Thanks, yes that gives me what I want.  Does maple have a global option in the tools menu to set the number of decimal places after the decimal point?  Be a nice little addition if it doesn't. 

Some numbers won't display more digits.

Specified numbers in the numerator won't display more digits.  evalf(10.5,10) displays 10.5.  The only way to force maple to display more digits is to divide by 1.0 evalf(10.5/1.0,10) displays 10.50000000

Now if I want maple to only display 2 places after the decimal, specifying the number of digits won't work which brings me back to my original question in this thread. 

Okay I'll try to clear up what I mean.  What I want, is not to display it's current value but to display the expression with it's variables only.   

So if d=a*b+5/(3*h) and I've assigned values to a,b and h.  How do I get maple to display the original expression for d after the variables have been assigned?

Yes, thanks for the explanations.  It clears things up a lot except that glitch between the points -7 and -8 it's quite a huge jump and it does bug me.  Similar with the positive axis.  If I didn't know better to include a numpoints option and I was to hand that graph in to be marked I'd get zero. 

Maple should draw the graph without those jumps.  I think it's a glitch in the maple graph drawing that need to be fixed.

Okay that works a better.

The default for numpoints is 50 however I get different graphs with and without using numpoints. 

plot(cos(2*x^2),x)  graph shows the problems I initially had but when I explicitly use numoints=50 plot(cos(2*x^2),x,numpoints=50) ,the default, I get a nice graph no erroneous or wayward lines. 

Maybe the default maple states on the help page for numpoints being 50 is not actually 50.  Regardless wether I state it explicitly or not I should get the same graph result.  Should I not?

How do you add more lines in the vectorfield plot?  I followed this post then followed lemelinm's link and found that that graph drew a minimum number of lines.  The maple help on this ironically wasn't very helpful.  How do you get more lines in there using verctorfield?

I thought about changing the theme in windows but I didn't want everything changed.  Another nice work around trick though, thanks.

About changing the background in the classic interface, I couldn't find that option in any menu.  Do I have to modify the maple.ini file?

Thanks.  I want to be able to change it to a corn husk color - same as the help pages, much easier on the eyes as you said.  Or maybe to fancy it up a little, in any case I'd like to have the option available. 

BTW, that table tip is a nice little work around, thanks. 

I wonder if the option was too much hastle for Maple to bother with.  At least we know they're mostly focussing on the maple engine rather than fluffing it up with too much extras and eye candy. 

Thanks for the tips.  Maybe in a future release they'll have that option?  Maple 13?  Based on past release dates I suspect Maple13 will be released around the June/July timeframe.  Looks like a major issue change so it wouldn't be included in an update.

Also sorry for the multiple posts, I had a connection issue.  Can someone delete those posts?  Or can we the editor delete our own posts? 

I've taken the liberty to find out how it works so I hope this helps...

First create a directory where you want your database to be stored (ie. c:\Program Files\Maple 12\AddedHelpFiles)

Now in order for maple to use it and read it everytime you start maple instead of having to invoke it using the libname command for each session you want to access your help file, create a Maple.ini file in your c:\Program Files\Maple12 directory using notepad and include the line (for our example)     libname:=`c:/ProgramFiles/Maple12/AddedHelpFiles`,libname:      the colon will supress the output when maple loads and your new directory and help pages will be included in your following new maple sessions.  Note: be careful of the direction of the slashes, using the other slashes will give you an error.

Next open a worksheet and create a page you want added to the help database.  Then go to Tools->Help Database-> Save as help page.

Under select Writeable database enter your newly created directory c:\ProgramFiles\Maple12/AddedHelpFiles\Maple.hdb (You can call you help database file whatever you wish, I've just named it Maple.hdb for convenience) Also note the direction of the slashes, again I cannot tell you why but that's the way maple shows them in it's list of writeable database files so I've just followed the same convention.

Under Topic, enter the searchable name you want.  We'll call it, Helptopic.  So whenever you search, it will pull up your help page.  Also note to keep this name the same as the name you will put for your table of contents name or you will never be able to remove it from your database when they differ if you forget. 

Now the tricky part is that the Table of Contents entry is optional, unfortunately if you don't enter anything here you will have much difficulty if at all finding your page while browsing the help database except by using ?Helptopic to find it.  Your help page will be put somewhere by Maple in which I have had no luck in finding. 

For our example we'll enter the same as we put for our Topic entry, Helptopic.  So this help page will now be put in the help page under the name we entered here.  However most people likely will probably want the pages to be under a subdirectory name.  To do this you must enter a slash "/" after the name in the directory you want but don't forget to name the help page for the table of contents or it will be nameless.  So for our example we'll type in Helptopic/Helptopic and our help page will now be named Helptopic under the directory name Helptopic searchable by the name Helptopic from our entry we put in for the Topic field.  Confusing, eh?

Well we're done.  Then we just click okay and a box pops up The worksheet may contain features which are not compatible with the chosen format.  Continue?  Just ignore and click okay and the next box that pops up is The database c:\ProgramFiles\Maple12/AddedHelpFilesMaple.hdb does not exist.  Do you want to create it?  Just click yes.  And there you go. 

There's a bug where there's a missing slash in the pop-up box but it's not critical. 

Close maple and restart or invoke the libname command in your current maple session in order to use your maple help pages. 

I'm getting so frustrated.  It seems I am the only one having trouble creating help pages.

There is no example on how to create a help page.  I've read the addhelp in the maple help page again and again and I'm still having trouble.

I'm trying to create a help page named PhysicsEquations under a folder named UserCreatedPages in the maple help table of contents.  This is what I have done.

I've created a directory c:/Program Files/Maple 12/Userlibrary

Then I've added a maple.ini file in the C:/Program Files/Maple 12 directory with the contents   libname:=`c:\Program Files\Maple 12\Userlibrary`,libname:

Next I go and open a new document mode worksheet and enter a title and a few equations  etc...

Then I go to Tools -- > Help Database -- > Save as help page...

Select writeable database - Then I see a list of files c:\program files\maple 12/lib\maple.hdb  etc... but I have no idea why there's backwards and forward slashes and no indication in the help files why it is like that. 

So at this point I type in the directory location c:\program files\maple 12\Userlibrary for the writeable database

Topic: PhysicsEquations

Aliases: I leave this one blank

Table of Contents: UserCreatedPages

Click on okay then close Maple, open it up and look in the help pages and nothing.  There's no entry in the table of contents for my created help page. 

Can someone please tell me what I'm doing wrong and what I'm missing?

Maples response was that there is currently no way to get it into the menu bar.  This was communicated to the developers and has been submitted as a request to be put into future versions. 

I kind of wondered why there was a toolbox folder where add-ons went in to, and yet there was no menu bar with a toolbox option.  Maybe that's what they will come up with in a future version. 

Maybe also they can come up with an option in the options menu to toggle on and off the triangles at the side of a document, unless by turning them off it infringes on other document writing software patents.
