What did everyone get for the volume question
9pi^2/4 - pi

almost positive thats right!
4. Got something like V= pi(9/8pi +1) units^3 for my answer to Q7.
5. Thought the paper was harder than usual tbh but these are the answers I got
1. 2ln(x)-3ln(2-x)+c
2i. root 26
ii. r=(1,3,5) + λ(-3,4,-1)
iii. No as λ is not constant
3. pi/4, pi/2, 3pi/4 [+- for all of them].
4i. 5/(2x+4)
ii. (5/x)-1 Domain: x does not equal 0.
iii. graph of the right hand side of an x^2 curve.
iv(a). hg(x)
iv(b). h^-1f(x)
iv(c). gg(x)
5i. Prove Differentiation.
ii. Stationary point at (-2,-1) and it is a max with the value of d2y/dx2=-1/2
6. Proving trig identity.
7. volume= (9π^2/8)+π
8.(1/2)e^2y=(1/2)x^2ln(x)-(1/4)x^2+(1/4)(2e^4+1)
