Regneark med databehandling af grupperede observationer bør have flere betydende cifre i Frekvens og Kum.frekv. (kolonne D og E), samt felterne Observation og Fraktil (celler F9:G10).
Resultater bør som udgangspunkt ikke være uden decimaler. Afrunding bør ske af brugeren.

In the following example I get the wrong result because I added a space betwen f and (0).

f(x):=2*x+1
f (0) = 0      // Note the space between f and (0)
f  (x) =f*x    // The problem is that wordmat interprets space as a multiplication

Ideally wordmat should discover that f has previously been defined to be a function, and therefore the space does not mean multiplication.

It says that MikeTex is not installed when I already have it. And also, this happens with other programms like Geogebra, Graph, etc.

Konklusionen i binomialtest regnearket er "0-hypotese bekræftet. Det kan ikke afvises at den observerede middelværdi: 79 er korrekt." Det er vel ikke en middelværdi, man observeret, ej heller kan den være forkert eller korrekt.
Tegnet "my" anvendes som symbol for den observerede værdi. Det er heller ikke standard notation.

Hi Michael

Here is an other one. Wordmat freezes if I write spaces between "\partial/\partial x" and "f(x,y)". It more or less looks like this, but look at the attached example file

f(x,y):=x^2+y^2
\partial/\partial x f(x,y)      //this works
\partial/\partial x     f(x,y)  //This causes wordmat to freeze

Kind regards

jeg har akut problemer med at word ikke kan beregne noget. for en Error Code 2: wordmat kan ikke starte maximus med det samme når jeg prøver at beregne noget selv 2+2..

windows 10 Pro 64 bit

nogle der kender til denne fejl? jeg har prøvet at hente flere versioner

I am sorry to spam you with issues, but here is another one

f(x)=x^2         // Note that I did not write :=
f'(2)                // wordmat freezes when I press alt-b here

Note that the function has not been defined, so wordmat cannot calculate f'(2), but ideally wordmat should not freeze

If I change the "=" in the first equation to ":=" then I get f'(2)=4 as expected

Hej, jeg oplever at mit wordmat ikke virker og Word giver mig beskeden på billedet herunder.

Efter beskeden er poppet op og lukket 3 gange, kommer jeg ind på word, hvor at wordmat så ikke virker. Trykker man på wordmat folderen bliver man spammet med samme besked, som man skal nedkæmpe for at kunne bruge word.
Selvom man sænker sikkerhedsniveuat til alle makroer har adgang, virker det stadig ikke. Eller hvis man geninstallere wordmat og word, hjælper det heller ikke.
Det har virket on and off længe, og opført sig efter hvilken word fil man har åbnet, men nu nægter det at samarbejde.

Er der andre der oplever det samme, og er der en løsning på dette?

I excel-arket med binominalfordeling under fanen Binominaltest giver konfidensintervallet ved nogle n og p værdier resultatet "#VÆRDI!". Når man viser beregningstrin, kan man se at det kommer af "Error: Numerator Not A Whole Number" ved beregningen "C2 * C3", altså n * p, inde i både binomlow og binomhigh. Ved at ændre "C3 * C2" til "AFRUND(C3 * C2; 0)" kommer der et konfidensinterval ved alle værdier af p og n. I sagens natur er det konfidensinterval, man får med denne modificering, dog en smule forkert, når n * p ikke giver et heltal.

Jeg tænker, at den optimale løsning ville være en ændring i binomlow og binomhigh, så de også kan arbejde med decimaltal. Jeg ved ikke hvor vanskelig den ændring er, men hvis det er for svært eller tidskrævende, tænker jeg, at man kan tilføje en afrunding, så der altid returneres et konfidensinterval, selvom det ikke er helt præcist.

Hvis det er brugbart er det i Windows 10 i WordMat 1.22.

Given an equation of the form
x = expression
where x is free in expression, students ought to click "evaluate",
but often they (to much chagrin of the teacher) click "solve equation".

Since it is easy to determine whether an expression is free of the variable
to solve for, I suggest that solving such an equation automatically
switches to "evaluate" (or perhaps prompts the student).

Example:

Solving x=1+2 currently leads to this output:

x=1+2 
        solved by Wordmat
x=2

I suggest the following output instead:

x=1+2 ~ 3

Efter genstart af min Windows PC fik jeg nedenstående fejlmeddelelse. Den forsvandt med 3 klik på "OK", men der er intet WordMat længere i Word. Hvis jeg klikker på WordMat fanen fremkommer samme meddelelse, men den lader sig ikke lukke.
WordMat er aktivt som tilføjelsesprogram, men det virker ikke.

