Finding the rate of change

  1. Jul 24, 2009 #1
    the height h(x) in meters above the ground of a parachute varies with her horizontal distplacement x in meters from a landing target on the ground as h(x) = 50sin^-1 (0.1x). what is the rate of change of h with respect to x at x = 6m?

    i was wondering of someone could help me with this question :)

    What is the derivative of h(x) = 50sin^-1 (0.1x)? That's all this is asking. Do you know the derivative of arcsine?

    is it
    1 / sqrt(1-x^2)

    :)

    yes so now you know

    [tex]\frac{d}{dx} (sin^{-1}x)= \frac{1}{\sqrt{1-x^2}}[/tex]

    what is d/dx( sin-1(0.1x)) ?
