integral de serie geométrica

∫ [ e^{x}·( (x^{(n+1)}+(-1))/(x+(-1)) ) ] d[x] = e^{x}+∑ ( x^{(k+1)}·er_{m;k+1}(x) )


∫ [ e^{x}·( (x^{(n+1)}+(-1))/(x+(-1)) ) ] d[x]= ∫ [ e^{x}+∑ ( e^{x}·x^{k} ) ] d[x]


∫ [ e^{(-x)}·( (x^{(n+1)}+(-1))/(x+(-1)) ) ] d[x] = (-1)·( e^{(-x)}+∑ ( (-x)^{(k+1)}·er_{m;k+1}(-x) ) )
