Need help taking the derivative of these 2 equations

    Need help taking the derivative of these 2 equations

    sx+t

    sx^3+x+2t


    for the first i believe its
    y` = s

    for the second i am not sure if its but i believe its the first one

    y` = 3sx^2+1

    or

    y` = 3sx^2+1+2


    is this correct? the second one is kind of throwing me off with the b

    Re: Derivatives

    With respect to which variable? s, x, or t?

    to x, s and t are constants

    Re: Derivatives

    First off, these aren't equations. They are just expressions.
    Yes.
    Yes.
    No. From what you said in a later post, s and t are constants, so d/dx(t) = 0.
    What b?
