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?
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?

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

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

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