Mathcad

Hello everyone! I tried to write something of quantum mechanics with Mathcad . A limited MQ vademecum came out (see pdf attached). What do you think about it?

Hi, This is regrading computation difficulty, There are three variables which are matrices consisting of ten values each, To find out the resultant current all the combination of values ( three variables) must be considered and using resultant matrix we can plot the graph. example: For each value of Ubat combination of RX and RY must be considered. Please find the attached file for reference and kindly do the needful.

Hi all,   I am brushing off cobwebs after not using Mathcad since last spring and I can't figure out why what I've got isn't working.   I've attached my sheet; basically, I'm trying to use the finite element method to find a stiffness matrix over a length L, where the area is changing from 0 < x < L/4. I need to make a 3x3 matrix involving an area equation (which I've called A1 in my sheet), shape functions (psi), and the material stiffness E (which would just be a variable carried through until the end).   I've read through a couple of other forums and I haven't been able to apply any of this to my particular problem (whatever it is).   Is there something I'm overlooking?

Hi all! Is it just me or do you experience the same bug. I am using the current Mathcad 15 M050 and have just noticed that filterNaN and matchNaN do not work anymore! The error message is something about "The type initializer for Efi.Data caused an exception". I am pretty sure that I had used filterNaN with this version of Mathcad without any problems. Can it have something to do with the fact that I recently installed Prime 6? Or is one of the recent Win10 updates the cause? Here in the forum I just found this https://community.ptc.com/t5/PTC-Mathcad/New-bugs-in-Mathcad-15-M020/m-p/380775 where somebody reported that the error occurred immediately after the installation of Mathcad.    

Hello! My name is Ivan and I often use Mathcad 15 at my university. I've been working on some task recently which involved symbolical calculations in Mathcad. I faced a problem that one of the integrals just won't solve. I used Mathcad for over a year now and i have no clue how to fix this. Can someone tell me what's wrong? Thank you in advance!

I don't know how many are aware of this, so I'm posting some important information.   Starting January 1st next year (2018) PTC will make it's products available by subscription only. https://www.ptc.com/en/news/2017/ptc-accelerates-subscription-business-model Basically, legal ransomware. If you don't keep paying them, you will be denied access to your own IP.   My understanding is that this new scheme will apply to all PTC products, other than one obscure product, so that includes Mathcad. I believe that existing perpetual licenses will continue to be perpetual (hard to see how it could be anything else, since that's how they were sold), but going foward you will either have to pay every year, or lose access to your own work.

Hi, Our issue is that some of our Mathcad Prime sheets stops being able to calculate – especially when we are using the program for calculating Fourierseries/-integrals. The documents work just fine when we enter the calculations at first, but when closed and reopened it does not work anymore. We have tried different settings in the “calculate” menu, but we haven’t been able to fix the problem. I have linked to a document, that won’t calculate anymore.Thank you in advantage.  

In MathCad 15, we were able to create styles for Headings, Titles, Subtitles, etc.  (dialog box at Format | Style...)  This was very handy to change the format of all the Headings at one time from one style to another.Is this same functionality possible in Prime 6?  As far as I can tell, I would have to individually find and select each Heading in the document and change its format.  This will become very tedious in large documents.

hi, i just started using mathcad. can anyone tell me the mistake i am doing here and how to stack the x[i and y[i into one column matrix. i am using mathcad 15.   Thank you

Hello Everyone. From : The question : Is it possible to edit the program, above to obtain the following output or a similar ? Thanks in advance. Regards.  

I have a quadratic with solve routine, but I cannot adjust the precision, as the results tab is greyed out.  Does anyone know how to adjust?        

The 6 is not good number: 666 Ward No. 6 by Anton Chekhov etc I am waiting for Prime 7. The 7 is a good number: 7 dimension in SI 7 days in week 7 notes in a scale 7 colors of the rainbow 7 ancient sages 7 Wonders of the World etc   What would you have in Prime 7 in first line?

… boys. Made in Mathcad!

Is there a way to find, and highlight, all locations and equations a variable is used in within a worksheet?  Similar to trace dependents in Excel   Mathcad 15.0   Thanks, Matt

Hi, I am trying to replicate an example I was given of plotting a bessel filter response. The example was completed with MathCad2.0 whilst I am using MathCad6 (if that matters). Everytime I try to plot the function I get an error saying "Plotting failed.Replace complex values and NaNs by real numbers". Can you please advise what I am doing wrong, I thought by taking the absolute value of the function I wouldn't have any imaginary component? I've attached the example and my worksheet for reference of the work.        

when printing Mathcad docs to PDF, they print as text error instead.  We are using output from Mathcad 15 ver 50 to print PDF's using Adobe DC Reader. They are being converted to text error msg. See attachment. Has anybody seen this

Hi!   May you help me to convert the 3 attached files from XMCD to MCDX?   Thanks a lot! Alessandro Bosisio

So Mathcad Prime 6 has a new symbolic engine.   There's no indication within the product what the symbolic engine is. However, if you poke around in the installation directory, there's a new folder called Axiom with an executable for the computer algebra system called FriCAS somwhere inside.   So I guess the new symbolic engine is based on this: https://en.wikipedia.org/wiki/FriCAS https://en.wikipedia.org/wiki/Axiom_(computer_algebra_system)   [edited to include reference to FRICAS]

  I am trying to use Given-Find to solve for 2 unknows.  Mathcad gives error saying this variable is undefined.  Please see Mathcad attached.  Wondered how to fix this.  Mathcad is attached.

Во вложении можно найти следующие справочные материалы для Mathcad Prime 6.0:   ▪ Прочтите это сначала,  ▪ Руководство по установке и администрированию,    ▪ Сочетания клавиш,  ▪ Что нового.

In the attachment you can find the following reference documents for Mathcad Prime 6.0:   ▪ Datasheet,  ▪ Installation and Administration Guide,  ▪ Keyboard Shortcuts,  ▪ Licensing Instructions,   ▪ Platform Support,  ▪ Read This First  ▪ What's New.

Hello everybody,does someone have news about MathCad Prime 6?Some timesheet?MCP5 has introduced too few improvements so I think PTC intends release new version soon. Or not?...ThanksBye

Good Day. I need your help with the following equation. I cannot get a solution for β. In the problem statement it mentions that α in degrees is 43.2 which in radians is 43.2/57.3 = 0.75. Then, the problem mentions that β = L/R (inductance divided by resistance), with R = 10 ohm, and Vm (maximum value of sine) is 120Vrms * √2 = 169.7Vpeak. When I substitute these values in, and try to solve for β I get an undefined solution (see attached worksheet). Please help me find what am I doing wrong. Thank you.

I randomly throw (1000 times! Keep a patience!) five points into a square and draw a second-order curve through them.These are seven curves:- a hyperbola (we can see one or two branches) and an ellipse (full or a part of it) - two usual cases;- a parabola, a circle, two intersecting lines, two parallel straight lines and one straight line - five rare cases! But the Seven is a fine number!Who will see all seven possible curves, must have good health, happiness and prosperity in the new 2018 year!   Physical Mathematics

why it does not work??   can you help me?
