Mathematics: Post your doubts here!

[A star]

if i had my scanner working .... i would scan it .... i got a book ... and i am SURE it will come this year ... and saay i didnt tell u !!

well i cant understand but just tell me which paper it belongs to as it looks like pure stats and mechanics :/

 

[ahmed abdulla]

its pure maths 1 ??

yes

 

[A star]

they dint -_-

no worries u got into uni and ur equilance was outstanding mine in o level is 85 :/ i still have to go through that terribly anxious time :/

Please help thank you!

so no one knew how to solve the question !!!
as i said it was challenging

Please help thank you!

what question paper is this?!!

The answer equation you have given is incorrect or you are missing something out of the question..

if T1 = 2 , then T2 = 2*0.75 or not? Just answer me this. If it is Then what I have done is correct.

Verify this for me.
a = 2
r = 3/4
n = n ?

a)
Sn = a(1-r^n)/1-r
Sn = 2(1-0.75^n)/1-0.75
Sn = 2-2(0.75^n)/0.25
Sn = 8-8(0.75^n)

b)
Sinf = a/1-r
Sinf = 2/1-0.75
Sinf = 8
Can't be greater than 8.

your very fist step is incorrect !!!
T2 will be 2*2*0.75 ... as it goesdown and re robounds ... exacly like mecahnice when it goes to max height

yes the same point struck me from the bigening but coulnt apply it to the equation to get the answer

See, I don't have mechanics so I don't know that. If it were simple GP it would have been solved the way i was doing. Now it includes M1 stuff and I don't have M1 so I don't think it would be coming in the paper since some people opt for S1 and S2 and are Commerce students and have never studied physics at all...

yes but no harm in attempting it

ik man but i mean which paper which year cuz i solved it but i don't wanna give u wrong answers so i need to make sure what i made is right first..

BRO ITS P1 ONLY ... but it has got a relationship with m1 ,,, there is a big chance of it coming as i said before

Like I said before. Not everyone has studied physics before, I have never seen a question like this in maths before, apart from mensuration (area/volume formulae) which requires some extent of basic physics knowledge.

Commerce students with S1/S2 will be at a disadvantage with a question like this. that's all that I am saying.

It can't be solved with a simple AP/GP formula. since what we use to calculate terms is a(r^n-1) while in this it becomes 2*a(r^n-1)

while for sum it is Sn=a(1-r^n)/1-r .. For this It can't be used .. No matter how many changes you make.

2(1.75-2(0.75^n)/1-0.75 is what it is becoming .. in it's simplest form..

where a(1.75-2(r^n)/1-r) is what the formula is becoming... Now if you mechanic peeps can go somewhere from here.. that'd be good..

All I can is it ain't a ordinary Progression question.. and it won't be coming in the paper.
