4 unit maths questions

[conic curve]

This question is kind of irrelevant to the thread but I'll ask it here: if you plan to do extension 2 maths, then what "prerequisites" do you need for each and all of the following topics: complex numbers, graphs, polynomials, conics, integration, volumes, mechanics and Harder 3U

[RuiAce]

The entire Mathematics Extension 2 course ASSUMES that you have a bare minimum knowledge of HSC 2U Mathematics.

Complex numbers does not require much of MX1 however a bit of circle geometry ties in.

Graphs requires any bit of graphing you know from previous courses.

Polynomials requires complex numbers as well as the entire MX1 polynomials topic

Conics requires MX1 parametric representation to be covered.

Integration just requires every integral that can be computed in up to MX1

Volumes calls upon integration.

Mechanics requires up to MX1 Applications of Calculus to the Physical World

The answer to harder 3U is trivial.

For complex numbers, I thought there was triginometry as well as algebra and some graphing

Does graphs require calculus of any sort?

I heard polynomials needs triginometry as well

Conics doesn't require complex numbers at all? What about some graphing skills?

Volumes and Integration sound like the same thing. Mainly because they both have integration

Isn't some mechanics based on some yr 11 physics as well (i.e. Moving about)

[RuiAce]

Like I said, the course assumes you have a bare minimum of HSC 2U Mathematics. Being specific about where what is applied is a bit of a redundancy here. Trigonometry is mostly 2U.

(Some 3U further trigonometry is required for complex numbers though I'll give that.)

Also, volumes and integration (whilst having overlaps) are definitely not the same thing. Ext 2 integrations goes well beyond that of Ext 1, and Ext 2 volumes actually forces you to understand how volume formula are derived and proven. not how to just write the integral out.

And I'd say the converse is true. I'd say Moving About is based off Mechanics and the 2U/MX1 Appns of Calc topic.


Conics is in no way whatsoever related to complex numbers as far as the MX2 course goes. As for graphing? The graphing skills you need for conics were all taught in 2U.
