Do you get marked down if you answer in degrees when the intervals are in radians?

They don't explicitly say 'give your answers in degrees/radians' :erm:

Yes you do. If its radians then you answer should be. They dont need to state it to know a accuracy mark off.

I dontknow edexcel, I do ocr but in our papers we will get marked down if our FINAL answer is in degrees when the question talks about radians.

Does anyone have any ideas on what will be on the paper and in what order? Like what will be the hard questions, trig or integration etc. I think you will have to prove the sum of n terms formula as it hasn't appeared in three years.

X=2 is a root. Divide x-2 !

Guys when doing geometric sequences and solving summation questions when do you use:
just "n" as in ar^n
and "n-1" as in ar^n-1

Part a just form an equation to find volume
