That's what I am getting too: 1.194 cm/s.question asks for rate of change of water level means height..my ans is 1.19 but the book says 4.77
What book is this question in? The answer may be wrong.

http://www.xtremepapers.com/papers/...d AS Level/Mathematics (9709)/9709_y12_sy.pdfcan anybody give me the link to download 'list of formulae(mf9) ?? please !
Yes!thanks a lot.
so all these will be provided to us during the exam ??

please help
june 2006 p3 q 7 (iii)
Would you know if the answers in the book are normally reliable? Because I used two ways to find the answer and both ways gave me the same answer.http://books.google.com.pk/books?id=e3XhP_-1B_UC&pg=PA309&lpg=PA309&dq="Ap is double the 5th"&source=bl&ots=0YUs7HmhMk&sig=TiooH63EveQyfMux7VTZkdsRgJk&hl=en&ei=UJ_fTrWFI4bCswb5wPCJCQ&sa=X&oi=book_result&ct=result&resnum=1&ved=0CBkQ6AEwAA#v=onepage&q="Ap is double the 5th"&f=false
it doesnt show some pages coz its preview
Hello can anyone help me with this?
Question no 3(ii) and question no 8(ii)

Ahh!!! sweeet!! Thanks manQ8(ii):
First of all, we'll draw an argand diagram representing the inequality 'arg(z − u) = (pi)/4'. Next, we'll draw a perpendicular bisector starting from the origin to the line of angle so that it cuts the line of angle at 90°. This is how the diagram will look like (the red lines represent this part of the question)
View attachment 6552
The perpendicular bisector is actually he least value of |z| and this is what we have to find out. Having created a right angle triangle, we can find out the value of this perpendicular bisector using the pythagoras theorem.
3^2 = x^2 + x^2
9 = 2x^2
4.5 = x^2
2.12=x
Therefore, the least value of |z| is 2.12.
p1 question from november 2011 varient 1.. : A curve has equation y=3x^2-6x^2+4x+2 . Show that the gradient of the curve is never negativc .................................. How do u do this , i get the differentiation part but what after that , how do u prove its never negative :S ?
yea maybe the book is wrong..Would you know if the answers in the book are normally reliable? Because I used two ways to find the answer and both ways gave me the same answer.
The first way is obviously using chain rule. The second way is by the following formula:
Rate of flow of liquid = velocity at which liquid is travelling x cross-sectional area of container through which it is flowing.
This also gives the same answer.
So unless we're missing something, it is likely that 4.77 is not the answer.
It's easy convert it into the general formf(x) = 2x^2 -8x + 10 ..... Find an expression for F^-1(x) ....
