i got 3x +2z -z = 1 or somethingDid people get the equation of the plane as something like 5x+4y+3z=15 ????? Please answer
did u get i + 2j + 2k as the position vector of D

I remember all the questions.
1. Gradient of the curve (3)
2. Logarithms + Modulus (5)
3. Integration by parts (4)
4. Parametric Equations (6)
5. Trigonometric Identities + Integration (7)
6. Iterative formula (8)
7. Partial fractions + Binomial Theorem (10)
8. Complex Numbers (10)
9. Vectors (11)
10. Differential Equations (11)
That totals up to 75 marks....but I'm not very sure about the marks distribution. But this is what I can kind of remember. Please post your answers question by question so we can compare
For ques 2, did you get 2 answers? One positive and one negative :s im not sure if i had to reject one..
How did you go about solving equation of the plane?i got 3x +2z -z = 1 or something
did u get i + 2j + 2k as the position vector of D
How d
How did you go about solving equation of the plane?
Did the same thingfirstly i found AB and AC . then i worked out their cross product which i guess was, n= -9i -6j +3k
then r.n = a.n ( where a is A , B or C)
and you got the equation =?Did the same thing
I did the same thing! But I don't know why our answers aren't matching Yours is probably correct though. I did mine in a REAL rush, so I think I must've made a mistake :/and you got the equation =?
Unfortunately i dont remember..but i know i made a mistake somewhere while using cross product.and you got the equation =?
I couldnt understand the second part of the question for complex number :s i just made a circle with radius 1 centre -i i think..i attempted to solve the arg , but i got confused..so i just left that partI didn't even attempt the other qs in vectors. Left out the complex nos also. I'm soo screwed and I have an A in AS Math. All to waste
A girl happily said it was really easy when the papers were handed over to the supervisors at my centre.i wonder who found the paper easy . actually it wasnt all that bad, to me only the time provided was a negative factor.
For integration I got 4ln(something) -4
For iterative I got 0.93
For complex I got 1+2i and -2-4i
for binomial I got something +17/72 x^2
and lastly for differential I got 49.4
i got 3x +2z -z = 1 or something
did u get i + 2j + 2k as the position vector of D
For partial , i think i got -1,-1 and maybe 3 for values of A ,B and C :s
If the gt is low , then yes . Dont worryGuys with all the confusion i have and the qstns i have left i think i will get about 45 to 50 marks is it going to be enough to score an A or a B?
