Sn =infinity but in Q12 Sn =1/3 why?? as both series are upto infinity then why both series have sum = infinty???
mam question 2 me jo ap ne geometric series find krne k lie jo formula use kia hai vo kahan se aaya ??? bcz previous exercises me hm ne geometric series find krne k lie jo formula use kia tha vo book k page 136 pr dia gya hai and that is different from this formula,why??? plz clear my onfusion formula on page 136 Sn=a(1-rn)/1-r formula used in 4.8 Q2 Sn=a(rn -1)/r-1 these are diffferent....
Both formulas are essentially the same, so you can use either one. However, we usually prefer one formula when and the other when . By taking common from both the numerator and denominator, they cancel out, simplifying the formula.
@@learnmathandrise922ok mam thank you ,it means new formula is derived from previous formula ?? And they both are same just sign convention occur??.. am I right?
Mam aik qs h kindly reply hum ne qs 11 ma k-1,k-2 ,k-3 kio lekha I mean ke hum ne pechle qs ma kio nhi lekha.or pechle qs ma sirf first and last value bachte the ais qs 11 or us ke ma 3 values kio bachte hain. Plzzz explain😊
There are two formulas: one for r greater than 1 and the other for .r less than 1. However, both formulas are essentially the same. By taking -1 as a common factor from either the numerator or denominator in one formula, the negative signs cancel each other out, transforming it into the second formula.

it`s a request!
or kia Q9 or Q12 ending waly steps mai change is liye hain k 12 mai telescoping series hai or 9 mai nahi?
please reply
Yes beta
Thank you ma'am ❤❤❤❤❤
Most welcome 😊
Ma'am First question ka answer shayed end mein ghalat hougaya 12:19
Yes , n comes with the answer. Missed by me .
@learnmathandrise922 Okay No problem I was trying to clear confusion among other students although I know there's mistake
Other students, really
Thank you best lecture
Most welcome
mam q7 me apne 1/3[1/1-1/3n+1] second last step me kya magar question 10 me direct first term ko last se minus kya aiska kyun?
Besttttt lecturer, thank you sooo much ma'am ❤
Most welcome 😊

@learnmathandrise922 ok mam thank you so much...
mam Q6 me Tk-1 pr jb summation apply kia hai to ap ne bola that k=2 but as in Tk summation values start from k=1 so for Tk-1 ,k=0 kuen nhi hoa ???..
Good question, I explained same query in that question, I know it can comes in mind of students, so I already explained it there, watch that question carefully, you will get it insha'Allah.
@learnmathandrise922 mam I watched it but still confused (don't know why)..
Mam Q9 me values upto infinity thi and also in Q12 ,and in Q9 Sn =infinity but in Q12 Sn =1/3 why??
as both series are upto infinity then why both series have sum = infinty???
Beta in my video of exercise 4.5, watch intro of convergent and divergent series. You will be clear, it is important topic.
@@learnmathandrise922 ok mam
Ma'am plzzz jaldi upload krden . Sendups Han 10 SE or 5th chapter a rha
Jazakallah Ma'am Samrina, you are a great help indeed, lots of appreciation, love and regards❤
Jazakallah khair 💖, stay blessed always ameen 💞

Mam we need your prayers for exams
Final exams are still a bit far, but the pre-board exams could be in February. Wishing you lots of prayers and immense success!
Aameen Thanks mam ❤
kindly uplooad 9.1
Kindly upload video of chapter 6
Ok beta insha'Allah
Assalam O Alaikum Mam ...Mam final board kk exams kb tk hon gy 1st year walon kk ? PLZ bta dyn
Tentatively in the end of March
mam question 2 me jo ap ne geometric series find krne k lie jo formula use kia hai vo kahan se aaya ??? bcz previous exercises me hm ne geometric series find krne k lie jo formula use kia tha vo book k page 136 pr dia gya hai and that is different from this formula,why??? plz clear my onfusion
formula on page 136 Sn=a(1-rn)/1-r
formula used in 4.8 Q2 Sn=a(rn -1)/r-1
these are diffferent....

Beta, Jo telescoping series Nahi Hoti , UN ma zyda terms find out kerni perti ha, ta Kay ye clear ho sakay Kay kon kon si terms , cut Nahi ho rahi.
Jo telescoping series Hoti ha UN ma surf pehli or last term bachti ha. Beta, do watch whole video, you will be clear insha'Allah
Thank u ma'am❤
Mam apnay 1.3 karwa di hai ?
Yes beta , first 4 chapter and 8.1, 8.2 are uploaded, kindly go to play list and watch 1.3
Ok thank you 😊 mam
Book me Jo geometric series ka sum ka formula ha us me numerator and denominator dono me 1-r ha aur unke exponents waise hi ha. Apne r-1 Kyu likha ha

@@learnmathandrise922 so can we use the formula written on book in this question?
Yes y not, both are same formula, you will get same answer.
