What is the first and second derivative of 3/(1+2(x^3)) ?
im tempted to do the quotient rule, but this looks weird to me...any advice would be greatly appreciated!!

  1. let u=(1+2x^3)

    then f= 3u^-1
    f'= -3 *u^-2 *u'

    but u'= 6x^2

    so f'= -3*6x^2 /(1+2x^3)^2

    When you see list of resultc click on:

    Calc101com Automatic Calculus,Linear Algebra and Polynomials
    When page be open clik option: derivatives

    When this page be open in rectacangle type:


    and click options DO IT

    You will see solution step-by-step

    By the way on this site you can practice any kind of derivation.
