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

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

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

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?
