Differentiation!

Argh... I know what to do, but now I'm stuck with differentiating this;


16(pi)h^3
81

(see what i did there with underlining and fractions? :-P)

I'm stuck. Quite bad.

Help! :-)

I do further too........

Maths is gaybar.

Most of the stuff you do is also about as useful as having an ass on the back of your head.

who cares a A* or what ever

*explodes*

Its not essential you get an A* I was one of about 5 or so that got A*'s in my year, and only i was recommended to do Further Maths. The other 3 of our massive class only got A's and they are just as able. If you like Maths it'll be a challenge, but it's definitely worth it. But dont feel sorry for yourself when you end up with 10 Maths lessons a week, well thats what I have, which works out to at least one maths lesson a day, and then a day with 4 consecutive hours of Maths :(

Ah, you see, I can't see myself getting anything other than an A.

Which should be simplified to 16/27(pi)h²

You could "simplify" it more, but it's needless.

Did you get A* at GCSE?

A-level Maths is easy, and I do Further. Thats double what all ye A-Level Maths guys are doing. Anyway the syllabus has changed this year, so now its rediculously easy...
