Mathcad

Dear all I have a problem when open a worksheet in mathcad prime 3. When I try calculus appear "Mathcad has stopped working". Before, the program worked well. Please some ideas. Thanks, Luis.

One of my students thinks he's found where PTC offers Prime 3.1 to students without expiring in 30 days.  As far as I know, he's talking about Express.  He says it still works, more than 30 days after being downloaded, but I think he's misunderstanding.Does PTC offer any kind of download for college students other than Express?  I was able to generate some enthusiasm today in class with an impromptu Mathcad demonstration.  They even asked for an additional Mathcad help session outside of class and asked where they could download it, but the interest waned when I told them they would have to pay for it after 30 days.  The same old problem.

   Hello Everyone,  How to solve [e^x*1i]^1i = e^pi ?      Thanks in advance for your time and help.           Regards.

Hello all,I have a matrix of vectors. I plotted one of the vectors below. Can someone tell me the "proper" or most elegant way of calculating the mean of the values?I have a mild flu and it's hard for me to concentrate, so I thought someone could nudge me along TIA

Hello,I 'm trying to integrate MathcadPrime 3.1 in SolidWorks2017 with registering a dll-File using the "RegAsm.exe" command in the Windows PowerShell but I got following error message:PS C:\Windows\Microsoft.NET\Framework64\v4.0.30319> RegAsm.exe C:\mathcad\mathcadprime.dll/codebaseRegAsm.exe : Die Benennung "RegAsm.exe" wurde nicht als Name eines Cmdlet, einer Funktion, einer Skriptdatei oder einesausführbaren Programms erkannt.

I'm under the impression, perhaps false, that there are many published ebooks on the PTC website. Can't find them. Where are they?

My assignment requires me to use genfit to fit this plot. However, it keeps saying that the variable "y" needs to be defined as a vector of real numbers, which it is. Not sure why it keeps saying this error and I do not know what to do. Any suggestions? I believe it may be a issue with the software.

Hallo liebe Community,ich versuche mich an  der Programmierung eines Tools für meine Masterarbeit.Dabei ist die grobe Idee, einen Pfahl im Boden durch  dynamische Bodenschwingung anzuregen. Der Boden wird über eine gedämpfte harmonische Funktion in  Schwingung versetzt, es ergibt sich als Eingangsgröße ein Matrix(i-Knoten des Pfahls in der Tiefe, j-Zeitschritte).Diese ist wiederum mit der Differentialgleichung des Balkens verknüpft.Mein Ansatz ist eine differentielle Form.Leider bin ich etwas überfordert mit der Syntax, da ich Mathcadfrischling bin.Mein Hauptprogramm(Unterpunkt 6) schreibt mir immer wieder Fehler im Bereich der Zuweisung heraus, vll kann mich ja jemand mal unterstützen.Gruß Peter

Please check the sheet attached.If I use the max-function on a matrix filled with strings, it returns a result.If I use the same function on a column of the matrix, it gives an error ("These values must all be of one type")If I assign the column of the matrix to a new variable, but don't evaluate and then use the max function on the new variable it errorsIf I assign the column to a new variable and evaluate, then use the max function, it gives a resultIf I write a little program and search the max of a column with different values, it errors but in the same program, if I search the max of a column (transpose of a row in this case) with identical values, it doesn't error.Can anybody explain this inconsistent behaviour?

   Hello Everyone.{ [1i + tan(pi/2)] / [1i - tan(pi/2)] }^1i = 23.140692632779 or not ?      Thanks in advance.             Regards.

A dozen years ago,  Mathsoft.com (see Waybackmacine) listed a section of mathcad-related books. I counted around 40+, around half or more in the last 5 years (2000-05).I recall, distinctly, that there were at that time many websites with mathcad tutorials, showing and offering .mcd files to download and learn. Calculus, differential equations, economics  had their mathcad experts that offered plenty of inspiring work.Now there is very little left, and that little is often just a fraction of the material that was created and made available more than ten years ago. So the landscape nowadays looks very different, unfortunately. I hardly recall 1 book about mathcad (Prime or not), in the last five years or so. I came across recently with the resources of one of the most popular authors of math textbooks (ronlarson.com). He makes available resources and files for mathematica, maple, matlab. But nothing about mathcad, even if  it seems a much better tool for  tutorial pur

I change s to hhmmss unit of time and get an error

I tend to forget a lot of things, so I don't remember if this bug is already known and was reported and discussed here.Anyway, Mathcads symbolics gives a wrong solution for a simple equation:but if we use "fully", we get the correct solution, as any value from -1 down is a valid solution:And also if we replace the square and square root by an absolute value, Mathcads answer is OK:EDIT: Just noticed:MuPad knows thatand so we get at least no wrong results if we simplify before we solveNevertheless, returning a numerical wrong result in the first place is an absolute no-go in my opinion.RegardsWerner

Im after any example of dtaa poeple have used and entered into MAthcad for normal ditsirbution calcs

‌habe die kostenlose Version mathcad Prime 3.0. jedoch kann ich im Menü Ein-und-Ausgabe nicht konvertieren. Das Feld ist nicht "klickbar".

There is a good chance I am just being less than intelligent about this but I'm having some trouble calculating the energy required to heat a container of air (a hot air balloon).In this scenario, the pressure is remaining constant and air just leaves the container as temperature increases and air expands (in other words mass is decreasing). Since Q=m*ΔT*Cp it should take less energy to heat the decreasing mass then it would to the system if the mass was constant however my calculations are saying otherwise. I know I'm doing something wrong but I'm just not sure what. Thanks

Hi,Can someone help me to find solution for equations which have specific values. I try determinate model for logged signal that. Please see more attached file.Thanks in advanceMika

  Hello, Everyone.  From :  How to solve sin(e^{atan(1i*[1-x^2i]/[1+x^2i])}) - 1 = 0 ?       Thanks in advance.             Regards.

Hello all,Below is a snapshot of an illustration of something I'm trying to do.  .xmcd file is attached.TIA

It will be good to have

I a file with steps on mathcad so that I can learn how do it with other problems, i am new in mathcad. thank you guys

Hi,I know it is possible to control the unit of the result in an equation. Is this possible as well within the equation itself or do I have to put in a correction value instead?E.g. I am doing some calculations where the defined variable in the equation must be entered as rpm where as the variable is calculated as rad/s, which is the SI unit.Thanks in advance,Ronnie.

Hello again,I got some help a while back from here regarding turning a nested array into a single array.  Now I have a similar problem in that I need to turn nested matrices into a vector of 3 single matrices.  I've tried modifying the code for the arrays but so far unsuccessfully.  If anyone can help with this I would be very grateful.Thanks,Mike
