I think there's a bug with fractions
Limit[ ln(x) / x, +infinity ] -> OK
Limit[ ln(x) / (3x), +infinity ] -> BAD
Limit[ ln(x) / 5, +infinity ] -> BAD
LimitUp[ln(x)/2, 0] -> BAD
Limit[ cos(x) / (x^2), +infinity ] -> OK
Limit[ cos(x) / (5*x), +infinity ] -> BAD
If you have a number in denominator, Geogebra doesn't work fine.
Geogebra 4.1.153.0 and 4.1.41.0 Webstart (Java 1.6.0_26)
