This was all the questions:

1) Prove by induction: (8 marks)
2+5+8+...+(3n-1)=(n/2)(3n+1)

2) Sketch showing all important features (32 marks)
a) y=x^3-3x-4 (12 marks)

b)y=[(x^2+x+4)/x] (20 marks)

and we got over an hour

Your math department's got problems...

i agree.

One of the questions for my exam was:
prove:
(1^5 + 2^5 + 3^5 +..+ n^5) + (1^7 + 2^7 + 3^7 +...+ n^7) = 2(n/2(1+2+3+..+n))^4

which is supposedly more 4u induction than 3u induction. This question was worth 6 marks out of the total of 70. Only. But then, once you start it, it just solves itself. You just hafta know how to start.

I agree, that exam was a joke

I know, the rest of my maths class is a joke, Im the only one who got near perfect results. Normally we get harder tests, I was really surprised at this one though.
