    Yeah i think i got that also
    wasn't the equation y-π/9=-2/3(x-π/6) ???
    i think that gives T: 2x+3y-2π/3=0
    did i get it wrong?

    So I'm pretty sure I got somewhere in the region of 68-71... Could anyone guess whether or not this may be an A*? It would probably be borderline... I really badly messed up the last question but I worked it all the way through and will get error carried forward for part b).

    71 raw marks was the boundary for 100% for the last four years, my teacher told me, so hopefully things dont change and you get over 90%

    Thanks, I very much hope this is the case! I'm pretty sure my mark will be closer to 68 or 69 but if 71 is still about 100 I'll still be in with a chance

    btw Arsey in ur solution the last q abt volume is wrong
    bcz volume = pi * interal of y*2
    not 2pi
    of course, no idea why I did that. I didn't have time to check these answers.

    I don't know what you mean about 3c

    seemed a pretty standard paper to me. I would guess 58-59 / 75
