    Mathematics for engineering

    Hi there, I definitely want to do engineering in university but I see that most assumed knowledge is math extension 1. The issue is that I'm currently doing general math and I'm wondering how essential this is and whether it is super necessary to take on a bridging course or not.

    If it helps, I'm doing great at engineering, physics and general math!

    Re: Mathematics for engineering

    My engineering studies teacher's daughter does Civil engineering at UTS and she used to get 90's in General. In uni, she get's low 50's in math exams. That's just an example though, you can always do the summer school where they teach you what you will need to know before uni starts, or you can learn it yourself with some dedication, summer school is intensive and expensive but may be worth looking into. But generally, engineering 1st year is about 4u math equivalent, it just increases as you progress , but it depends on your major as well. Just remember that getting into uni is the hard part, once your in, you will have help available. Study now to get the best ATAR since Math extension 1 is only "ASSUMED" not a prerequisite.

    general maths?

    Really?


    why the hell would you do that if you wanted to get into a maths intensive course like engineering

    Many people do, it's much easier than the 2u course and people do it to get a better ATAR.

    Yes but then they get to university and they're now required to do 4 unit level stuff and how are they going to go?

    You may have gotten a higher ATAR, but now you shot yourself in the foot when you're suddenly expected to learn things like calculus and all that, at the same time you need to learn completely new content such as matrices and stuff, while competing against students who are treating this completely as revision

    I'm sure not all of us had decided what we wanted to do in university during our subject selections... I'm not asking for criticism, I am asking of what I should be prepared for.

    Re: Mathematics for engineering

    I know a lot of white girls who do Biomedical Eng and civil eng, who did general.

    All they did was a foundation subject.

    Re: Mathematics for engineering

    unsw math does a general rigorous outline of mx1 and a bit of mx2 and systems of equations in practice in sem 1 then in sem 2 it's new stuff including differential equations, vector fields, vector spaces, eigenvalues/vectors and abstract theory for systems of equations in depth including kernel, image,etc

    in second year depending on type of engineering, vector calculus, statistics, further linear algebra are covered. some even do complex analysis in detail

    Re: Mathematics for engineering

    op you will need to put in a huge amount of effort in first year to keep up and a large amount of effort will be required prior to starting uni

    its possible bridging will not be adequate, in which case you can take a semester delay to focus on getting through first year maths by fundamentals courses and then start studying the rest of your engineering units.

    How are you going to explain this to a general student on the first day..

    Do General Maths students even see the number e?

    Do they even know what 'sin' and 'cos' are

    Yes (at least for triangles) – I checked their data sheet just before asking that (I was going to add whether they see sin and cos).

    Re: Mathematics for engineering

    So I'm guessing they haven't seen sin and cos as functions... and god help them if the angle is bigger than 90 degrees

    also they'd have to learn how to use radians


    It's just going to be a mess
