Gamma(x)
$$\Gamma\left(x\right)$$
gamma(x)
The first derivative [src]
Gamma(x)*polygamma(0, x)
$$\Gamma\left(x\right) \operatorname{polygamma}{\left(0,x \right)}$$
The second derivative [src]
/         2                        \         
\polygamma (0, x) + polygamma(1, x)/*Gamma(x)
$$\left(\operatorname{polygamma}^{2}{\left(0,x \right)} + \operatorname{polygamma}{\left(1,x \right)}\right) \Gamma\left(x\right)$$
The third derivative [src]
/         3                                                            \         
\polygamma (0, x) + 3*polygamma(0, x)*polygamma(1, x) + polygamma(2, x)/*Gamma(x)
$$\left(\operatorname{polygamma}^{3}{\left(0,x \right)} + 3 \operatorname{polygamma}{\left(0,x \right)} \operatorname{polygamma}{\left(1,x \right)} + \operatorname{polygamma}{\left(2,x \right)}\right) \Gamma\left(x\right)$$
