Mathematics: Post your doubts here!

[Alice123]

I really don't know. I didn't do as well as I was hoping but same was the case with P1 last year. I came out expecting a 'b' but Alhamdulillah I got an 'a'.
So yeah, don't know what to expect CIE can surprise me with the results

What about you?

bt p1 was alot easier... i cud answer everything...bt in today's paper i really dnt knw wht i did in the last part( qs 9 n 10)

Oh it's ok. Everything happens for your good Don't think too much about it. Better to concentrate on the remaining papers. At least that's what I'm gonna do.

Alright! My fellow mathematicians I'm done with Math so I'll be off now.
Nice getting to know you all !

Q4 (ii) can someone explain this please !?
actually i got the answer by doing ( 11!/5! x 4! x 2!) but why do we do this and why not 5P5 x 4P4 x2P2 ) ?

 

[Rutzaba]

oh its because since all the presents are going to be distributed among 11 players so 11! and then dividing the presents 5 pens = 5!, 4 diaries= 4!, 2 notebooks = 2!
so you have 11! / 5! x 4! x 2!
the purpose of factorial ' ! ' is that it works like 11 x 10 x 9 x 8 x .... as the players get the gifts the total number of gifts and the players waiting to recieve the gift decreases..
do you get it?

p32 was good i did all questions and sure of all except complex 1st part

 

[Jiyad Ahsan]

how was it ppl!

awful the last 2 questions were hell !!!
the stupid complex number thing wasnt even printed properly.. it said the Re > 0.. which was supposed to mean that the real part was greater than zero.. WTH !? was i supposed to guess that Re meant real part?

Please don't discuss the questions yet
Just so you know, Re means real part is something you are supposed to know, not guess.
