    Integrations Volume Question Need Help! :(

    Recall V=\pi\int^{a}_{b}{y^{2}}\, dy You can integrate separately for the corresponding areas by letting: y^2=x^4=\pi\int^{1}_{0}{y^{2}_1}\, dy y^2=[(x-2)^2]^2=\pi\int^{2}_{1}{y^{2}_1}\, dy \pi\int^{1}_{0}{y^{2}_1}\, dy+\pi\int^{2}_{1}{y^{2}_2}\, dy

    Units of Study Questions

    You need a minimum of 12 credit points of mathematics for your first year of BSc. You do not need to do mathematics to transfer to science but it would definitely be an advantage as you can have more credits transferred. Credits are similar to 'units' from HSC where each subject is usually worth...

    PHYS1001 Prerequisites

    Prerequisite is a minimum mark of 65 in HSC physics. University physics is almost all calculations, thus making a huge portion of HSC physics irrelevant whilst emphasizing more on your mathematical background. Plus, the course outline says PHYS1001 should be studied concurrently with MATH1XX1...

    How do you sketch a function?

    Find y-axis x^7=-1;x=1 A function where the highest degree is the only variable f(x)=x^{n}+c (where n is odd), the curve usually looks similar the cubic function {f(x)=x^{3} for \{n{\in}\mathbb{R}|n{\geq}3\} expect the "horizontal point of inflection" looks longer depending on the degree. The...

    Differentiate (2e^-x)lnx

    Let u=2^{-x} and let v=lnx u'=-2e^{-x};v'=\frac{1}{x} The product rule: \frac{d(f(u)g(v))}{dx}=u'v+v'u Hence: \frac{2e^-{x}}{x}-2lnxe^{-x}

    Need help with two questions (Integration)

    I did dy because we are integrating with respect to y. You need to do this in order to find the area along the y-axis \int^{2}_{1}y^\frac{-1}{2}\, dy = \frac{y^\frac{-1}{2}}{\frac{1}{2}} = [2\sqrt{y} ]^2_1

    Need help with two questions (Integration)

    Q4. y=\frac{1}{x^2} becomes \frac{1}{\sqrt{y}} Thus, \int^{2}_{1}\frac{1}{\sqrt{y}} \, dy self explanatory from there on; Q6. A1, \int^{2}_{1}x^2 \, dx = [\frac{x^3}{3}]^{2}_{1}=\frac{7}{3} A2, x^2=y = x=\sqrt{y} = \int^{4}_{1}{\sqrt{y} }\, dy = [\frac{2(y^{\frac{5}{3}})}{3}]^4_1 =\frac{14}{3}...

    (Integration), where did I go wrong?

    Maybe you should try to reattempt the question if you haven't, then post if you're have difficulties.

    (Integration), where did I go wrong?

    Because you're adding the two areas together

    (Integration), where did I go wrong?

    In before this goes for 3 pages: \int^{0}_{-1} -x^2 + 3x + 2 \, dx+\int^{2}_{0} -x^2 + 3x + 2 \, dx = [\frac{-x^3}{3}+\frac{x^2}{2}+2x]^{0}_{-1}+[\frac{-x^3}{3}+\frac{x^2}{2}+2x]^{2}_{0} = \frac{7}{6}+\frac{10}{3}=4\frac{1}{2}

    Raw marks

    It does depend on your external + internal marks and also how well the subject aligns during your HSC year. To get an idea for previous years, have a look at the raw marks database: http://community.boredofstudies.org/461/atar-hsc-marks/324426/updated-raw-marks-database-sortable-excel-file.html

    Year 10 Science Research Project Ideas?

    Couldn't be bothered to do anything fancy, grew mould on bread. Measured temp and humidity with a hygrometer, ended up growing penicillin (or something similar) that killed off the surrounding mould.

    Advice to someone that done general maths and wants to do engineering?

    You can do a bridging course for 2U or do MATH130 in the first semester before math135 (which has a prerequisite of a B4 in 2U) and physics.

    Calling all Aeronautical (Space) engineers

    You can start 2nd semester of they have it (usyd usually only has engineering starting first semester though), otherwise yes, it is VERY calculus heavy. If you look at the CUSP you have 4 math course, 2 (differential and integral) calculus course not to mention PHYS1001 and engg1802 which also...
