Do you mean divide x^3 by 2-x^2, as in polynomial division? EDIT: never mind I got it thanks for the help.

Damn, this is a 3 unit question (I think harder 2 unit), I dont know partial fractions...It was in a 3 unit exam.

Hi everyone: Quick Question: How do you integrate x^3/(2-x^2) ?

Why do you have two identical threads? I replied in the other thread (the original one): http://www.boredofstudies.org/community/showthread.php?t=67577

Yep its a great idea..and as Rench said its better that the questions are completely unknown to us and not from one of the commonly available text books.

The describe essay (the first one) should be bout 500 or 600 words max - basically two - two and a half pages A4 at most. You should be able to write it in about 15 minutes..The assess one should be longer and about 800 words or so, so thats about 3 and a half pages perhaps a bit less...you...

Thanks :)

Parabola Question I can't get. H (2ah, -ah^2) and Q (2aq, -aq^2) are two variable points on the parabola x^2=-4ay Let the point of intersection of HQ with the y axis be the fixed point T (0, -3a) where a>0. The normals to the parabola at the points H and Q meet at the point K. Assume that...

There's plenty of info on Speer available. Tell us what you need help with specifically or if you dont understand a particular section...

Ok firstly it says account for, so basically its asking for reasons why democratic forces were unable to counter the nazis. There are a number of schools of thought. You could say that the Nazi party was very strong and had the support of the population (which is ok but not completely true IMO...

17. You do this one by first rearranging the equation of the circle: x^2 - 8x +y^2 +4y -5=0 complete the square for both x^2 and y^2 [x-4]^2 -16 + [y+2]^2 -5=5 [x-4]^2 + [y+2]^2=25 so you have a circle with centre (4, -2) and radius 5. To prove its tangent use the perpendicular distance...

Perhaps your right, the answers say 236 but I am getting 259 as well.

arc means the inverse function like arcsin is sin^-1 its just to differentiate it from cosec

(a) sin2@/4 = sin@/3 6sin@cos@=4sin@ divide by sin@ 6cos@=4 therefore cos@=4/6=2/3 where alpha is angle C (b) sin3@/4=sin@/3 Remember that sin3@ = 3sin@-4sin^3@ so 9sin@-4sin^3@=4sin@ sin@(9-4sin^2@)=4sin@ divide by sin@ so 9-4sin^2@=4 sin^2@=5/12 so sin@=sqrt5/sqrt12 rationalise...

Question 9 (a) in James Ruse 1993 2 unit paper trial HSC paper: The area in the first quadrant, under the curve y = xe^x, the line x=2 and the x-axis is rotated about the x axis. (i) Write down a definite integral which gives the volume of the generated solid (ii) Calculate an estimate...

Im sure they could ask it. There are some in the Fitzpatrik 2 unit book...I remember a question on volumes using simspons rule, someone posted it up a few weeks back I think.

nope fully public and non-selective.

Nah, I did modern history as an accelerated course... so i did it in year 10 and 11 :)

lol I did modern history last year and got 94 :) Im doing too many units to do extension this year hehe

Yeah. On one side he denies any knowledge so you talk about that and on the other he was ready to do all that was possible to prolong the war...even though he knew it was over by 1943. some historians such as Dan van der vat argue that Speer exaggerated the statistics on his own performance...
