I got the same x coordinate, but when I tried to get y I got an equation that didn't look like it could be one term if I use exact form. But I am fairly confident that this is the x coordinate of the stationary point.

Dont need to find y

My UOMS as follows;
Question 1: 3-2i
Question 2: 74.2 degrees
Question 3:
Question 4: 16x^3 -24x^2+6x+5
Question 6: , max value was root2/2, Area was 1/4
Question 7: 1/4ln5
Question 8: proof
Question 9: pi*2root3/9
Question 10: intersection at (13/5,1,9/5) distance between parallel lines was 0.488
Question 11: 1+root7i/2, 1-root7i/2, 3i, -3i
Question 13: 1/2ln4+root15
Question 16: 2+ln27, pi(4+3ln25/9)
Sorry dont know if i got all the question numbers correct.

I think Q3 was $\displaystyle \sum_{r=1}^{n} r(r+2) = \frac{1}{6}n(n+1)(2n+7)$

nah there’s absolutely no way, i got basically full marks on all the past papers when assessed in college and there’s no way i’m getting over 100 on this one
