    HSC 2018 MX2 Marathon

    Welcome to the 2018 Maths Ext 2 Marathon

    Post any questions within the scope and level of Mathematics Extension 2. Once a question is posted, it needs to be answered before the next question is raised.
    This thread is mainly targeting Q1-15 difficulty in the HSC.

    Q16/Q16+ material to be posted here:
    HSC 2017-2018 MX2 Marathon ADVANCED

    I encourage all current HSC students in particular to participate in this marathon.

    Have fun ^_^

    i) x^2+y^2=1

    ii) x^2+(y-im(z))^2=1

    I've probably misinterpreted the question given it does seem overly simple

    I made a typo in writing the first question, it should be fixed now. Your second answer however has a 'z' there but this is not a proper cartesian equation for the locus, you want only 'x's and 'y's
