How did we all go?

[Joseph41]

So - thoughts?

[exoticspice]

it was annoying to say the least 

[accountingpro]

Wasn't that difficult, bit strange though.
Very happy with it though.

[Jackson.Sprigg]

There were so many domain and range questions tf

[Nad_C]

Does anyone know where i could find a copy of the exam? From a concerned maths tutor lmao

[jinaede1342]

Made a few careless errors in the trig question, but overall the exam was very manageable. Definitely easier than 2018 imo

[Sai Ramishetty]

How did u guys find the maximum area question. Did u guys get (8^1/2)/9?

let a = 1/2*(x+1)*sqrt(1-(x^2)) da/dx = 0 at x=1/2 a(1/2) = 3sqrt(3)/8

can’t guarantee that’s right but I think that’s what I got

[Sai Ramishetty]

let a = 1/2*(x+1)*sqrt(1-(x^2)) da/dx = 0 at x=1/2 a(1/2) = 3sqrt(3)/8

I just checked on the cas. Ur answer is correct

[accountingpro]

let a = 1/2*(x+1)*sqrt(1-(x^2)) da/dx = 0 at x=1/2 a(1/2) = 3sqrt(3)/8

Yep. The diff cancelled out well

[ArtyDreams]

yeah I feel like I screwed it up with so many silly mistakes - I felt like I knew what I was doing but made so many algebra errors - thought last years was so much easier. I couldnt even do the diff for the triangle question....

So many domain and range questions - it is literally my weakest point.

Yeppp got the same ans
-Rang n domain qn tripped me upp rippp
Other than that it was pre gucci

[Bhoomija]

Does anyone know what could be the number of solutions for f(g(x)) + g(f(x)) = 0?
