I opened my SideBisectorsKRS.html file with SeaMonkey and the page that came up had a message stating that JAVA is not installed on my computer (but it is). So the link to the applet created using GeoGebra was not given. I would appreciate any suggestions you may have to fix this. Thank you.

If I understand your comment, you're wondering why the apple does not appear in the SeaMonkey Composer window. What instead appears is the alternate text for when an applet does not load. In the Composer window, which is a WYSIWYG text editor, this is expected, since the Composer is not a browser. If on the other hand you opened the html file in the browser of SeaMonkey, that is another question. Does your file load correctly in your usual browser?

Yes, the file does load correctly in my usual browser. Thank you - you answered my question.

I would like to be able to either rename the file I uploaded or get it delete. The file name is parabolaVert32ABC.ggb. Correct name should be parabolaVert40ABC.ggb. If you delete it I will take care my page, in fact I have deleted the link.

Can you copy an image generated by Probability Calculator to the clipboard to paste into a word processing document. Or maybe to generate, say, a png?

When I open version 3.2 or 4.0 of GeoGebra the default on my computer is a window with the axes and grid showing and the horizontal axes is in multiples of pi.
I noticed that the windows given by the presenters do not include the grid, nor the x-tickmarks in terms of pi. Is there a way I can change this default "look" that automatically comes up upon opening a new file?

I would like to know how to input parameter values without using a slider, e.g. by typing.

Can the function inspector table be exported other than as a screen capture?

Mathmagic replied:

hello
i select the table of points in function inspector, then control+c then in spreadsheet (or in excel,word etc) control+v so i create the list of points

is that you want?

Is it possible to turn an webpage back to a ggb file provided that the webpage was created with Geogebra?

I don't yet understand how to use TextField for input. I made a text box with script m = %0. I wanted to use m as a parameter for a function, f(x) = m sin(x). Typing that in the input field, however, gave an error message that m was an undefined variable.

Thanks, Tony. I was about to ask the same question. I got Mike's slope field ggb just now this way.

Is there any reason you can't use the spreadsheet in 4.0 Beta to calculate the size you want the graphics window to be, then enter those variables for the x and y window sizes? I did this last night, seemed to work great but.. 4.0Beta has gone south and seems unrecoverable. I've done everything to get it back.. reboots, uninstall everything, reinstall, 4.0 starts to come up, shows a blank spreadsheet, and disappears.

How do you make a drop down menu (of functions, say)? I am creating a file on limits and would like to investigate limits for a few different functions.

Request: Some instructions on creating Linear Algebra applets - perhaps related to matrices and transformations. Thank you.

I'd like to be able to move (translate or rotate, for example) a polygon as a "continuous" motion, rather than a jump to the final position. Or, rather, I would like to display such motion on an applet. (GSP has such a feature, though I can't remember how it works.)

I have added some GG5 files to my personal folder under Auston Cron. If you are interested in GG5 you are welcome to view and borrow.

As promised, I have a lot of questions. Here are some of them (and I'm working in 3.2 because I can't get 4.0 to work properly):

1) I can't find/remember how to change the x axis to be in terms of pi/2 instead of integer values.
2) I want to graph a function with a restricted domain...how do I do that?

Often in Text displays we have formulas involving (x-h) or (y-k) which looks ok when h, k are positive. When they are negative they look ugly (x--h) or (y--k), and while you can kinda defend it, my personal preference is for it to display as (x+h) etc. I've include a snippet of code showing how I address this in my applet folder, but if anyone has simpler code I would appreciate it.

Will we learn how to create our own buttons.

I'm working on completing my applet. I can't get the GeoGebra tools to show up when I open the htlm file. I have gone into the source and changed the height and width, but I still cannot get them to appear.

I created a check box for a function f(x) and selected/hid objects used in the construction of my applet. Now, I would like to go back to hide other objects related to the f(x) check box. I can't seem to get to that same screen upon CNTRL-CLICK of the check box - I just get the Object Properties window. How to get back to list of items to hide?

On using CAS in the classroom, I have been considering showing Algebra I students the steps needed to solve equations using the properties of equality. CAS commands listed here http://www.geogebra.org/trac/wiki/GeoGebraCAS/Documentation

3x + 5 = 7
(3x + 5 = 7) - 5
(3x = 2)/3
x = 2 / 3

This will re-enforce what is taught in the classroom.

Equations
Equations are written using the simple Equals sign, e.g. 3x + 5 = 7
You can perform arithmetic operations on equations, e.g. (3x + 5 = 7) - 5 subtracts 5 from both sides of the equation. This is useful for manual equation solving.
LeftSide[3x + 5 = 7] gives 3x+5 and RightSide[3x + 5 = 7] gives 7

With these students, do not use advanced methods in CAS.

Question for Group 1: In the FunctionsasIntegral applet, how did you make the Clear Traces check box actually clear the traces? I can create the check box - it is not doing what I would like it to do. Thank you.

I think someone mentioned it is possible to create new tools. I'd like to see an example.

Great site for Euclidean Geometry is Linda F-S site Ruler and Compass at http://geogebrawiki.pbworks.com/w/page/10994355/Compass-and-Straightedge

Setup is ready for most Euclidean work.

Anyone familiar with LimitAbove and LimitBelow commands? They are giving me the same value at a jump.

I posted a 4.0 update of a file on my applet page. I would like to allow the user to see either tangents to curves XOR secants to curves, but not both, or to see neither. I'd really like something that works like radio buttons. Any ideas? TIA.

I'm trying to put together an applet where the student can click a button and it will display a graph randomly, from a list of 15 or so different functions that I provide. Something similar to the "reset the graph" button at http://webspace.ship.edu/msrenault/GeoGebraCalculus/derivative_try_to_graph.html What's the best way to do this?

Also, is there documentation anywhere on exporting an applet using HTML5 so that it will run on an iPad? Whenever I try, the toolbar disappears.

Is there a way to erase everything done with the pen tool with one button or checkbox? Basically, what I want to do is be able to draw something with the pen -- possibly with a few separate pieces -- and then erase all the pen work and draw something else. The only way I've figured out is to use the arrow to select a rectangle to draw in, then draw there, creating an image, and then delete that whole image when I don't want to see the pen marks anymore, but I'm trying to figure out if there's a way to do it without having to redraw the box each time.

Actually, now that I think about it, one way might be to have a single button that's scripted to delete the current pic and select a new box to start the next drawing, but I'm not sure how to do that. I think I need to learn some more about scripting to get this to work right.
