then you would use the chain rule like nightweaver066 did

$We want to manipulate our expression so it is in the form $y=\sin^{-1} \left( \frac{x-b}{a}\right )$ if we want to use that formula (the formula still works when you replace $x$ with $x-b$ as long it is a monic linear function):$\\\\\indent y = \sin^{-1} \left( \frac{2x-1}{3}\right...

$From part 1), you found that: $ \frac{d}{dx}\left[(9-x^2)^{\frac{1}{2}} \right ]=-x(9-x^2)^{-\frac{1}{2}}\\\\\indent\indent\indent\indent\indent\indent\indent\indent\indent\indent\indent\indent\indent\indent\:\:=\frac{-x}{(9-x^2)^{\frac{1}{2}} }\\\\$You are trying to find ${\displaystyle}\int...

Apart from practice, I recommend using a pen which you feel most comfortable writing with (e.g. one with a grip). From my experience in HSC, I used a light-weight, inky pen which allowed me to write fluidly which was very helpful. You don't want to use a pen which feels like you are painfully...

Go here: http://sydney.edu.au/library/elearning/learn/plagiarism/index.php and go thru the whole video then when it's finished print the certificate. Shouldn't take long...

OMG SAME HERE! I got the error thing too! D: D: D:

$For the second part:$\\\\$LHS$=(k-1)\sin(A+B)\\\\=(k-1)(sinAcosB+sinBcosA).\\\\$ Ok so if we stop to look at the RHS, you can see that our aim here is to get rid of$ (k-1) $and replace it with $(k+1)$ and somehow change to sin(A-B). This is where we can use $\tan A=k\tan B.$ If you look at our...

$So we are given that $ \tan x=t.$ Usually with these sort of trig problems you will firstly draw a triangle with the trigonometric ratio (you will see how it is useful later): *see attachment* $ \\\\$You can work out the hypotenuse to be $\sqrt{1+t^2}$ using Pythagora's Theorem.\\\\So now we...

fire alarms? O_O why were there fire alarms?

*sigh* feel so bad for not seeing you guys :S

the first time i slept early, woke up and came early for an 8am lecture and they said it was cancelled :( i guess i'll find you before MATH1902 lecture, then i can prob ask my friends to come sit with you guys as well in one row LOL

oh really? dang...where did you sit? are you gonna crash the same lecture tmr? :P

awwww didn't meet you today but i wasn't sure if it was you:/ Were you the guy who wore the blue shirt and sat at the bottom-leftish of the theatre?

Go to Library tab from USYD homepage>databases and electronic resources tab> go to W>find "Web of Knowledge"

Added ;)...Awesome, I'll probably be a little late for the lecture again coz I'm sometimes lazy getting up so early :P but I'll try my best to identify you:D yeh i went to check out the new place in Carslaw today, and you're right it DOES have that new place smell! and pretty cool too :)

LOL this is physics not psych.

haha yeh Carrotsticks told me LOL...uhhh what do you look like? and where do you usually sit? XD ,

I think I read somewhere that you can do tutorial questions in MasteringPhysics and apparently you get assessed for group work you do in tutorials which is 2%.....well you can find this all under the "Assessments" tab in the unit outline on blackboard.

You type in codes in something called LaTex form (you can use the program "Online Latex Equation Editor" to test it out) and different codes correspond to a different symbol. If you want to post it here you put the code between "[ tex ]" and "[ /tex ]" (just without the spaces of course). For...

I think your expansion of the numerator in 2nd fraction from 2nd to 3rd line should be "9Root2+3Root5"
