Calcule sumas que involucren funciones especiales 

Calcule sumas indefinidas y definidas que involucran GammaRegularized y BetaRegularized.

In[1]:=

X Sum[GammaRegularized[k, z], k]

Out[1]=

In[2]:=

X Sum[k k! GammaRegularized[k, 3], {k, 2, n}]

Out[2]=

In[3]:=

X Sum[3^(-k) BetaRegularized[2, k, 3] , {k, 1, \[Infinity]}]

Out[3]=
