Anyone else get a runtime error when trying to apply for travel concession after pre-enrolling online? I pre-enrolled a couple of days ago and got through the pre-enrolment fine, clicked the registration link for travel concession and read through the declaration thing... Went to click "I...

I was just wondering how common it is for a lecturer to change the due date of an assignment. For example: The lecturer gave the assignment out a couple of months before it was due, with the due date written on the sheet. About a month into it, he realised he'd given us 2 extra weeks than he...

Approximately how many pages should a composition diary be? Cheers.

What would the dependent and independent variables be for an experiment measuring the resistance of a motor, or indeed any resistor (where you make a circuit with voltage and ammeter, draw a graph of V vs. I and use the gradient if Ohmic resistor? I can't really apply the what you change and...

I always get this wrong because I get confused between the + or - in: Rsin(x+θ) , Rsin(x-θ) , Rcos(x+θ) , Rcos(x-θ) Here's one example: a) Change y= 3cos(x) - 4sin(x) into the form y=Rcos(x-θ) and sketch. b) hence solve 3sinx - 4cosx = 2 Thanks :)

I really don't get what all the fuss is about. I actually find it infuriating when people are like: "It's the HSC! Worry everybody! This is the most important thing EVER. It's so important and we have to have no lives because all we're going to do is study! Have you started studying yet? Why...

Could someone please give me the theory for this? Just in case it's in the test tomorrow!!! eeek... It's like: but I think (2) might be wrong... Help please. :)

For some reason, I have the greatest difficulty in using a burette. I can rinse with the appropriate solution and fill it accurately, I just can't turn it on/off. The 'rough' run through goes ok, because accuracy isn't the concern, but for real titrations, I'm useless! My results are always...

Apparently there has been a policy making all schools sing the National Anthem (two verses). A CD was issued to schools which had 4 tracks, each being the anthem (one choir, one that sounds like MIDI, and I haven't had the pleasure of hearing the others yet), as well as cards with the lyrics on...

Find the equation of the curve through (-60,18), (0,0) and (40,8) presuming it is in the form y=ax^(2n). Answer is y=x^2/200 I tried to make simultaneous equations, but it didn't seem to work for me. Heh, I'm stuck again.

I have a concept, but no ideas for plot or character. Really it comes down to a decision, but I can't make that decision. Far out! My idea's not even good to start with... at this point everything seems unworkable. Why can't the teachers just tell me what to write? I seriously can't do this...

Just taking the mass dilation effect as an example... Near the speed of light the object (from a moving frame of reference) will have a real increase in mass, but when it becomes stationary again, it returns to 'normal' mass. Correct? So where does the mass go? I know where it comes from...

I know I should have started this already, but I haven't. I don't know how to begin. Seems like such an ominous task. The first word of the journal... how can I start it? We did writing tasks given to us by the teacher first, but so what? To me it feels like it needs an intro before launching...

How do people just come up with ideas for their major works? My teacher thinks that a critical response would be the best option for me, but I am yet to think of anything that sounds even remotely like the beginning of a thought process that could lead to an idea. The rest of my class - "I'm...

I've been attempting to prove that 45 degrees is the angle required for maximum range of a projectile, but have been unsuccessful in finding the equation that will allow me to differentiate... It sounded quite simple when I started trying, then an hour later it was still no luck. If I was to...

Wow. I really can't picture myself as a HSC student. Anyone else think that they're so ridiculously immature to begin such an important part of life? Or is that just me? I mean, this is IT! The HSC we're starting here. Those three horrendous letters... already getting to me... ahhhh! Already I...
