Why bother with a post grad course - waste of time? 17-10-2016

Why is that simplified? That's factorised
uh why not both? factorisation = simplify. I think.
2. (Original post by Mahrez)
swear it is inversley proportional
oh yh it was sorry, (my bad) that's what i meant and did in exam

It probably confused you as it wasn't put into words 'y is directly proportional...' as they just wrote x (proportional sign thingy) 1/x squared
Yep... why would they do that ffs they put that fuking symbol in

What did you get for the midpoint Q ?

Factorise and expand are opposite processes. Who is to say one is simplified compared to the other? They must accept 100-25pi it does NOT ask to factorise the answer

it will make no difference your table will still be correct if you said it was k/x2 then it will work fine

I can't remember my answer but i believe for that question you do the reverse of you do when you're finding the midpoint, as they were asking for the end point or something. So times the midpoint by 2 and then subtract form the other endpoint.

But why would they say simplify if you didn't actually had to simplify. Are you denying that 25(4-pi) is the simplest form of 100-25pi..?
9. I got an area of 2 for the last question 🤔

I am. The maths term for that is factorise not simplify!

Indeed look at this American version

12. I did the foundation paper. I wonder when Mr M will publish the mark scheme for both higher and foundation. I think I did alright overall. Definitely enough to get into the 70+ marks bracket.
13. convince your school and teachers to get hegarty maths its life saver
14. "A fraction is in simplest form when the top and bottom cannot be any smaller" OKAY NOW, HOW DO YOU GET THIS: (100-25pi)/1 SMALLER PLEASE TELL ME
15. The root 6 became root 36.
My LCM was 2..

My LCM was 2..
The large triangle was 1/2*√2/2*√2/2 = 2/8 = 1/4

The small triangle was 1/2*√3/3*√2/2= √6/12

Large triangle - Small triangle = gray area

1/4 - √6/12 is equivalent to (3 - √6)/12

Edexcel unofficial markscheme - http://www.thestudentroom.co.uk/show....php?t=4120523
I'd be interested in seeing the one for Foundation
18. what did everyone get for the standard form question?
what did everyone get for the standard form question?
7x10^8

I also did foundation and think I did ok would love to see a mark scheme for ours
