Yay, I got my results back today Here they go: English - 93 Mathematics - 96 Science - 99 Aust Geo - 91 Aust His - 92 Computing Skills - 95 Congratz on everyone else for all of their wonderful results and efforts!!

hey man, what school do you go to? im just curious... those are excellent marks btw!!!! :drink: congratz again, lookoutastroboy

Hey guys, I really need help with these superannuation/series questions. They're of Yr 11/12 advanced standard. Q1. An amount of $3000 is invested in a superannuation fund at the start of each year for 18 years. The interest at a rate of 9% p.a is paid every half-year. How much is the...

lol thanks for everyone's responses - i really appreciated the help and effort just one more question - when you do maximum/minimum turning point questions, my teacher said to try in the derivatives for x on either side of a stationary point x. I did this for the question below, as...

no answer

the answer seems to be 2 divided by sqrt 2x but i have got the right answer but cannot seem to simplify it to be that answer, any tips? thanks for the help both of you, lookoutastroboy

Hey guys, Got stuck on another question that has 2 answers - very weird... hope someone can see the flaw in it somewhere Anyway, the question was to find the stationary points on the curve y = x squared - x cubed. The two points were found to be (0,) and (2/3, 4/27) i put: when x...

thanks everyone for helping me solve the problem. I guess factorisation can be a bit tricky when it involves a lot of terms good work especially to annabackwards and timothy siu just one small extra query if possible - does using different ways of differentiating an expression always...

Thanks Timothy for the reply, the answer is 1/(x squared + 1) to the power of 3/2 can you somehow derive that answer? thanks again, lookoutastroboy

Hey guys, I'm having trouble on differentiating this expression (its easy but I cannot seem to factorise it properly - may not be doing it right anyway: the expression is x/sqrt (x squared + 1) If someone could show me step-by-step how to do it, it'd be greatly appreciated...

Hey guys, I am currently working on a VB6 (Enterprise Edition) project and have based my project on a fast food campaign. However, I wanted to know if there was any way of importing a video/s into a form. For example, how would you import a video from this link about KFC: KFC Australia -...
