heaps of people say that cartoons are good to use as related texts for power play but im having a really hard time finding any...the ones in the SMH are pretty dodgy and don't relate to powerplay, most others i can find (the australian, financial review) are about completely different issues...

yeah my friend is the same...german + italian is at the same time i think? so she gets locked in the room with her lunch after finishing one of them so she cant communicate with anyone until the next one starts. pretty tough situation to be in.

oh ok thats great...thanks a lot!

i have an assessment tomorrow and found this while revising prove that sin^-1x = cosec^-1(1/x) how do you prove that? and there was a similar one that asked you to draw a graph of cotx then use it to obtain a graph of the inverse, then write down a definition of inverse...

yep i agree with what everyone has said about the casio fx-82AU! its sooooo good and the display means you don't have to worry about putting in loads of brackets and you know exactly what you're putting in. it also has the Pol function which puts complex numbers into mod-arg form, plus its...

someone told me ryde was really good and chatswood fails everyone but i don't really know.....i think manly and north sydney are ok though.

I read to relax and calm down before i go to sleep after studying....ive found that now i cant sleep unless i read something. i just read what i find interesting and enjoy, i really liked dan brown's books cuz i like books relating to history, but some of my friends don't read anymore because...

i wasnt sure if you could use integration by parts since it was cos of a function, but thats great thanks.

hey guys, how do you integrate cos(lnx)? i have no idea, thanks.

ok thanks, i forgot about using substitutions.

oh right...that seems so simple now, thanks for your help with that one!

1. The equation x³ + qx + r has roots alpha (a), beta (b) and gamma (c). Find expressions for a) a² + b² + c² b) a⁴ + b⁴ + c⁴ c) a⁵ + b⁵ + c⁵ <o></o> for part a) I just did...

thats great...thanks!

k is 0, 1, 2, 3.... right? then won't you get the solutions just as cis(pi), cis(3pi), cis(5pi) etc? is that right? lol im probably been really dumb here...

from cambridge 4.4: show that the zeroes of P(x)=x⁴-x²+1 are included in the zeroes of x⁶+1. Hence factorise P(x) over R. first part is fine, i factorised it as a cubic. but how do you find roots, not including x=1, x=-1, of x^6+1? since it is an even power...

point p divides a line AB in the ratio of 1:2 where A is a point on the yaxis and B is a point on the x axis. i) show that the locus of P is an ellipse and write its equation. ii) what would the locus of P be if P were midpoint of AB? q from textbook...no answer, thanks for ur help! :)

oh right, i tmakes more sense when i think about it in terms of y=sqrt x^2 instead of all this trig, thanks for your help guys :)

in fitz exercise 30a it asks you to graph y=sqrt ((cosx - 1)²) Can't you simplify this to y=cosx - 1 and graph that? But when I graphed it on my graphing program, I was wrong. I know Im missing something but I'm starting to get really confused about it - could someone clarify this...

thanks that's great. that would explain why i found it so hard, we did trig so long ago and i completely forgot about the t formulas. thanks for your help :)

This question is from the prelim maths in focus book (p272) - studying for half yearly. A cylinder with radius 4cm and perpendicular height 15cm is tilted so that it will just fit inside a 12cm high box. at what angle must it be tilted? Answer 16° 50' i have no idea where to start...
