Suppose one had 2 levels of evaluation and you only wanted to go back 1 level to uncover it's original components.  That would be no problem if nothing was cleared, but very unfortunate if it did. 

example,

a:=5*x^2-3*y^3:

b:=3*x^2+10*y^3:

c:=a+b
               

I came across this post http://www.stiglerdiet.com/2012/02/10/mathematica-a-love-story/

and in the commented section near the end someone mentions this can not be elegantly done in Maple.  I would like to disprove this comment.  He says "There’s NO WAY any numeric language like R or Maple can try to do this."

I don't believe it, and I welcome anyone to disprove his...

I noticed in math mode the alt windows shortcut codes won't work but in text mode it will, understandably.

ie.  alt-0125 }   alt-0254 þ   etc...

Is there a way to get maple to output the list of alt codes?

I created a quick procedure to produce a violin plot and I would like some help to make it better. 

I would like it to show a more accurate distribution of the data, I interpert the graph as the data having negative values which of course there is none.  How can we fix that? I realize we can just set the range=min(data)..max(data) but then I loose the violin tips and I would need to place a line to cap the top and bottom.

So how can we create a violin...

Maple plots pareto charts slightly different than what I usually see.  It might be nice to include an option in the pareto to flip the axis.  But I think maybe the reason maple has pareto plotted this way (having the x and y axes flipped), is because the x-axis is unable to angle descriptors (an option I have asked to be added in the past)

Using the pareto example from maple help, when I rotate and flip the chart from plottools where did the y axes labels go?
