\begin{eqnarray*} \frac{1}{f_{1}}\frac{df_{1}}{d\alpha } & =& \frac{1}{\alpha } \\ \frac{1}{f_{2}}\frac{df_{2}}{d\alpha } & =& -x^{\alpha }\log \left( x\right) -\alpha x^{\alpha -1}\frac{dx}{d\alpha } \\ \frac{1}{f_{3}}\frac{df_{3}}{d\alpha } & =& \log \left( x\right) +\left( -k+\alpha \right) x^{-1}\frac{dx}{d\alpha } \end{eqnarray*}
