this is the one with the minimum (a,b) and you have to find a and b, did anyone get the same as me?

so a = -0.196

then put x = -0.196 into the original equation to find b = 0.812

graph of y = ln(|x|) was pretty simple, i checked on wolframalpha, got it right
17. Very hard I thought. Here are my solutions (updated!)

19. Piss easy exam, I made a mistake with the cosec^2x - cot2x question because I did it so many times on the Elmwood papers that I rushed this question, I still got 22.5 as one value so it's probably 2 lost marks.

Very hard I thought. Here are my solutions
for question 8 you could change cot2x=0 to cos2x/sin2x=0 and so you have cos2x=0. i did the same as you though

Very hard I thought. Here are my solutions
also for the last question (the range of fg) i got it's >4 because the minimum is already at the point (1,1) before the +3