I've tried with 4 different Office 365 installations. Tried with version 16.43(20110804), 16.44(20121301), 16.45(21011103) and also 16.46(21021202) - and it seems all software versions are not accepting WordMat.

WordMat is reporting "error" during calculations, and after several error messages, WordMat is aborting.

I'm using the latest Mac M1 architecture as MacBook Pro M1 and Mac Mini M1, both with the same result, which may not have support for WordMat.

When do you have the next version of WordMat available?
Does this version have support for M1?

Beregning af konfidensinterval i binomialtest.xlsx er ikke korrekt.
Funktionerne binomlow og binomhigh anvender forventet p-værdi til beregning af antal successer.
Det bør være observeret p-værdi, således at antal successer bliver et helt tal.
Alternativ skal antal successer indtastes, og observeret p-værdi beregnes.

Altså i celle J20:

• binomlow(C2*C3; ...
  rettes til
• binomlow(C2*C4; ...

Tilsvarende for binomhigh.

Hi

When I try to install Wordmat on Word from Office 365 version 2101 I get an error message saying that only version xxxx is supported.

WordMat til M1-Mac kan ikke give eksakte resultater (hverken ved beregning eller ligningsløsning), uagtet om den er sat til eksakt.

Her er et dokument hvor wordmat svarer at

Når jeg forsøger at konvertere til disse formater, det siger, at jeg ikke har MikTex installeret, når jeg rent faktisk gør. Er der nogen anden måde at konvertere det? Eller hvad skal jeg gøre?
Tak

First of all: @Eduap-com, huge applause and thanks for the M1 update!

Preparing for my math class I stumbled upon a bug when solving 2 equations with 2 unknown.

I get [x,y] ∈ Ø.

Hi Michael

I have some problems with using comma as argument separator when calculating partial derivatives of functions of two variables in wordmat. Here is an example

f(x,y):=x^2+y^2
f_x'(x, y) = 2*x
f_x'(2, 3) = 4,6   // I had expected either 2*2=4 or an error

Hej,

Jeg har kigget lidt på listen af Issues, men kan ikke se at @Eduap-com
har kommenteret - så nu er jeg kommet i tvivl om beskederne bliver læst.
Er der måske et problem med spam-filter eller lignende?

Here is a file that can cause wordmat to freeze if I press ctrl-B the wrong place.

freeze_when_calculating_derivative.docx

If I press ctrl-B in an equation containing a derivative f'(x) then word will sometimes rewrite the equation to place '(x) in the exponent. This can lead to an equation that wordmat cannot parse.

Kan det passe at wordmat tilføjer funktiioner til geogebra?

Hvis ja, så ville det være rart at tilføje en funktion ved navn "kvadratrod"

Min elever har svært ved at huske at de skal skrive sqrt(x)

WordMat til M1-Mac vil ikke løse vedhæftede ligning for den ukendte øvre grænse i integralet. WordMat til Intel-Mac kunne godt løse ligningen korrekt (testet på flere M1 og Intel Macs, alle M1'erne skrev, at ligningen ikke har løsninger).

When your are working in fullscreen on Mac (green button top-left corner), and then calculate a gray box appears in the middle of the screen. It goes away if you leave fullscreen mode (green button top-left corner). It can be seen below, but be aware it's a little hard to spot on the screenshot...

I have a MacBook Pro from 2018 with the Intel chipset, and my Word just crashes whenever trying to calculate an expression. I read in the FAQ that this version isn't supported yet, but I would like to know when a possible release date is due?

Have tried all morning to install Wordmat

• win10 64bit

• office 2016 64 bit

• Anti virus has been deactivated during install

• Porgram has been run as administrator

Wordmat is shown in Word and I can write functions but as soon as I click Calculate (Beregn) it crashes saying that Wordmat was not installed correct

Example: typing f'(2) and pressing alt+b when f is not defined, causes word to crash.

Wordmat version: 1.22
Platform: Windows 10 2004
Wordmat crash.docx

Min wordmat kan ikke udregne eksakte resultater selvom jeg har indstillet den til det. jeg har linket et billede som eksempel på det.

WordMat doesn't work on the new MacOS Monterey version. When I try to do any calculation, Word freezes and the ram usage explodes. Word is also stuck at 100% CPU usage. Seems like it's the "sbcl" process that causes this, which i believe is Maxima. It also seems like the Maxima version included in WordMat is from 2016 :/
Hopefully this is an easy fix, so I can get back to using this tool at school :)

Hello there,
I'm using the command "insert numbered equation for reference" with a numbering type as (1.5). The obtained reference is: "Equation 1".
How may I have "Equation 1.5"?

