In document mode it's difficult to associate equations with correct labels.  Some time ago I mentioned something about plots within a document mode messing up underlying Labels so the labels shown are not what DocumentTools Retrieve would retrieve. 

If changes have taken place in a separate document they won't automatically update the linked document I believe until it is re-executed.

Ok, correct me if I'm wrong but it sounds like you create a particular worksheet with particular formatting applied to the fonts.  Then when you open the worksheet at some other time it has all changed. 

It could be that the scripts you changed your fonts to have all been defaulted somehow.  Are you not saving your changed fonts?  This may not be the reason I'm only offering a possible cause.

So if you want to remove a set with the condition k[d2]=k[d1] because it's not allowed then here's one way


seq(`if`(has(Sa1[i], k[d2] = k[d1]), 0, Sa1[i]), i = 1 .. nops(Sa1))


Conversly and probably a better way by using Carl Loves way using remove(s-> in your other question to use some way here, but I am unable to get the proper order of commands.




Maple can't load the underlying formulas in the cells from excel, only the visualized data.

In the short period of time I have.  You can use textplot with plot to get the curves in your plot.  I think it's possible to get the same linestyle in a legend, maybe not actually use the legend option but use a plot within a plot as the legend.

To get you started on a solution, combine textplot with plot.  Here's an example

point1 := {seq([(1/3)*x, -((1/3)*x-3)^2+4, "Δ"], x = 0 .. 15)}:
a := textplot(point1):
b := plot(-(x-3)^2+4, x = 0 .. 5):
display(a, b)

It may be available onsite at university computer labs for free use for students. But otherwise the full version student version is a discounted price for use at home.

First expand and then simplify will work.

simplify(expand( beta^(1/2)*(1+beta^(1/2))/(beta+beta^(1/2)) )







Use display to join plots.  You didn't mention what kind of straight line.  If you set your plot to a, and for example set one of these to b

b:=plot([3,y,y=2..6]) # a vertical line at x=3 from y=2..6


b:=plot([x,3,x=6..9]) # a horizontal line at y=3 from x=6..9

then join your plots with display




To hide equation labels just modify the color of the equation labels under styles to white.

Format -> Styles -> Equation label -> Modify -> color and change color to white.

For example, here is a way

plot(x^2, x = 0 .. 5, tickmarks = [[1 = `#munder(mn("one"),mo("___"))`, 2 = `#munder(mn("two"),mo("___"))`, 3 = `#munder(mn("three"),mo("_____"))`, 4 = `#munder(mn("four"),mo("____"))`], default])

Just a small tangent to your problem ... , if say you did re-organize the books to equalize the number of pages each person scanned, you could utilize the BinPacking1d proc by Carl Love created a while back.


BinPacking1d(equalized # of pages to read per person, in this case 4500/3,[books available[pages,books]])




Your output is 2DOutput so go through the Format menu at styles and choose 2DOutput and Modify.

I recommend getting rid of Debian, not Maple but seriously, it's more of a debian font issue than a problem with maple.


Maybe something like

S1 := map(allvalues,sol);
remove(has, S1, I)
