How did you get the area of the stupid triangle!!

Basic igcse formula, umm 1/2 a^2 sin(x)

OMG !!! I was going about getting theta/2 so stupifd

)) Did i just shatter all your hopes
How much do u expect you'll get?

 

[amina1300]

What was the normal vector?

I forgot most of my answers

I guess around 65 66 I missed random parts of questions here and there bec of time.

 

[amina1300]

WBU ? Prolly around 70 ??? .

I need an A* so baad, just wishing the threshold to be 60...

Ah Insha'Allah, I think 72

 

[amina1300]

How much do you need overall for an A?

 

[kochiboy69]

180+

what did you all do for the skewed lines bit in vectors

 

[Mts.99]

was there a 13/36 term in binomial expansion?

Equate them together and then get the S and U and then substitute in the third eq and u should have got 7=-7 which werent equal

nop, i think so.
It had x x^2 and x^3

 

[Zaki ali asghar]

there was no constant in binomial, i don't remember the other terms but x^3 was -31/108

 

[xoxoxoxo123276]

Does anyone have the solved 2018 p12 ?

 

[~mxlihxh]

there was no constant in binomial, i don't remember the other terms but x^3 was -31/108

I think this is what I got, too

YASS thats what i did i had no idea what the question meant tbh

 

[Somaiyah]

What were the stationary points?

 

[Zaki ali asghar]

(3^1/3,0) don't remember the other one.
