1. Make tanT for the first equation the subject. 2. Make secT for the second equation the subject. 3. Sub into 1 + tan^2 T = sec^2 T To turn parametric equations into a cartesian equation, you always need to eliminate the parameters. This can be done by simply subbing, where it's something...

Magnetic field is the noun. - There is a magnetic field around the coil. Magnetic field strength is used to describe the intensity (how strong) of the magnetic field. It is a vector as well (it has a direction). - The magnetic field strength around the coil is "2.0 T up the page". Other than...

Yeah, think about it. 3U isn't much of a step from 2U. It isn't like 3U to 4U where the topics are different. For everyone who voted electrical engineering, may I just ask what is captivating about it? Really want to know as I never thought of it as an option for myself. It may be because I...

Read your other thread that you made that says the exact same thing. http://community.boredofstudies.org/showthread.php?t=316022

True. In fact, you will gain. After you see the 3u stuff, you would view the 2u questions as easy. Next year will still only be preliminaries for you, that's the time to experiment.

Electrical is really popular, isn't it? With all the chemical engineering threads, I would have thought chemical engineering was more popular.

If you did do 3U maths and physics, which engineering course would you have chosen? Are you pursuing a research career?

Tossing between BE (Chemical) and BE (bioinformatics).

I could only fit 10 options in the poll. If the one you're applying for isn't there, feel free to post it below. Guests can vote as well. EDIT: Multiple options are allowed. EDIT: Silly me, I forgot "you" in the thread title.

Can I just tell you to be cautious when choosing more than 1 subject you're bad at? I know many people who chose 2 subjects they thought was a good idea and ended up having to deal with one of them since they could only drop 1 of the subjects in year 12. This is unless, your school has some...

Sorry to bring this thread back alive. However, I want to clarify just to prevent any further confusion to future readers. 1. Yes, you do round your answer off to the LEAST SIGNIFICANT FIGURE in the question. For official HSC question, the values in the question "usually" have the same...

Personally, I have tried studying ahead in the holidays and it doesn't work for me. Physics in year 11 and year 12 is harder to understand than the physics in junior science. You will notice that it would require a lot of "visualising". But studying ahead might work for you, if you're like...

Very important point to consider. You still have the entire preliminary course to make up your mind. I would stick with 2U. If you pick general you would may/may not regret not trying 2U. However, if you pick 2U you definitely won't regret it. You can always drop. That way, you won't regret it...

1. Find out how many students (in each year) in your school in the previous years received band 6. You can do this by using the High Achiever's Database found in the Cohort ATAR thread. Or, you can use this site where it tells. I'm not sure what the site is though, hopefully someone reading this...

I guess my notes lived a boring life.

Personally, I would use your time more wisely than making up an exam. However, it's your choice. May I suggest buying Phoenix Past Paper Book? It's ideal for situations like these. It's a book with past paper questions. Unlike success one, it actually sorted the questions topic by topic...

I second that. For topic tests/early assessments where there are only specific topics in the test, I would the phoenix books. It's easier than the success ones as it's actually sorted by topic (not with an index like success one). OP, if I was in your situation, what I would do is just...

This break is a good time to finish your creative writing for English. You'll need it for AT LEAST your half yearly, yearly and HSC exam. Many of the people at my school were stressing over what to write for their creative writing a week before half yearly. They had to come up with a creative...

Here's my input. On the official UNSW Chemical Engineering website, it says its course is 1st in Australia and 6th in the World. Of course, the organisation ranking the universities is different to the ones anomalousdecay posted. This is the link...

This guy is spot on. Doing high school physics with a 2 unit mathematics background is more than enough. Even with just preliminary 2 unit mathematics, you can breeze through the 'mathematics' with ease. I placed mathematics in quotation marks because I really mean, mathematics mathematics...