Thanks

Residualer og residualspredning ved excel-regression er forkerte, de bliver alt for store:
Eksponentiel regression fejl.xlsx

Wordmatversion: 122

I think that there is a small mistake in the formula for confidence interval for p in the binomial test excel sheet

I assume that

• "forventet p" (cell C3) is the value of p that is mentioned in the null hypothesis (H: p=p0)
• "observed p" (cell C4) is estimated from the number of succeses in the sample ( \hat p = r/N)

If that is true then I think that you should use \hat p = r/N (cell C4) to when calculating the confidence interval for p. The idea is that you use the number of observed successes in the sample to construct a confidence interval. Once this interval is constructed, then you can test a null hypothesis H0:´p=p0, by examining if po is contained in the confidence interval. In other words the confidence interval is independent of constant p0 from the null hupothesis, Here is a video.

https://www.youtube.com/watch?v=-2KRNFk8oEA

I realize that wordmat is also doing a meaningful calculation, but I don't think that it is consistent with formula for "confidence interval for p" in the official curriculum.

It is probably not a good idea to change this shortly before the exams that may or may not take place this summer....

PS: The observed number of successes use usually called r or \hat x. \mu usually denotes the true mean. (Edited)

So as my title says, wordmat got identified as a trojan horse, what should I do about this?
Here's the link to the screenshot: https://imgur.com/a/5SAU4ae

Hello
I am using windows. My school got office. Lately i deleted everything from my computer and starting reinstalling everythingg. When i downloaded Office, I got the usual, word, excel, powerpoint and so on. But when I installed wordmat, an error appeared. You can see it in the attached files. It translates to "You haven't installed Excel 2007, 2010, 2013 or 2016. Installation canceled. I've got Excel downloaded, and it works fine. I have even installed older versions of Wordmat, and also reinstalled the Office several times. I keep getting this error. Hope I can get some help :)

Wordmat har et problem med at udregne bestemte integraler hvor den nedre grænse er skrevet som en potens. Der opstår en fejl i programmet når man prøver at skrive
\int^{y^2}_{y^3} 1 dx
Men den kan fint udregne integralet hvis man i stedet skriver
\int^{y^2}_{y*y*y} 1 dx
Selv noget simpelt som
\int^{3}_{2^2} 1 dx
kan den heller ikke udregne, men den kan sagtens udregne det hvis man skriver 2*2 i stedet for

Chromebooks are perfect computers for students... Except for the lack of wordmat

Use https instead of http in order to avoid the "Not secure" label in Chrome.
As a bonus, I believe a switch to https also leads to better ranking in a Google search.

Big issue for schools

Jeg hjælper en elev, hvis MacBook (med Catalina) ikke vil udregne resultatet korrekt.
Vi har både tjekket i Maple 2020 og med mit eget WordMat, og ved de to bliver den udregnet korrekt.

Kender nogen en løsning? Geninstallation af Office og WordMat er forsøgt.

Jeg er vedhæftet hendes gemte dokument med ligningen i.

ligning.docx

If I use \sqrt to write a square root in wordmat and try to copy it using ctrl-c, then wordmat freezes. This is what I write to create an "uncopyable equatiion".

<alt-m> \sqrt <space> (13) <alt-B>

I don't know if this is really a wordmat error, because I can sometimes reproduce the error if I uninstall wordmat and load the document again

• Create a document with an "uncopyable formula"
• Save the document
• Uninstall wordmat
• Load the document
• Try to copy the formula
• Freeze

Note that if I use the menu to create square-roots then I don't get a freeze, so I wonder if wordmat somehow adds a special character trat causes problems. Here is an example file

sqrt_causes_freeze_when_copying_text.docx

At some point when working with the document I got an asd-file and I think that I got a message that the document was damaged. I don't completely remember the details, but I attached the asd-file

~WRA0000.asd.docx

Here is an idea. It could great to have a menu item (or hotkey) to simply an expression numerically.

Right now the students can achieve the same by choosing

• ctrl-N choose numerical
• ctrl- B
• ctrl-N choose automatic again

This solution works, but sometimes students forget to switch back to "automatic", and this causes problems in later calculations. I think that my idea might be easier to teach.

Here is an example where wordmat interprets 1/3(-2)^3 as (-2/3)^3, but the student meant to write 1/3*(-2)^3
