[Maxima] integrate 1/x

[Barton Willis]

Because integrate(1/x,x) = log(abs(x)) is OK on either the negative or
positive
real axis, but it is not OK in the complex plane. There is a switch that
controls
this, however.

 (%i199) integrate(1/x,x);
 (%o199) log(x)

 (%i200) integrate(1/x,x), logabs : true;
 (%o200) log(abs(x))

If you want logabs to be true, do

 (%i201) logabs : true;
 (%o201) true
