The inequality in 11e) is only > than, not >=, isn't it?

q11e should be strict inequality

edit: somebody already corrected this

11.f should be +1 not -1

edit: the product rule at the start is wrong is all, error carried through

11 f) the derivative of e^x lnx should have a + sign, not a - sign

Haha cheers for all this! My goodness, such trivial errors.

It appears that I can neither read nor use the product rule!

Had a quick look through, could only spot the product rule error.

other than that everything looks good i think.
would i lose a mark for not writing the units in 12a)ii) ?
and in part 13ciii (parametrics), i only stated that y =/= 2a, i didn't say x =/= 0. would i lose a mark for this?
