    Hey, I just need help on where I've gone wrong on this question.

    4) Find the equation of the tangent to the curve , at the point where .

    My working:

    When





    And





    Which is the point


    For ,







    Therefore,

    , when


    Hence, the equation of the tangent is given by






    It's probably just a simple mistake that I've made, or just completely forgot about a certain step. I've checked over my work a few times though; I'm at a loss to how it's incorrect.

    Thanks!

    Sorry, I don't follow :c. What have I done wrong in my working out?

    It's not that. I just don't realise how what you've said below is relevant. Probably just going over my head, but surely there is only one tangent to t=2.

    The Cartesian equation for the curve is , after all.

    Try graphing it.

    This is the bit I don't understand.

    But z=0 for this curve... That's what I'm basing my answer on.

    Obviously, because z isn't specified.

    Ah, I didn't use the inverse of as part of the chain rule. My bad .

    Thanks.

    What crap.

    It doesnt mean that either version of a tangent is incorrect or bad advice.
    If you don't give the actual definition then it's both incorrect AND bad advice.

    Yet if you give the,right definition in the wrong place it doesnt make you appear correct our definition of correct/wrong being completely relative to the observer. Wheras correct maths is always the same
    You're more often wrong than right.
    Please stop.

    Your definition was irrelevant. The context of tangent was crystal clear from the OP--and you choose to ignore that and mislead the poster. If you were just providing an extra tidbit of information, like a "did you know" then you should have made that clear--you didn't. You either didn't understand the OP, don't understand the math, are trolling or aren't being careful enough to distinguish between what relevant and helpful and what's trivia. I'll assume it was the latter--so just be more careful in the future. Thanks

    m= 144 and not 148

    so , y-31=144(x-12)
    y= 144x-1728
    y-31=144(12)-1728
    y-31=1728-1728
    y-31=0
    y=31
