    Differentiation of fractions

    I'm sorry that this is such a small question, but I haven't done Calculus in years.

    I have to differentiate (t-(t^3)/3) and (t+(t^3)/3).

    Thanks.

    This depends on if the denominator of the fraction contains the variable with which respect you are differentiating. In your examples this is not the case. Remember the fact that \frac{d}{dx} (cf[x]) = c*\frac{d}{dx}f[x]. In both of your examples, pull out the 1/3 in front.
