I got a squared ln 2 function in my answer, so I think i ****ed that one up :frown:

I had a 32(ln2)^2 in there

Thats my A* ****ed :frown:

hopefully get the one method mark for doing the dividing correctly.
Can you remember what the second part of the question was?

Get Cartesian equation in format x^2+ax+b/x-3
And a is 2 b is -5

Did anyone get 27/32 for the gradient with parametric?

Yep.

God. There is hope yet if so.

I know! I'm not sure if it's right... but maybe we've picked up a few method marks? I hope so

Lol same just glad I wasn't the only one.
I eventually concluded that there was a mistake in the paper and moved on, it's not exactly unheard of haha. Only a 3-marker though :smile:

Haha yeah thanksfully, I thought you had to find another value using cast, but anyway, hopefully we'll get a method mark as compensation. :biggrin:

That last question was a bit of an annoyance. Got 13pi/ln3. Other than that paper was standard. What did others think?

I got the same :smile:

it was harder than usual in my opinion, the Cartesian equation from the parametrics was tricky, and on the DE question for part c) I didn't realise it was in thousands so couldn't do it! Question 8 was certainly tricky. Comparing my answers with people on here, so far so good, which is a massive relief because on C4 I never know if I've got things right or not!

I thought it was an average paper not too hard not too easy. The algebra was a bit messy at times though especially on the last one with x=2ln3-1/ln3 lol

K=4 because when you brought the 2cosø (from changing to dø) inside the root it became 4cos^2ø and it was multiplied by 4cos^2ø to give you 16cos^4ø which when rooted gives you 4cos^2ø so k=4
