Differentiating a quotient

  1. Oct 6, 2008 #1
    1. The problem statement, all variables and given/known data
    X / 1+sinX

    3. The attempt at a solution
    Quotient rule

    (1+sinX)(1)-X(1+cosX) / (1+sinX)2


    1+sinX-X-XcosX / (1+sinX)2

    But when I look at the answer in the back of the book, it's wrong.

    Re: Differentiate

    Is the derivative of 1+sinX really 1+CosX? I thought the derivative of 1 was zero. ;0)
