Homework Help: Differentiating K sin(Gt + 5)

  1. Oct 8, 2011 #1
    1. The problem statement, all variables and given/known data

    if y = K sin(Gx + 5)

    what is dy/dx

    2. Relevant equations

    y=sin x

    dy/dx = cos x

    3. The attempt at a solution

    y = K sin(Gx + 5)

    dy/dx = KG cos (Gx +5) (1)


    dy/dx = KG cos GX + 5 (2)

    i think it is (1)

    is this correct or it is non of these (other)?

    Why would you think it is (2) in the first place?
    (1) is certainly correct, but your doubt indicates you are not quite familiar with the rules of differentiation yet.
