Thanks. That's an interesting way to look at the question. Definitely more structured than a table of values :lol: thanks!

2U ezpz I'd say stay. But on the other hand, 24% is worrying. Considering that two people passed, there is quite a large gap between the top kids and the rest.

Hello, "Sketch the graph of y= |x+1| - |1-x|" From what I know, to solve is to use the ++ , +-, -+ and -- method, and somehow, the result becomes what seems to be a piecemeal function. Any help please? thanks.

o wat.. font finders exist! my life is complete.

Yo guys, do you know what font they use for the cambridge mathematics books? It's so aesthetically pleasing...

$40 for one-on-one is quite a decent rate actually. High achievers who don't have tutors are usually highly motivated, productive workers. If you can handle extra work loads to cut down procrastination, then tutoring could benefit you.

Yes plz

The question is to prove "The angle in a semi-circle is a right angle". Initially, I thought of the locus of a circle, with x-coordinate being acos(theta) and the y-coordinate being asin(theta) (for convenience, theta will be z) so x = acosz and y = asinz and cosz = x/a and sinz = y/a By using...

Just finished my prelim exam, and I have two main questions If there is a charged plate, with charges X,Y, and Z residing within it. All the charges are equal. X,Y, and Z are located at different positions within the plate. X is closer to the positive side, Z in the middle and Y closer to the...

4U gonna catch me with my pants down just like 3U did at the start of year 11. It was traumatising :(

Might be a bit late to say this, but good luck to all my fellow prelim students who are currently doing their final exams! Can't wait for holidays to start so I can start fresh again and study more efficiently

From what I know, different websites use different algorithms/take different things into account. For example, "better education" offers three different ranking methods, with one based on "alumni who received the top order of Australia honours". You will notice that other websites such as Matrix...

I call bs. White on the outside, asian at heart.

Very impressive.

Hi, I will ask my teacher and see what papers I can get my hands on. Care to trade somehow?

Yeah and they're quite challenging too

Hey! Looking for any independent prelim papers for EXT 1:cook: Please PM me if you're willing to share!

GG no re

woah man, super impressive

Yes, I definately took that into account, but how would that be expressed? sin8x = 2(sin4xcos4x) = 2((2sin2xcos2x)(2cos^2x-2sin^2x))...
