PURE MATHS PAPER 32

[AvgStudent]

How was it? Difficult? Easy? What do you expect the A boundary to be?

 

[Sid200799]

Paper was pretty easy except for the Vector question. When i discussed with my classmates, everyone was getting different results so idk
How was ur?

who else got the distance from A 1 unit?

 

[Abysswalker98]

who else got the distance from A 1 unit?

I got 1/(under root 3).

I think the paper wasn't that difficult (especially since he first several questions were quite easy). Unfortunately, I messed up the first part of the complex question.

The argand diagram was shaded upwards like WITHIN the circle and ABOVE the line right? And did anyone get 1/28 pi^squared + ... or something in the last question?

yes shaded upwards!

Distance of A to plane was 1/√21 and eq of plane was -x-y+z=0
Last part answer was pi square/32 - 1/4

 

[Qaussain]

Argand Digram,
Dotted circle with centr 2, -1
Dotted iss liya because |z-u|< 1
Region shaded was upwards

 

[Sid200799]

could someone plz explain how they got the equation of the plane \?

 

[Qaussain]

Expected gt to be 64,

Plane Contains line l, which has. Direction. Vector d1
then Plane was passing through origin, and. there. was Point on Line l
Caluclate d2 by minus it from (0, 0, 0),
Take cross product of d1 and. d2,
normal was (-6, -6, 6) simplifying it (-1, -1, 1) normal.
So The point on Line l and vector product with normal is = d
And d was 0
so eq plane was -x-y+z=0.

Differential equations question? What does mass of B approach?

 

[Qaussain]

Differential equations question? What does mass of B approach?

I guess
B WAS 100/ e square

 

[ALevel2017KID]

I guess
B WAS 100/ e square

Well, got the same here, not sure if its correct tho

 

[Sid200799]

What abt mass of A?
and reflection of A??

 

[ALevel2017KID]

What abt mass of A?
and reflection of A??

I'm super unsure of mass of A, I wrote it approaches zero

 

[Sid200799]

I'm super unsure of mass of A, I wrote it approaches zero

Same

 

[Irfanhaider0533]

Both of the masses were approaching 0

for those who haven't seen it yet heres the maths p3 paper with solutions

[Roselyn Butshe Dube]

The paper was hard, A should be from 57/75

Expected gt to be 64,

how do you know this?
