i would like to advise you bro!
This kind of questions , from the text book are VERY complicated ,
and according to our exam point of view , not very hard question are coming ..
so what i advice you is to , do pastpapers ONLY ... this questions squeeze your mind for nothing!

Thanks a lot bro, really appreciate it.
I'll be grateful if you could also help me with no. 5(i) of the same paper (October/November 2008). It looks pretty simple, but I'm getting the remainder as: 3x+(a-6).. and I can't find the value of a using this remainder. Please help!

Thanks

Hi again,
i stumbled upon the questions (8 & 10) attached and i couldn't solve them, i asked on different websites, i searched youtube, searched the web but none explained what should i do and how should i solve them, i'm also studying at home by myself and i don't have a teacher to ask so if someone can help me solve the question and more importantly explain it to me that would be graceful!

where should i study my stats from?

 

[Anonimous12345]

(i) Pythagoras → OT = 13, QT = 8 cm
Angle POQ = tan–1(12/5) = 1.176
S = rθ → 5.88
→ Perimeter = 25.9 cm

Hello I'm uploading a question of paper 1 of maths and it seems very accessable however some thought is missing as I can't solve it out. In the markscheme it says that tan^-1 (12/5) would give 1.176 and I don't understand this. Can someone explain me plzzz.

I like the doubt it made me think for a while so here's what i did
for 8) i found the sum of n=1,n=2 and n=3 i could keep going just to be more sure but 3 are enough
i found sum of 1st n terms is -1
sum of 2nd n terms is 4
sum of 3rd n terms is 15
as we know sum of 1st term is -1 that makes it obvious first term is -1
so we have -1,y,z
y and z are 2nd and the 3rd term respectively
as we know sum of 2nd n terms is 4 that means -1+y=4
and so for the 3rd -1+y+z=15
we will get y=5 and z=11
we have -1,5,11
now lets see if its AP or GP
if its GP then un=an^(n-1) lets try that out
5=-1*2^(2-1)
5=2 that is wrong And by now you will know its not GP
lets see if its AP then un=a+(n-1)d (d is the difference between the terms here ist 5-(-1)=6)
5=-1+(2-1)6
5=5 hence proved
you can try for the 3rd which will be
11=-1+(3-1)6
11=11
For the next question you asked you should do the same but if you want me to do it i will do it by the way the first term is 1 and the common difference is 4
I hope i helped and if i did you always free to ask more questions
