Edexcel C2 20th May 2015 *Official Thread*

so lets say the official c2 paper has been leaked, will we sit the regional instead?

would your answers still get marked in the edexcel maths exam even if you forgot to label the answers?

For part c) you could just try integrating 1/2 - 1/2cos2x between pi/3 and 0 and that should give you an idea whether your answer is correct or not

We have to know all the volume and surface area formulas for each shape right?

Yes.

No, all examiners have replacement papers written and ready to be printed and used if there's a problem.

Geometric series question


How do we know when to use n or n-1


Thank you!!

Hi, I was wondering in the Trapezium Rule questions, when we find the estimated area, and we get e.g. '0.3175' but the mark scheme have rounded it up to 'awrt 0.32' do we still get all the marks? They haven't stated to round up the answer in the actual question.

Awrt means answer which rounds to

n-1 is when working out nth term e.g. the 6th or 9th term

n is when working out the sum of a geometric series e.g. total of first 10 terms

so would you still get all the marks?

Yes you should. I would write out the full answer then write out a answer to 3sf.

Thanks but sometimes they don't use the forumla
Check the specimen paper, and do the geometric question
See what I mean?
