That was a different question.

 

[underthesun]

Hmm, either I forgot or did not attempt. Can someone confirm?

that was easy

sin^2A -2sinAcosA + cos^2 A

= 1 - sin 2A

 

[underthesun]

no I mean integrate sin^2 x, was there such question?

Maybe our school supplemented that question or something?

 

[SoCal]

By the way Underthesun, that was sin^2 3x not sin^2 x.

Can someone please confirm?

I think it was this question, which they are referring to.

Edit underthesun beat me to it

what qns number was that

 

[Lord Ac]

I got h = 8.06!

yay! cause there was no 3D trig. in the last couple years and I hadnt practised!! But i got it. nice big diagrams!

I think people tend to remember questions specifically rather than question numbers.

"Hey guys, did anyone get 6(c) part (iii)?"
or
"Hey guys, how did you find that binomial probability dice question? It was a tough one hey?" (this is used to highlight my point, it may or may not be verisimilitude (there's Frontline at work))

 

[yeahyeahyeahs]

omg i wanted to CRY!

i couldnt do half of the Qs, I did so many practice papers and past papers (well not that much but quite substantial) and they were NOWHERE near as hard as this. glad to know the answer is 8m i got that! so thats what 4/80 marks woohoo

 

[m3h_m3h]

that was a pretty hard test. i was killinQ.1-4. then i looked and 5,6,7 and felt like just laffing out extrememly loud.

Did you?

So.. did anyone see (sin^2 (3x)) integration question?

oh no! did I miss a question?
AHHHHHHH 4 MARKS GONE AHHH
runs away in dismay

My feelings exactly.
Don't remember seeing a (sin^2 (3x)) integration question either
