Oh, I thought you didn't do any Maths at all.. In that case, it may be more viable for you to pickup Ext 1 Maths now and try to catch up with everything, these holidays may be a start. How do you rank in 2U?

Well a tutor helps, but isn't really necessary. EDIT: I just saw that you posted your marks. With those marks you should be fine for 4U. You need to do constant study though, to do well in 4U.

Hmm, did you know that you were going to pursue engineering when you dropped Maths in Year 10? What engineering course specifically do you want to do? Most engineering courses are very mathematically orientated. If you haven't done Maths for 2 years then you will find Ext 1 Maths *VERY*...

What subjects do you do, and what are your 3U marks like?

Ugh... There is a saying - "Two wrongs don't make a right"... [although "three rights make a left" :P]

This is like 4U Mechanics. I think it was in the old course. My old Physics teacher was so hopeless that, he suggested using actual rulers protractors to draw/measure these vector force diagrams. He didn't have a clue of the sine/cosine rule :P

I wish one of my parents was a maths teacher :(

Which EX is it from Math in Focus? I'll try to have a look for you..

Hahaha, I remember doing that one early this year. I wouldn't worry about it though, nothing like that came up in my exams for prelim.

That's because they haven't. Even if we did get this question, it's simple logic - The spaceshuttle would need to be launched near the equator. The Earth's velocity through space is added to the spaceship, thus reducing energy (fuel) required to launch it. But most importantly, we wont be...

That is actually the syllabus dot point, so I think it is correct. They ask identify because they'll only give a multiple choice or a 1 mark question in the HSC for that.

Since I can't be bothered to research that first thing to you, I'll help you with the easiest part. The question is asking you to IDENTIFY... so: A slingshot effect can be provided by planets for space probes. Simple. For that other bit, it should be easy to research.

lol, I don't think Fitzpatrick or Cambridge alone will be enough for 4U. Although, one of the 4U teachers at my school uses those two books and she is a very good teacher.

lol why? You've already completed your HSC...

integral values of n. 'integral' is an adjective ;)

Lets not turn this into an advertisement thread please :) If I wanted to find a tutor here, I'd have posted in the appropriate forums. I wouldn't say that she doesn't know anything about the syllabus... Last time I looked it just comprises of grammar forms that you are expected to know. It...

Probably determining the theoretical values of projectile motion with actual (practical) values. This is what Galileo basically did to predict projectile motion. Perhaps you should ask your teacher for more details, instead of panicking?

Hi, I have problems with the following questions. Could you please show me how to do this, rather than just giving me the answer? Find and plot on complex plane (I can plot myself :P) 1. z4+1=0 2. z2=i 3. z4+16=0 I tried doing these by making them into rcisθ, but I didn't get the...

Hi, In a Galvanic/Voltaic cells, how do I know which metal gets oxidised or reduced, ie. which one is the anode/cathode? Thanks, Jason

1. There is an entry 'corridor' because if the angle is too steep, then the spacecraft will burn up, and if it is too shallow, then the spacecraft will 'skim' back into space. 2. Astronauts feel weightless because they are in free fall, ie there is no reaction force acting upon them.
