    expected grade boundries for As math p12

    Ah yes. That's true. So if I did that wrong but part of the method was correct, how many marks do you think I could loose?

    expected grade boundries for As math p12

    First of all that is axiomatically wrong. I'll agree that you had to consider BA but OC was ( 4 5 6) NOT ( 8 4 -8)

    The ratio was not equal to 1 yes. What kind of an equation did you solve. The question was: The 1st, 2nd and 3rd terms of a geometric progression are the 1st, 9th and 21st terms of an arithmetic progression. The first term of both is 8. The ratio is not equal to 1. Find the common ratio.

    The equation of the tangent of the graph (8 - sqrt(4-x)) was y = 0.5x +5.5. However if your method was partially correct you will get M marks and yes there is an ecf in P1

    Okay yes, now I remember the answer. CD was ( -8 -4 8) and since OC was ( 4 5 6) then OD was ( -4 1 14)

    expected grade boundries for As math p12

    yes Q2 (I)(a) was sin p= -sqrt(1-k^2) and tan p was -(sqrr(1-k^2))/p and sin2theta will be negative becoz sin theta will be negative and cos will be positve so sin times cos will always give a negative answer. This question could have been done very easily by those who have studied p3

    Q1. (3.5,0) Q3. -145 is the coefficienr Q4(a) p=2,(b)perimeter was 34.1 Q5.(b) theta=116.6, 296.6 Q6(a) r=1.5 Q7 was vectors. Q8.(-2,10.83) this question was checked using an online graph calculator so it is absolutely correct in Q9 was 0.583 Q10 value of p was -4

    Recommendations for a good scientific calculator for AS Maths?

    Well 991ES plus is very good, but personally it makes your work way to easy. If you really wanna be good at mathematics, you should know how to do the work yourself as well. So a better one to use would be 82ES PLUS

    You do not have any reason to worry. Candidate answer booklets are scanned but the marking software used by CIE examiners called SCORIS, allows examiners to take action when they find out that the candidate has written outside of the designated answer space. Examiners send the answer for review...
