thr he have taken y=1, whreas in ur ques it was y=1/2Thank you very much!
thrfre just telng u , tht acc to the ques, u wll gt 4 roots... not 3.

can u please post the link??
just find the dy/dx of the eq. it will be as follows:
Now I'm clear. Thanks a ton buddy !I remember doing this question, and getting it wrong lol. Convergent means like the GP is going to a number but it never actually gets to that number, like you know when r of the GP is less than 1 and you have to find the sum to infinity, thats the number that it approaches but it will never get to that number! So basically you will say ((Second Term of GP)/(First Term of GP)) < 1 . Then you solve that equation that you get...
yep
Yes it is and I hv solved it alsoYour working is right, but the Number of terms between 7 & 13 should be 7, not 6. If you use that the sum = 203 which i think is correct
Are you sure, i doubt it. Like even if you do it without using a formula (getting all the terms up to 13 and then adding from the 7th to the 13th) you won't get that answer :/
Alright, how did you solve it?Yes it is and I hv solved it also
d=-3-(-7)=4Alright, how did you solve it?
ok but the timeperiod is 360 so it completes one rotation at 360
ok but the timeperiod is 360 so it completes one rotation at 360
Ok man, u hav 2 use the UV method 4r this and differentiate in terms of x.can anyone differentiate ths xy(x+y) plzz???
d=-3-(-7)=4
7th term = a+(7-1)d=
=-7+(6*4)
=17
30th term=a+(30-1)d
=-7+(29)(4)
=109
Now a=17 and l=109
n=30-6=24
Sn=n/2(a+l)
Sn=24/2(17+109)
Sn=1512
yeah our bad ialso read 13Ohhh, my bad!! I thought you said 13th instead of 30th, i guess i read it wrong in your original post Yeah, you are right!
Frequency is determined by B for eg in Cos2X the time period will be doubled in 360....ok but the timeperiod is 360 so it completes one rotation at 360
Lol it's okOhhh, my bad!! I thought you said 13th instead of 30th, i guess i read it wrong in your original post Yeah, you are right!
