    do not laugh at my misery. It's not easy being different! (I constantly have to differentiate! < that's my attempt at a joke)
    surely you would want to integrate?

    Saying change in sign will get you the mark.

    Mentioning the graph is continuous is another point on the MS, but you don't have to say it.

    y = arcsinx

    differentiate with respect to x
    siny=x

    therefore:dx/dy= cosy
    (and no dy/dx!)

    i got carried away teaching myself, but then the vectors and integration got me so i stopped

    y = arcsinx

    x = siny

    1 = cosy\frac {dy}{dx}

    \frac {1}{cosy} = \frac {dy}{dx}

    \frac {dy}{dx} = \frac {1}{\sqrt {1 - x^2}}

    :awesome:
