Maths AQA C1 revision - 14th January 2013

Oh yeah I think I did simplify the -9 + 11 to +2. You did get -9 +11 before you changed it to +2, right?

I think the surd question was:

7root2-root3 divided by 2root2-root3

multiplying by 2root2+root3 should have given you the answer 5+root6 after simplifying.

So have we concluded that for the translation one the answer was

[-3]
-2

with the word 'translation'?

yepyepyep

What did everyone get for the length of PQ, or was it CQ? The one where you could have used Pythagoras. I got 9, but i think i may have forgotten to square root it and out 3, i think i may have just left it as 9- not sure LOL

Unofficial mark scheme anyone? I think we've got the general gist of all the questions. Which ones are we missing?

Do you remember the one before that?

what did people get for the length of CP? and the length of the tangent of PQ or something??

wasn't the length of CP root34

at least i remember that was one of my answers for something

wasn't the length of CP root34

at least i remember that was one of my answers for something

dammit, i put positive 3 and positive 2 haha

it was 3 over 2 translation because the equation before was (x-3)^2+2
