Question 314358
{{{ln((x/(x-1)))+ln(((x+1)/x))-ln((x^2-1))=ln((x/(x-1))((x+1)/x))-ln((x^2-1))
}}}
{{{ln((x/(x-1)))+ln(((x+1)/x))-ln((x^2-1))=ln((cross(x)/cross(x-1))(cross(x+1)/cross(x)))-ln((x^2-1))
}}}
{{{ln((x/(x-1)))+ln(((x+1)/x))-ln((x^2-1))=ln(1)-ln((x^2-1))
}}}
{{{ln((x/(x-1)))+ln(((x+1)/x))-ln((x^2-1))=0-ln((x^2-1))
}}}
{{{ln((x/(x-1)))+ln(((x+1)/x))-ln((x^2-1))=ln(1/(x^2-1))
}}}
