Hi,
as someone reported yesterday in the Spanish Maxima list, the following
limit is not working:
limit( (log(1+x^2)-2+2*cos(x))/((sin(x))^2+2*sqrt(1-x^2)-2),x,0);
In version 5.19.0 it used to give the wrong result "minf". Now in
version 5.20.0 Maxima gets stuck and does not return anything.
It is easy to see that the correct result is 5/7.
Regards,
Jaime
