[abbey789]

i guess root 8 -2i

I even go that

 

[abbey789]

what was the question of the complex no , i cant remember it , could u help remember it so i can remember my answer :S

I guess it was 9

 

[freezingfires]

I got
y-2z=7

Well I think the equation was x-4y-z=12( b=-4 c=-1 and d=12)

 

[freezingfires]

What were the values for A and k? for that lny vs x^2 graph!

 

[terry jefferson]

k=0.42 and A=2.23 or somethin like that

 

[terry jefferson]

anyone got fractions for b and c for the plane equation?? and i got d as 28/3....damn if i get that wrong im screwed

 

[Doggybros]

post the answers to these questions when you get them.....i have doubts in only these ones....

I don't think you read my post correctly, I said I could solve NONE of those.

yeah man....i said when u get the answers from someone else post it....u asked ppl to PM u rite??

Ya ...I got in fractions...something 28/something. And 37/***......I conformed it in calculator and angle was coming 60 degree

inbox me, if anyone want to discuss the paper

 

[sagystu]

I guess it was 9

no i meant what was he asking the phrase of the question .

 

[sagystu]

any one knows markscheme ... handwritten ones drafts ?

 

[abbey789]

no i meant what was he asking the phrase of the question .

It was about complex numbers. If iw=w^2 or something like that

Q6 ka answer was something like LN [(3 + or minus 2rt3)/3] It was correct cause I checked it in the calculator.

I got two angles in question 7. First being something like (360-25.26(w/e the angle was) - 71. something (the alpha). Second angle was 360 + 25.26 - 71.sth.

Due to time constraints, I couldn't manage the last part of vectors and was unable to substitute the Y into the initial eq in q5. So I guess, raw marks I'll obtain are somewhere around 63, give or take 2.

Can anyone confirm the answer to the second part of Q9, the greatest distance? Was it rt8 + 2?

yeah i got the same ans for q9..........in q7 why do we use 360+25.26-71.57.........? dont get it

 

[Nafee Papers]

is the answer to the differential equation (25/36)e^1/2.......?

 

[Nafee Papers]

It was 3.70 they asked the answer to 2 dp

how did u get it?

 

[abbey789]

yeah i got the same ans for q9..........in q7 why do we use 360+25.26-71.57.........? dont get it

because when you do 26.5-71.5 then you get -45 So to get the angle as it is cos you dp 360-45= 315

 

[Thampi4]

Wat ws da answer for the maximum point?? Was it square root 3a.

Same

 

[abbey789]

What were the values for A and k? for that lny vs x^2 graph!

k=0.42 I don't remember A's value

 

[abbey789]

Same

how did you do 5? I got stuck after 3x^2+y^2-6ax=0
