    Nth derivative

    The nth derivative of the function f(x)=1/1-x^2 at the point x=0, where n is even, is

    A n (n 2) B.0 C. n!

    Thanks for the help!

    I will guess that "1/1 - x^2" actually means "1/(1 - x^2)". Please correct if this is wrong.

    What have you gotten for the first few evaluated derivatives? What pattern do you think you see?

    Please be complete. Thank you!

    yes it is : "1/(1 - x^2)" (sorry for the confusion)

    i derived it 2-3 times using quotient rule and d expression got more and more complicated.
