according to help under Explore, it says

I wanted to add title at top of the Explore window. But title do not show. 

Explore(plot(a*sin(b*t),t=0..10),
   parameters=[              
        [a=1..20],
        [b=1..20]
        ],
  initialvalues=[a=6,b=5],placement='right',width=300,'title'="My Explore");

I was expecting My Explore to show at top of frame above. What Am I doing wrong?

Maple 2025.2

Is this a bug?  Or one can not mix slider for one variable and textarea for second variable in Explore?

Or do I need to initialize the textarea is special way? Nothing in help shows an example with textarea and slider together.

interface(version);

`Standard Worksheet Interface, Maple 2025.2, Windows 10, November 11 2025 Build ID 1971053`

No textarea , works OK

 

restart;

Explore(plot(a*sin(b*t),t=0..10),
   parameters=[              
        [a=1..20],
        [b=1..20]
        ],
  initialvalues=[a=6,b=5],placement='right',width=300);

 

 

Change one slider to textarea, now error

 

restart;

Explore(plot(a*sin(b*t),t=0..10),
   parameters=[              
        [a=1..20],
        [b,'controller' = 'textarea','label'="b" ]
        ],
  initialvalues=[a=6,b=5],placement='right',width=300);

Warning, expecting only range variable t in expression 20*sin(b*t) to be plotted but found name b

I am not able to find an example or how to do this in help.

In Explore, when making a slider, using say 

parameters=[  [ a=1..1000 ], .....]

Is there is a way to tell it to increment "a" by say 10 for each movement of the slider using the mouse? it seems to default in this case to 1 each time.

Actually it is very hard now to make the slider go to the exact value I want. Is there a way to better control what value "a" should be?

In Mathematica, slider supports increment. Also it is possible to open each slider and then click on + and -  in the small window that opens below the slider, where now each click on + now moves the slider by the increment one decides on.  But in Maple I see no place to tell it what increment to use?

If I try this (similar to when using seq command, as in seq(i, i=1..1000,10), it does not work

[ a=1 .. 100, 10 ]

Hoping it will increment/decrement by 10 each time, it gives error.

Imagine a slider that goes from 1 to 10,000. Then how will one control the slider to be say exactly 5,550 ?  It is impossible now. Here is an example

Explore(plot(a*sin(x),x=-3*Pi..3*Pi,'gridlines'),
   parameters=[[a=1 .. 10000]],
   initialvalues=[a=1000],
   width=500,placement='right');

Now try using the slider above to make it go to a=5550. 

very hard to control the slider as it is very sensetive to slider motion, a small touch makes it move by large amount.   

I was hoping that if I can make it move by say 10 at time, so it will be at least easier to control.

Any suggestions?

I see a web page called Slider Component   but have no idea if this is related to Explor or not and how to use it there.

I know I can change the slider to "controller = textarea", and this way I can type in the value I want instead of using a slider. But want to see first if standard slider has a way to allow changing the increment amout. If not, then may be will use textarea instead of slider.

I have not used Explore command alot. Just starting to learn it. But I am stuck on improving the basic look of it.

There are way too much space between sliders and too much white space between the sliders and the plot itself. Also the fonts used below the sliders are too large and do not even know how to remove them or make the fonts smaller.

Looking at the help page, I do not see options to adjust these. But help pages are very hard to read to find an option.

Here is an example. I am using worksheet, with 100% default zoom.

Explore(plot((b+0.7)*sin(x/(a+1))/x+b, x=-4*Pi .. 4*Pi, view=-2 .. 6,gridlines),
        a=-2.0 .. 1.0, 
        b=0.0 .. 3.0,
        width=300,placement='top');

This is the output

I'd like to be like this

Overall, even though Explore works, I find the look of it pretty bad actually due to the above issues. It does not look professional and polished.

This is a big problem, because if there are 4 or 5 sliders, now one can not even see the plot itself when changing the sliders, because one has to scroll down to see the plot now and then scroll back up to reach the top sliders to move them.  Even on Large monitor.

Is there a trick to control the spacing between sliders and the main body which is the plot window? Removing all wasted white space and making sliders font smaller for numbers below the sliders or remove them will go long way to making Explore command output look better.

t := (5/9)*Pi;
e:=tan(t) + 4*sin(t);

is -sqrt(3)  but how to make Maple show this?

This is what I tried

t := (5/9)*Pi;
e:=tan(t) + 4*sin(t);
convert(e,radical);
simplify(e,trig);
simplify(e,constant);
allvalues(e);

 

The command "is" and "identify" knows this

is(e=-sqrt(3));
identify(evalf[32](e))

In Mathematica, FullSimplify can do it.

 

Any suggestions in Maple to simplify like the above?

Maple desperately needs a new full_simplify() command.

Having to keep trying different commands by trial and error in the hope one works is not the right way to do things.
