1. (Original post by Ayaz789)
(e^1 * pi/5 ) + answer in part 1
Thanks!
2. Question 2 b?
3. Guys any idea whats gonna be an A* this year?🙈

(e^1 * pi/5 ) + answer in part 1
I got e^1 * answer in part 1 because you could just take out th e^1 from the integral.

Are you sure ? i thought it was e^1* answer of part a

Probably 63-64
7. What did people get for the domain of f-1(x)?
I think I put [9,infinity)
8. I agree. Used the same method

I agree

Yeah i got that

But you have to times by pi/5 , ive seen it in past papers
Check summer 2012, it is the same

He's right because is was exponential, if it wasn't then times by pi/5 would've been correct but all you had do to was times part a by e^1

my method was to just type in the integral :e^ 1/cos(x)^2 into my calculator with the boundaries pi/5 and 0

I cant remember what I did then but that was my method
14. We should all be fine then 😄 Fingers crossed

No, u only time by pi/5, if you had to the find the integral of (something something + e^1) but you had to find the integral of (something something * e^1) so u can just pull e^1 out of the whole integral.
Something something indicates the equation we had to integrate in the first part, but I can't remember what we had to integrate exactly sorry!
16. What about the parametric differentiation q where you had to give the second derivative in terms of y?

So am i right?
No it's just times by e^1

I silll am quite sure im right :/
20. a and b values for transformations?
