Hello All,

(I also sent this fact to Maplesoft Support).

Since I updayed to 2016.1 the F1 key does bring a menu witch send to..F5 only.

No way to have a "full" Help Menu.(See the attached file)

I guess a silly bug jumped in :)

Kind regards,

I have a maple homework on the collatz conjecture, but i am new to maple and does not know how to program it.

our professor gave us the first part, i tried a lot of different loop, but keep getting errors. Need HELP.

I need to test all integer m <= 60, i dont know how to set up a loop that can test all 60 numbers.

### Displacement in elasticity...

Hi

I've this equation ,what is displacement,

U := sum(C[i]*lambda[i]*h^2*M*(C[13]+C[55])*exp(Z*lambda[i]*M)*cos(M*x)/C[11], i = 1 .. 4);
But when I used the data ,I do not get the right result

the datas are

h := .25;
M := Pi/L; L := 1;
E[3] := 1; E[1] := 40; E[2] := 1;
1
V[13] := .25; V[31] := .25; V[12] := .25; V[23] := .25; V[32] := .25; V[21] := .25;

G[44] := .2; G[55] := .2; G[66] := .2;

G[13] := .5;

C[55] := G[13];

Omega := -2*V[13]*V[21]*V[32]-V[12]*V[21]-V[13]*V[31]-V[23]*V[32]+1;

C[11] := (-V[23]*V[32]+1)*E[1]/Omega;

C[12] := (V[13]*V[32]+V[12])*E[2]/Omega;

C[33] := (1-V[12]*V[12])*E[3]/Omega;

C[1] := -.2596702449; C[2] := -2.411545729; C[3] := -0.6051254981e-1; C[4] := .4085627399;

lambda[1] := .6891428810; lambda[2] := -.6891428810; lambda[3] := 9.177422410; lambda[4] := -9.177422410;

could you help me plase

### DirectSearch Help migration into M2015...

October 30 2015

So I installed copied DirectSearch.hdp and DirectSearch.mla into my Maple2015\lib directory and the program works (all the functions are there) but I cant get help menu by querying ?DirectSearch.

I'm running win7 64bit btw

so under

?hdb

i put this into maple:

HelpTools:-Database:-ConvertAll();

but i get error....

"Converting C:\\Program Files\\Maple 2015\\lib\\DirectSearch.hdb to C:\\Program Files\\Maple 2015\\lib\\DirectSearch.help"
Warning, .hdb help databases are deprecated, 'C:\Program Files\Maple 2015\lib\DirectSearch.hdb' will not be used, see ?HelpTools,Migrate help page for more information
Error, (in HelpTools:-HelpCallUI) cannot create help database: 'unable to open database file'

any clue?

ps I asked the same question for M18 but I managed to get the help to work in that instance.

http://www.mapleprimes.com/questions/204423-Help-Build-For-GlobalSearch-Package

(i also copied DirectSearch.hdp and DirectSearch.mla to Maple2015\bin.X86_64_WINDOWS directory but no joy, there is no .help file created in either bin or lib directories)

### Is there any use of the specific 1-D math input ot...

September 29 2015

Hello those in mapleprimes,

I have a question.

I opened Help and entered diff, for example, to have the explanation of how to use diff.

Whether it is diff or not, is not the problem I want to ask about now. But, what I want to ask is the following.

I cklicked the WS botton at the tool bar of the Help, so that I created the worksheet of the same contents of the help of the diff.

Then, I chose an expression in Calling Sequence. That is,

the first line shows

diff(f,x1, ..., xj)     on the left, and on the right \frac{d^j}{dx_j \cdots dx_I} f (I wrote this in the TeX ways, though

it is written in 2-D math input, actually)

I chose an expression on the right side, and from context menu, which appeared though right clicking of my mouse,

I selected convert to and 1-D math input, through which I changed 2-D math of the worksheet of the help file to 1-D math input.

Then, the expression shown is a strange one:

((&DifferentialD;)^j)/(&DifferentialD;x[j] ... &DifferentialD;x[1]) f;

This is still easier one. As for the third line in the Help, it has a more complicated form as

((&DifferentialD;)^r)/(&DifferentialD;x[k]^m &DifferentialD;x[j] ... &DifferentialD;x[3] &DifferentialD;x[2]^n &DifferentialD;x[1]^n) f;

Do you know how this way to notate is applied in maple worksheet?

Why does maplesoft use this way to notate expressions limited to the Help pages, if it is limited to the help pages.

### Cannot find the help-manual menu of maple2015...

### why do Maple help pages look so...?...

I started to notice strange things happening to Maple help pages lately when I google something. I think someone is changing them from inside Maplesoft? Now they look hard to read since I see text below another text and also can't copy it to retype it in my notebook since the syntax is not even valid. Here is a screen shot

http://www.maplesoft.com/support/help/maple/view.aspx?path=FileTools%2fText%2fOpen

I thought at first my browser was playing games on me. But I tried it with firefox and Chrome and after refreshing, and the pages still look mangled like the above.

Since I find it hard to believe someone at Maplesoft will make help pages like the above on purpose, where text falls below the line and it not even possible to interpret it when one wants to copy it, since the syntax is not even valid Maple syntax, I would have to imagine there is a bug somewhere inthe help pages generation.  But if so, someone must have seen it before me. I can't be the only person in the world who is googling Maple help.

This is why I am asking.

Is everyone seeing the same thing I am seeing? I am on windows 7, using Latest browsers.

It looks like the Online Help has now been updated for Maple 2015.

Here's the What's New in Maple 2015 Overview, which is similar to the product pages currently available here.

But we can now also link to and view the online versions of full help pages of new or enhanced commands or example worksheets. For example, dataplot.
