    PieceweseRule(subfunctions=[(ArctanRule(a=1, b=-3, c=6, context=1/(6 - 3*x**2), symbol=x), False), (ArccothRule(a=1, b=-3, c=6, context=1/(6 - 3*x**2), symbol=x), x**2 > 2), (ArctanhRule(a=1, b=-3, c=6, context=1/(6 - 3*x**2), symbol=x), x**2 < 2)], context=1/(6 - 3*x**2), symbol=x)

  1. Añadimos la constante de integración:

    {2acoth⁡(2x2)6for x2>22atanh⁡(2x2)6for x2<2+constant\begin{cases} \frac{\sqrt{2} \operatorname{acoth}{\left(\frac{\sqrt{2} x}{2} \right)}}{6} & \text{for}\: x^{2} > 2 \\\frac{\sqrt{2} \operatorname{atanh}{\left(\frac{\sqrt{2} x}{2} \right)}}{6} & \text{for}\: x^{2} < 2 \end{cases}+ \mathrm{constant}

Respuesta:
