[sparten]

since the wait of 24hrs after the paper is over can any one list all the answers 4 paper 32?
cheers

Q1 logs 2.30 thats as far as i remember

 

[mukki]

q10 vectors i dot product of l direction and planes normal proves to be 0 ii 5,3,3
iii distance 6 (dont remember possible positions )

What was the solution of the differential equation? Was it y = ln(2/3-e^2x)

Guys, I will get a copy of the exam from my school in a couple of hours (once the 24 hour mark is complete) and my tutor will come this afternoon and solve the paper for me, I can tell you all the answers tonight

it vl b so nice of u

answer for volume part was pie/2(e2-1)
for iteration part was 1.32 as far as i remeber.
two stationary points were 15 and 75 degrres,too bad i gave answers in degrees they were suppose dto b given iin radian
in complex part u was 1/2 +1/2i
in vectors part 2 lembda was2

what was question 5 and 6?

 

[sparten]

what was question 5 and 6?

q5 was identetity
q6 was abt stationary point

 

[Bushrafareed]

Do you remember which identity ? i guess i missed this one? was it something like sin2x?

 

[2pac]

does anyone remember the complex number question?I remember plotting -.5-.5i on the argand diagram.

Are you sure of the lambda thing? I think it was 3? And i'm not sure about the other value of lambda?

Does anyone remember the last question? NOT THE ANSWER, THE QUESTION?

Q7 i 1+3i/1-2i =u , simplify
iiplot a b c where a=u b= 1+3i c=1-2i
iii)prove that 4pie/3 =( tan^-1)(2) +(tan^-1)3

 

[Bushrafareed]

i'm not sure it was 1+3i or what and whether part iii was tan^-1 (1/3) or (tan^-1)3

 

[beststriker]

i) was the ans to the complex part was -1/2 + 1/2i ??

 

[beststriker]

In the 1st question, the value of x was 2.30 and in the vectors ques ii) part, the lamda was 2. correct me if i am wrong.

 

[solidboy123]

Yaar according to some toppers and me the only answer to volume question was 1 by 4 pi e^2

 

[Bushrafareed]

i) was the ans to the complex part was -1/2 + 1/2i ??

yes..

 

[aaditya menon]

i'm not sure it was 1+3i or what and whether part iii was tan^-1 (1/3) or (tan^-1)3

part iii was tan inverse of 3.

And beststriker - yes, i think that was it if i remember correctly.

does anyone know q 5 and 6?
