Homework Help: Compute the following derivatives

  1. Feb 2, 2013 #1
    1. The problem statement, all variables and given/known data

    compute the following derivatives using the product rule and quotient rule as necessary, without using chain rule.

    2. Relevant equations

    d/dx ((sin(x))^2)

    3. The attempt at a solution

    =(sin(x))(sin(x))
    =(cos(x))(sin(x))+(sin(x))(cos(x))
    =2(sin(x))(cos(x))

    Looks fine to me. The final answer is equivalent to sin(2x) [trig identity] in case you want a slightly simpler form.
