Mathcad

  Can you please help me solve this issue? I don't see any faults on equation. Please let me know if I am overlooking at something. Thank you. 

Hello, Please let me know if PTC still officially supports Mathcad Prime 7. Is there any official PTC link where it is stated that this version of the Mathcad Prime software is officially supported? Warm RegardsVijay

Hi,I am making something wrong? Are only 3 differential equations... But using laplace command this system of differential eq can be solved:   See MCP9 file attached.

Good morning,I would like to convert xmcd files to mcdx format.I have Mathcad 15 software and a trial version of Mathcad Prime.The conversion is refused, probably because Mathcad Prime is a trial version.Could anyone convert them for me? I have about 15 files.Thanks in advanceRichard

How I can  tell matcade when the angle is divided by zero consider the value to be zero   

I'm trying to calculate the distance when I do it manually I get different results from the one mathcad givesLp1 should be the same of LP1I also need to write a program to make this function uses different fixed point , for example the first time it will use X1,Y1 (0,0) as fixed point and I get the values for Lp1 the second time it uses x2,y2(2,0) as fixed point and I get the values for Lp2 and repeat the process with the all points to get lp3, lp4 ... and so on

Hi,For below circuit:1. Find the expression of the voltage across C2 (Vb) at t>02. Find the voltage across C2 at t=100ns when C1=100nF3. Find the voltage across C2 at t=100ns when C1=10nFAlso let C1 and C2 voltage  as t-> infinity to be Vb.    

Hello Experts, Please help me with the Subject issue, "How to extract the several Sol Data to one Excel sheet through "WRITEEXCEL" function?" In order to reduce repeated works as I should handle many cases, I want to extract several Sol Data into one Excel Sheet file but no idea :(( Please check the attached mcdx file for the following questions.1. How to get all of the data values(Sol, Fy, y, y1, Fx) highlighted with yellow color in one sheet of Excel file by using "WRITEEXCEL" fucntion? 2. The value of Fx is same for all the variables of each matrix row which shouldn't be correct. Is there any mistake for that? Please give me any advice or solution. will be much appreciated. 

Why can't I get a 30-day trial? The previous owner used up his test period. I am a new owner of a laptop and by entering new data I cannot obtain a new trial period on this laptop. What to do?   Translated by the Community Moderation using Google Translate ----------------------------------------------------------------------------------------------- Dlaczego nie mogę uzyskać 30dniowego okresu próbnego?

Good afternoon,I'm sure someone on here can assist, we are fairly new to using Mathcad and we are struggling to get the lambda formula in the below snip into a Mathcad sheet, it throws up a number of errors and we aren't sure what numbers we should be adding where.  If anyone can assist, we would be very grateful.CheersSimon  

I have an already filled in Excel sheet with parameters and variables that I use in a Mathcad calculation. I could copy 'n paste the content to an embedded Excel component, but I'd like to avoid such menial task. Has anybody figured out whether and how to insert an Excel component that has content?

Hello guys,I need some help.I am trying to solve the following problema.But it seems I'm stuck on the binary variable and this causes errors in the constraints.Can anyone help me out of this jam?CarlosRomero

In Mathcad 4.0 it is not possible to show date in ISO 8601 format (YYYY-MM-DD), e.g. in the page header.As this is the format we are using in our office, I'd like to add that as a choice.

Hey, I have problem with system of differential non linear equation. I dont have any idea how to solve this. I hope you will help me 🙂 

Mathcad Prime 9.0.0.0I'm doing a separation of variables equation, where I start with the equation at the top left in the screenshot. Using the solution that mathcad provides from the integrals, i get an output, that doesn't match up with the true answer (highlighted in blue). Am I using it wrong?

Hello,I want to extract for each iteration o i, the corresponding value in 20log() vector at index i, and put that value into another vector.     And so on..

I  want the values of qcsand to be only between 5 and 25 I how to fix that 

Hello,These examples are for each particular i:   But how to iterate through all values of i:

Both of the variables have the same unit, however mathcad said units are not compatible why is that?

I truely don't know why this error keeps happening?!

Ideally when we use the vectors with function it should give solution for individual input. I think I am missing something?  

Hi, I'm new to Mathcad Prime, having used 15 for a while now. I've been looking with interest at the API offered with Mathcad Prime, and I have had some luck in recreating some of the various PTC examples in MATLAB using  actxserver("MathcadPrime.Application")  to link the Mathcad COM server to MATLAB.Where I'm encountering issues is extracting values from a matrix. Using the test.mcdx file provided with the VBScript example, I can retrieve the value of output1 successfully, however I'm struggling to do the same with matrixOutput1.I'm using the following to load the matrix: prime = actxserver("MathcadPrime.Application"); %%Open a COM session for Mathcad prime.Activate; %Focus the Mathcad window (not necessary unless you want to see what happens) dir = "C:\[...]\test.mcdx"; %Path of worksheet to open ws = prime.Open(dir); %Open the worksheet and create an object to represent matrix = ws.OutputGetMatrixValue("out_0") When I query the rows

So, Prime 10 is imminent eh? The trumpeting has started and the new enhancements that are touted sound like a list of corrected bugs. Undoubtedly, there are some useful improvements but I fear that the big one is still missing. This big and very visible problem with all Prime versions to date is the very poor quality of the plots. Compared to the MC15 (of blessed memory) plots they are very primitive and limited and definitely not presentation quality. And for technical applications good plotting facilities are an absolute necessity. So, as it stands now, if you need some proper plots for, say, a presentation, then you have to export the data to Excel and try to make a plot there. For technical plots that's often not optimal and you may have to resort to a freeware or paid plotting package like Veusz or so for, say, decent polar plots. Well, that's irritating and cumbersome to say the least. To improve plotting  facilities start with a look at the MC15 plots. They had their l

In this case I want  to allocate a result of substitution to Eq1, It seems to works for the substitution but  then Eq1 seems undefined. What happens? Then it might be the reason why the 2nd substitution is endless.  However, when i try to make 2 substitution in the same execution command, it is endless too.What happens  ?  Is there a relation between those 2 cases ? Option calculation for constant unit with symobilc math is set.PTC MathCAD prime 9.0.0.0.0
