f(x) = a(x - p)^2 + kdone but no help why dont u try to solve it and see if u can get an equation?>
Now plug in values from the graph:
4 = a(0.1 - 0.3)^2 + 8
a = -100
f(x) = -100(x - 0.3)^2 + 8

i) Fit 2 cosine cycles in the stated domain. y = 1/2 is a straight horizontal line passing through (0, 1/2).http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_w11_qp_11.pdf
Please help me solve question no. 3, I do not understand how to do it.
An explanation will be appreciated.
Thanks a lot!
What's stated in the question is the length of the side of triangle ABC. Length AB is not equal to length AQ. You have to use Pythagoras Theorem to find r or AQ.http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_s12_qp_11.pdf
In no. 3, why is the value of AQ the radius of the sector APR? As stated in the question, isn't the radius 2 cm?
Please help!
i did tried to solve this way but it gives only vertex plug in 0 or 0.6f(x) = a(x - p)^2 + k
Now plug in values from the graph:
4 = a(0.1 - 0.3)^2 + 8
a = -100
f(x) = -100(x - 0.3)^2 + 8

I'm aware that you are supposed to find the length AQ using pythagoras theorem.. but I don't understand why AQ is the radius of sector APQC. The radius is 2 cm right??What's stated in the question is the length of the side of triangle ABC. Length AB is not equal to length AQ. You have to use Pythagoras Theorem to find r or AQ.

the question isnt 4rm a paper, its a homework we were given n i rechecked it, itsexactly the way i wrote itI think you made a mistake while copying the question because the first angle comes out to be 37.8 and that is not a mistake but the actual answer using your values. Would you mind checking or perhaps attach the paper?
The question is in http://papers.xtremepapers.com/CIE/...AS Level/Mathematics (9709)/9709_s06_qp_3.pdf and it is 4(ii) detailed solution please.the question isnt 4rm a paper, its a homework we were given n i rechecked it, itsexactly the way i wrote it
