i lol'd nothing wrong with the method. he should get the marks

was it a definite integral? you need integration by parts to do this (4 unit), but if it's definite, then you can draw a graph and calculate the integral indirectly (method may come up in 3 unit?)

kurt, that would be a lot less messy if you made it d1 = 5 - d2 ..

the textbook gives a lead in, and then it becomes a usual slicing question but with r and h instead of x and y. I think that type of question probably could be tested, as it doesn't really require any extra knowledge.

it's base 2 jks it's actually base 23. however i am using a number system other than decimal

how about: let y = cosx + isinx a)show that dy/dx = iy b)hence show that y = e^ix does this make the same sort of assumption?

yeah, just use a counterexample

Congratulations! According to one theory of personal identity, you have survived! cool

err the description of the volume sounds like a stretched out sphere to me, so i would think that one pi is correct. azereus only left out pi on the one line, it was back at the end

I don't think it would be a trick

if\ x=\alpha\ is\ a\ root\\ 3\alpha ^3 - 2\alpha ^2 + 1 = 0\\ for\ equation\ with\ roots\ x=2\alpha,\ so\ \alpha =x/2\\ 3(x/2)^3 - 2(x/2)^2 + 1 = 0\\

should this be lnL=lim(y>0+) yln[cosh(3/y)] ?

dx, not d日 日is a constant not sure if there should be that 2 in the RHS of the question

if you put \\ at the end of a line it goes to a new line

"2. Find the derivative of ln (1/(2x - 3))" this one can be simplified using log law "3. Differentiate 2^x" use eln[a] = a "I've got everything clear up to integrating e^u" err you should know how to integrate an exponential "7) If P = 100e^(0.5t), find the value of P to the nearest unit if t...

Re: maths question let x=a+3 f(x) = a+ 5 = (a+3)+2 = x+2

i never did westpac :( i want to do it

ICAS I would assume. 40 mostly easy questions in an hour or so

i never learnt it. for polynomials i always just used that method mill showed
