There used to be a sort by original posted date.  I don't know what happened to that.  There should also be options to sort by last action AND most recent post in the thread. 

Interestingly

[[''(z1+z2)'']](x) seems to be equivalent to [[map(z1+z2,x)]]

I can create a new character style Units with a different color as a workaround but it's cumbersome to have to switch character styles during entry and units output color is black anyway. 

Not sure, maybe gfun?

with(gfun):
ratpolytocoeff(g(x),x,3)
                

also remember if you want to expand denominators you need to use normal with the expanded option

normal(g(x),expanded)
                  

@acer I chose wishlist for Maple 2019 for the simple reason that some requests made here in this thread will still make it into Maple 2019

@Daniel Skoog The general idea was for the AudioTools package to support mp3 file types.  Functionality like convert to mp3 file types.  I don't know if this is possible but also have the functionality for loading only portions of the mp3 file say for example the middle 10% of the file, last 10%.

Also Noise filtering, frequency reducing sounds below, above or around specified frequencies, more sound analysis and manipulation in general.  Pattern finding, maybe sound matching (ie. see if a particular sound exists in a later portion of the sound file)

I thought exactly that.  Hopefully some ideas mentioned here will make it to 2019 - however maybe other ideas here could also be taken into account for 2020

mp3 supported file types for the AudioTools package. (ie. be able to directly read in an mp3 file using Maple) 

I've taken the liberty to transcribe his code into a maple worksheet (I've highlighted the gobbledygook)

Maybe this could help us solve the OP's issue.

Maybe the AddElement command could be used for this?

@herclau .. is it just for fun?  It seems interesting, but what sort of application would that have?  Depending on which portion of the ellipse you choose, the average radii would never be the same.  Even within the same eliptical sector, depending on how many divisions you choose the average will change. 

@herclau let's see if I can clear this up. 

You want some numbers of radii's n from one side to the other in the arc from the middle of the focii's and you want the average of them.  So having n divisions the average would then be ( r₁+r₂+..+r_n)/n.  I think that is what you are looking for?

Thanks, I was playing with width but couldn't get it to work (yes programatically).  I was hoping it was just a simple undocumented argument command option that could be added in the main line. 

Thanks Carl and Kitonum. 

Regarding the math container, I mean to move the check answer and try again buttons closer to the question.

Just thought of it now, I'd like to add a timer and score tracking.  But I don't know if it's possible within the Grading[Quiz] package.

Well it was slightly different, in that he was asking how to shade between the contours. 

I had the idea of trying (before I tried last night which failed to work) something like using the coloring option in contourplot to something like coloring=[coloring=["red","yellow"],"Green"].  I thought by nesting colors in the coloring would work by shading more than just 2 colors, obviously of course after getting access to maple and trying it, it did not work.
