[laa.musique]

the link wont work for me

 

[hon1hon2hon3]

My bad, but i actually mean questin 3. . . In his answer , he didnt show theres an induction question 3(b) . . .

The question is

1 x 3 + 2 x 4 + 3 x 5 + . . . + n(n +2) = n/6 ( n+1) (2n +7)

 

[tau281290]

It seems like Board of studies printed 2 different versions of the paper. Ones with induction, and ones without. OMG

Free marks for eveyone?

thats what i had
i got it too (one of the only things i got right)

 

[bendha]

i got the induction question .. that was piss easy

 

[hollyy.]

i got the induction question .. that was piss easy

well la di da. it was the first induction q i have ever gotten right in an exam. i usually get half way through step 3 then give up.

 

[miche11e]

haha yeah me too!! i think he just skipped the induction q by accident. What he has as 3b is actually 3aii.
i do that too - its proof that Terry Lee is infact human!!! :O

 

[I-Love-Jesus]

Grrrrr. I made so many idiotic, imbocilic errors.
I was thinking I had a chance of getting 81. I thought mayb 2 marks worth of stupid maistakes, so 79, that would've been nice. But now that I've seen the solutions, I'm horrified! I lost 3 marks because I ran out of time, and another 11 because of silly mistakes! I thought I was going to get 49/50 Oh well...

 

[Yamiyo]

ALSO HIS QUESTION 5's graph is wrong ? when X = 2 . . y =0 . . his graph dosent show that ?

It says in the question that the domain is x<=1



Is the answer to 1d actually 12C8x2^8x3^4 or am I just incredibly stupid?
