    in a typical marking scheme you may get something for this attempt

    Is this a straight line?

    a curve (equation or some kind of descriptor?)

    [this type of question is very hard and probably unlikely to come up in a standard exam these days]

    look at a similar question in this actual paper

    (Q8)

    Thanks it's a curve, well supposed to be! At least, that's what was drawn on in the answers! I was just trying to figure out what the 3pi/4 meant

    well the actual locus is not just a curve...
    it is the arc of a circle.

    The reason I attached the paper was to show you what is expected in a typical exam
    How many marks did you get out of the 4?

    PS: If I was writing a question, I would require

    • the equation of the curve
    • a proper sketch



    So this would be worth 10+ marks and your attempt will be worth ...

    Here's the question. It was posted a few posts before so I assumed you'd be psychic. Umm I counted 2 marks/4

    this is a question from a book ...
    It just say sketch ...

    well if you are satisfied with 2/4 for this type of question and the very low likelyhood of it coming up that is ok.

    I would never teach students how to do this type of question unless there were mathematicians to be.
