+Differentiation of Multiplicative equations are performed by the product rule.  This is defined as $\frac{\mathrm{d}}{\mathrm{d}x} f(x) \cdot g(x) = f(x) \cdot g^{\prime}(x) + f^{\prime}(x) \cdot g(x)$.  There are some minor exceptions, if $f(x)$ and $g(x)$ are numeric, then the result is the product of the two; if either $f(x)$ or $g(x)$ is numeric and the other is not, then the numeric is placed in front of the other derivative of the remainder.
