Mathcad

Good morning friends of the group, sorry if my questions are easy, but I'm new to Mathcad. I don't know how to solve this type of equation, I would like the answer to be in degrees.The answer must be 120º.          

It would be great if Mathcad offers basic sketches which is always required in engineering calculations, with snapping options (grid, markups) along with tying the dimensions to the calculations. Sketches with the toggle option for transparent or opaque background would help in the documentation. Currently only option is using the PowerPoint saving as Png and inserting as picture in Mathcad (Which is involving and cumbersome).      

Hi How do I program an if-loop with a range variable, and not a scalar? Is that possible? 

Hello, What to add in below program for example in order to limit the values on x and y axis at: So that the graph does not have more than 10^307 points to display, even if the program has available to display more points greater than 10^307.Or what can be done in situations like this?                 I thought at below variant, but this variant does not differentiate in other type of  cases like division by zero:   If we run with the first program:

Hello,i don't want to read excel file to get the material properties for a given section. As you can see in the attached file, i copied the material section properties and pasted it into mathcad prime. Is there a way the user can select the material as i am showing below the table TC= " A22B", and have it look up certain section properties. I was able to do it in MathCAD 15. Thanks,Sam 

Dear colleagues, I have used the attached "Outlier Rejectionprocedure" for over 20 years to detect outlier data from acquiredthermo-structural tests. I have tried, unsuccessfully, offering the procedure to AEDC (Arnold Engineering Development Center) because I use one of the twoOutlier Detection Methods but they have not shown interest.Therefore, I am donating it to the PTC Community. The method is a simple average of the of AEDC's and Chauvenet'sOutlier detection methods criteria resulting in the formula: C_ABC(n) = (C(n)_AEDC + C(n)_Chauvenet(n)/2 Where "n = sample size" Ultimately, entered the numerical results into TableCurve 2Dresulting in the formula provided in the attached workbook. I have successfully used to determine the outlier of: Bolt torque (n < 16) in a pipe-to-pipe flange assembly.Metal temperature around turbojet engine inlets, n < 24.Metal temperature around turbojet engine nozzles, n < 18. It is my hope that

Hello everyone,Please look at the attached MathCad worksheet.I would like to know if the solution block for my problem can be simplified by using the Minerr solver.The solution block must solve for 192 equations.Thank you so much for the time and help.Regards,CarlosRomero     

Hello,   OK     Not OK?! Should not be    ? x being any number     Not OK?! Should not be  ? x and y being any number

Hi I have a query on the backward compatibility of Mathcad Prime 9.Can I directly open in Mathcad Prime 9 the files created using Mathcad Prime 8 or Prime 7 ? I understand that for file created using Mathcad Prime prior to 7 and Mathcad 15, we would need a convertor.  Warm RegardsVijay 

Hi  - I am exploring the possibility of having the calculation logic in Mathcad file, and then having the .NET web app take the user inputs and then sends the input values to a Mathcad file running on the server, and then get back the calculation outputs from Mathcad - which will be displayed on the web app.  - Does the Mathcad API support the above scenario? I tried to check this link - Getting Started with the PTC Mathcad API | PTC | Mathcad - But it is not opening for me in either Chrome or Edge.  - When Mathcad is called, will the Mathcad run in the background - or for ex; in case of a .NET desktop app which is using Mathcad installed on that desktop,  can the user see the Mathcad window - when it is being called from the .NET code ?  RegardsVijay  

Hello,   1. I would like to know how many sign changes there are in this vector viewed as a matrix. There are 8 sign changes as far as we can see: So, here I would like a function that shows me 8 as output (the number 8 being the number of sign changes).2. I would like a function that tells me that at column 0 and between lines 1 and 2 is a change of sign, that at column 0 and between lines 2 and 3 there is a change of sign, etc. :

Hello I am trying to use Mathcad Prime 7.0.0 to solve equations, but no matter the equation, i have tried many, it always gives me Mupad_Unresponsive. Below is a simple example of the problem i have been encountering. P.S. I have tried uninstalling license, both in appdata and user, reinstalling mathcad, still doesn't work.    

Where did I go wrong? Watt should be kg⋅m^2/s^3 Thus Watt/m^2 should be kg/s^3So the base unit reflected in the first line is already wrong (and the result off by x 100). I tried again by changing my custom unit in 2nd line and it confirms that the unit went awry somewhereThis is mathcad prime 8  

I found a puzzle in the book store. It is 20$. I make it by Prime 9 worksheet. It says it has two answers. Try it!  

I'm trying so solve an implicit differentiation example but I keep getting bad solve variable error This is my example:x^2+y^2=25   

Hello, How to extract for example the 13th element from below?  

I am upgrading an old application server and would like to know if there is a way to migrate the current version of Flexnet License manager 2016 along with my MathCad licenses on to a new Application server.   

Helloi am having issues with units when i use the solve function. I have never had this problem before but it seems like whenever i use the solve function, some of the standard SI units are deleted in the process (the unit isnt bold blue anymore, which is what indicates that it is a unit). This is very frustrating because i need to copy the whole solved equation down and solve it again with a standard = then it comes out in the right unit, but i have never had to do this before, and in most cases i also need to define the units again in the copied solution... i attached a png of one of the times this has happened - and now it is happening in all my new files    

Initially posted in this topic   Hi all, i can understand this for single dimension vx and vy, but what about 2 dimensions Mxy and Mz? Could anyone explain what cspline() returns and how interp() works? Thx in advance!LertNote: i use mathcad 15.

I am computing phasor values of voltage & current waveforms at each sample point along the waveforms.  I want to plot all of the resulting phasors, aligned to a-phase voltage.  To do this I simple need to multiply each phasor by unity at an angle that is the conjugate of the a-phase voltage angle at that point.   Is there a way to create a polar shift operator 1@-arg(Va)?    See attached Prime 8 file for how I'm doing it now (multiplying by the conjugate of Va and dividing by its magnitude). thanks,russ

Hello! I've been a MathCAD user for 5-6 years now, but this last subscription cycle I told myself would be the last. Instead, I wrote a prototype application that just barely meet my needs, but shows an example for what cloud CAE could be. I would love to see PTC adopt something like this into their offerings, implementing storage, global variables, syntax highlighting, autocomplete, and hooks into Onshape. The graphical nature of MathCAD is neat no doubt, but I think the future is plain text with a super simple syntax. It's free, so please check it out if you're interested!https://fa.rad.cm

Hello, I want to see a variable from an equation. But I did some practice, and I couldn't get any solution. Can you help me I attached the file. 🙂  

Hello, I have this vector:     I want automatically to eliminate duplicate elements, and to retain only those elements which are not duplicate from the vector: How to do this?

Hello, In Mathcad prime, when a value is looked up from an Excel sheet, the output will be placed in a square bracket , I assume it is an array. When I use the looked it up value and compare it with another value, it gives an error saying it must be a scalar. What do I need to do to the looked up value to make it a scalar? Thanks,Sam
