    Need some derivatives guidance

    Finding the derivatives of

    f(x)=e^(1-x^2)

    f(x)=ln(x^3-1)

    f(x)=3xe^2x


    Anything will be greatly appreciated, I am just trying to figure out exactly how to solve these, I understand using the different rules..but, I am still having trouble seeing how you get this derived. Thnx.

    Solution to the first one

    f(x)=e^(1-x^2)

    I believe the correct answer for this is -2e^-2x

    I got that from the base * the derivative of the exponent. Am I completely off here? I am still being troubled by the others but, I believe I got this one.

    Thanks

    This is just chain rule.

    (e^u)'=u'\cdot e^u & (\ln u)'=\frac1u\cdot u'.

    Of course, recall the product rule.
