All i remember was when I put that 7 marker for integration into my calculator it took 20 years to churn out the answer.

thought mine was going to set on fire at one point.. I had to do it twice as well as I thought I messed it up oh dear oh dear

Here's my (half complete) unofficial mark scheme with worked solutions

Think they're all right, have checked with desmos/wolfram

Couldn't remember some questions or the questions numbers!

The answer to Q9 is wrong somewhere, -21.3 degrees is the only actual right answer but idk why

at the maxium point of the graph, the gradient is 0. So differentiate 16x-e^(2x) and equate it to 0. 16-2e^2x=0 so 16=2e^2x so 8=e^2x so sqrt(8)=e^x. ln(sqrt(8))=x which is the same as 0.5ln(8). so f(x) is less than or equal to 0.5ln(8). I got 0/5 in that question probably but as soon as I got out the of exam, I realised the gradient is 0 and solved it in my head! So annoyed with myself.

You had to also substitute 0.5ln8 into f(x), as the range is f(x)<= the Y coordinate. I got 8-8ln(8) or something like that.

For those asking about Q9
i) We know secx +tan x = -5 and sec^2x -tan^2x = 1 (as an identity) factorising the identity gives (secx+tanx)(secx-tanx)=1 and by substituing in the first equality we find secx-tanx=-0.2
ii) add secx+tanx = -5 and secx-tanx=-.02 to get 2secx = -5.2
secx=-2.6
cosx=-5/13
iii) let theta equal the old x
2x-70=theta
2x-70=+-arcos(5/13) + 360n
Rearrange for x and you get two answers (-23.somethinng and almost -90 can't remember exactly)
You substitute them back in to the original equation to check, the -23.something one works and the other doesn't, leaving the -23.something as the only solution
