 May 21 awarded Nice Answer May 18 answered How to plot imaginary part of a function May 18 comment Flipping axis on a plot @s0rce For me it works. Did you copy the first Line of the code Options[flippeAchsen]=Union... ?

If you don't move, rotate, ... the grahphics with the mouse, the output will be an empty list. 2.) Yes, you have to Ctrl+Shilt+L the graphcs between the [ ]. The ll used in the definition will then be replaces by the graphic (which is a mathematica object like any other). May 9 answered Extract current viewing parameters from a 3D view? May 9 comment How to find the smallest root @Artes Ok that is what we call a "weak" monotonic function. May 9 comment How to find the smallest root I'm a bit confused. For a monotonic, continuous, differentiable function F with supremum c all values F[t] are less then c. Or am I missing something? Could you show the definition of F? May 9 answered About the number format in ticks May 8 comment Solving complex equations I think WRI has thougt about the Assumptions option of PowerExoand. I wrote the default were True, but it is Automatic. Look what Power[(a b)^n,Assumptions->#]&/@{Automatic,True} does. $Assumptions defaults to True, so Assumptions->$Assumptions is not appropriate for PowerExpand May 8 answered Solving complex equations May 8 comment Solving complex equations Not all functions with Assumtion Option do have the default Assumptions->$Assumptions. AFAIK the only one which doesn't is PowerExpand with default Assumptions->True. So Assuming works only for Functions having the default option Assumptions->$Assumptions.

May 7 comment Rationalize the Denominator by Default @rmv sorry I missed to copy this definition. I've added it to my answer.
