    Good. I'm getting impatient as hell. Can't say I didn't try to.

    S1/17 WAM Predictions

    I'm not sure how it works at MQ, but at UNSW whole number marks is the norm and an effort will be made to round marks up where necessary. This may be different at MQ due to the use of the GPA and a focus on whether or not you got HDs/DNs/CRs instead of a number, but you should keep this into...

    S1/17 WAM Predictions

    As RoT explains it may not be fully revised but if you go back a page I think we have some evidence that ECON1203 has been entered.

    S1/17 WAM Predictions

    Um, yes, it is impossible. Because the A in WAM stands for average. The average of 3 courses has a decimal value of .333 or .667, not .25, .5, .75

    It's for all the courses that have been entered so far

    S1/17 WAM Predictions

    If there's no decimal point then at this point in time it's most likely that only one of your courses has been added Only MATH2011 is said to be out.

    What's your decimal point on right now? (mreditor probably asked his mates doing the course to see if their's changed and compared)

    That feels when you're a law student Oh yeah this year was different math2111 was easy but math2601 was hard... Why not be a snake like them and get HD then dafuk Cough law students cough myUNSW -> Stream declaration -> {Go declare a stream} -> Wait for a view button to show up -> WAM is...

    Re: HSC 2017 MX2 Integration Marathon \begin{align*}I_n&=\int_0^1\left(\frac{x^n+x^{n-1}-x^{n-1}}{\sqrt{x+1}}\right)dx\\ &= \int_0^1 \frac{x^{n-1}(x+1)}{\sqrt{x+1}}-I_{n-1}\\ &\stackrel{IBP}{=}\frac{x^n}n \sqrt{x+1} \bigg|_0^1 - \frac{1}{2n}\int_0^1\frac{x^n}{\sqrt{x+1}}-I_{n-1}\\ \implies...

    MATH2601 Higher Linear Algebra

    Completely forgot about that one. _________________ \\\text{Suppose }Q\in M_{n,n}\text{ is unitary. Prove that all its eigenvalues }\lambda\text{ satisfy}\\ |\lambda|=1

    MATH2601 Higher Linear Algebra

    This is a highly open-ended question and everyone's opinion might be different. What's the easiest proof (or would be a very easy proof) of the Cauchy-Schwarz inequality to memorise?

    MATH2601 Higher Linear Algebra

    No more questions for this sem after tomorrow. __________________ \\\text{I forgot how to use my field axioms.}\\ \text{Prove that }a0=0\text{ for }a\in \mathbb{F}

    MATH2111 Higher Several Variable Calculus

    \frac{d}{dx}\int_0^{u(x)}f(v(x),y)dy = u^\prime(x) f(v(x),y) + \underbrace{\int_0^{u(x)}\frac{\partial f}{\partial x}(v(x),y)dy}_{\text{how to simplify this further?}}

    MATH2111 Higher Several Variable Calculus

    Yeah the latter lol ________________________________ Just a yes or no answer please because I can't just tell what to use immediately. I know that it converges pointwise to the zero function. \text{Does }f_k(x)=\begin{cases}k & \text{if }0 < x \le k^{-1}\\ 0 & \text{otherwise}\end{cases}\text{...

    MATH2111 Higher Several Variable Calculus

    That was definitely the starting point, but that just asserted that there exists an open set V\subseteq U that is open, not \textbf{f}(V)\subseteq \textbf{f}(U) right? Image of an open set under a continuous function might not be open

    MATH2111 Higher Several Variable Calculus

    I thought I had it but I probably didn't. Not sure what I could possibly do next after Jg(f(\textbf{a})J\textbf{f}(a)=\textbf0 I really don't feel like that should be the final answer either. Any further guidance? dying
