Yes, probably there is no clean solution. (see my reply the following post).
For periodic functions, the range could be cut after a few periods.
Just for your information: Mupad plots the function sin(x) within [-5,5]
The same for sin(8*x) and sin(0.1*x). So it appears that they have chosen a
fixed range for every function.
I have also tried x/(x^2-100): the picture displayed is in the x range
[-5,5] and in the y range [-0.06,0.06].
--> Note that asimptotes (at +-10) are NOT shown. So that it appears Mupad
has gone for a not so smart solution.
I guess the Mupad 'marketing office' maintains that feature is appreciated
by users, as a starting point, if they did not care to set the range.
