Should not the following two commands produce same solution?

f:=x->(x^2+3*x-4)*cos(x^2+3*x-5);
PDEtools:-Solve({f(x)=0,0<x,x<2},x);
solve({f(x)=0,0<x,x<2},x);

This is what the result looks like

Why Solve gives one solution and solve gives 2? Is this expected or a bug?

btw, the solution from solve is also not complete. There are 5 roots not 2.

Student:-Calculus1:-Roots(f(x),x=0..2);

Why when going to user pages and clicking to see the next page, Mapleprimes gives

https://mapleprimes.com/users/?page=2

This happens for each page after the first one which shows OK.

Do others see this also?

I do not use table data struct in Maple and could not find anything in help on how to do this.

given a table T such as the following, typing indices(T) shows there are more than entry in each index

indices(T)

[[-0.687272727272727, -0.687272727272727, 1.],   [2.25818181818182, 2.25818181818182, 1.]], 

  [[-2.47, -1.47, 2.], [0.53, 1.53, 2.]], 

  [[0.245, -2.755, -2.], [2.745, -0.255, -2.]], 

  [[-2.6, -0.6, 3.], [0.379, 2.379, 3.]], 

  [[2.659, -1.341, -3.], [4.652, 0.652000000000001, -3.]], 

  [[-3.178, 0.822000000000001, 5.], [-1.185, 2.815, 5.]], 

  [[0.0672727272727271, -0.932727272727273, 0.], [3.06181818181818, 2.06181818181818, 0.]], 

  [[2.8895, -2.1105, -4.], [4.3895, -0.6105, -4.]], 

  [[1.01, -0.99, -1.], [4.02571428571429, 2.02571428571429, -1.]], 

  [[-3.63, -0.63, 4.], [-1.13875, 1.86125, 4.]]

In the above each entry in table has 2 indices. I want to keep only the first index in each entry so that it has only one, to become this

[[-0.687272727272727, -0.687272727272727, 1.]], 

[[-2.47, -1.47, 2.]], 

[[0.245, -2.755, -2.]],

 [[-2.6, -0.6, 3.]], 

[[2.659, -1.341, -3.]],

 [[-3.178, 0.822000000000001, 5.]],

 [[0.0672727272727271, -0.932727272727273, 0.]], 

[[2.8895, -2.1105, -4.]], 

[[1.01, -0.99, -1.]], 

[[-3.63, -0.63, 4.]]

And keep everything else as in in the Table. Just need to adjust the indices to be one entry instead of 2 or more.

Here is an example of such table

T:=table([([-.687272727272727, -.687272727272727, 1.], [2.25818181818182, 2.258181\

Is it possible to do this in code?

Maple 2025.2

I am not able to find place in help which lists which changes interface(typesetting = extended); makes compared to interface(typesetting = standard);

Reason  I am asking, is that in interface(typesetting = extended); Maple adds a small annoying "dot"  between each term for multiplication, which is not there in standard.

Is there a place in documentation that mentions this as part of extended? Where to find it?

in Matlab and Mathematica it is possible to put the labels in contour plot, directly on the lines (with nice positioning).

This makes it much much easier to see the level of each contour line since the values are on the lines,  without having to jump to the legend and guess the color and try to visually match colors with the plot.

For example, in Matlab

clear; close all;
x = 0:0.05:20;
y = 0:0.05:15;
[x,y] = meshgrid(x,y);
z = (11-x-y).^2 + (1+x+10*y-x.*y).^2;
[C,h] =contour(x,y,z,10);
clabel(C,h)

gives

In Maple

f:=(11 - x - y)^2 + (1 + x + 10*y - x*y)^2:
plots:-contourplot(f, x=0..20, y=0..15,
         legend=true,
         contours=10,
         'axes'='boxed',
         legendstyle=[location=right], 
         colorscheme="DivergeRainbow");

Is there a way to tell Maple to put contour labels on the "middle" of the level lines (contour lines) similar to what Matlab does?

I see no such option in https://www.maplesoft.com/support/help/maple/view.aspx?path=plots/contourplot
