Mathcad

I am getting error such as picture. I tried to solve my problem. But I don't know. Could you help me?

Guys, I have solved a simple equation in two different methods. Can you please tell what I am doing wrong in the 2nd method thast i am getting a different result?Thank you

Hi, I am using mathcad 15 and am having an issue when using a given/find statement to solve a system of equations. I've constructed my equations and set them into the statement but keep getting a error that says "this variable is undefined". I traced the error to k5 but I checked and it seems to be defined. Can anyone see what my problem is? Thanks for the help.

See attach please

I have a system that has a number of thermocouples that is reporting a thermal strain. The strain appears to be dependent on the thermocouple readings, but not all of the thermocouples will affect the readings as much as some others.Given a dataset, how can I rank the influence levels of the thermocouples?

Hi -I have a problem with some of my results made in Mathcad Prime 2.0. The result always is either round up or down and aren't showing the true value - can you help? Look at the attached file please.Sincerely yoursDanny

Hi,I'm sure this is real easy but I can't see the wood for the trees. Given a function which uses a range variable as it's parameter. How do I convert this to a Vector for use in the fft function?Please see attached.Thankyou,Mike.

I am trying to use the Solve Block, but it is apparently just spitting my guesses back out as the solution. It is not taking into acount the known values. I haven't used MathCAD since ~2007, so I'm frustrated by Prime 3.0. the known values are the Droad....R. The guesses were Smc, and muI've tried drastically changing the known quantities, only to see no change in the output. I also tried moving the known quantities outside the Solve Block. Am I using the wrong "="sign ?I back-checking someone else's work(and relearning some MathCAD) and I know what values they obtained using a similar method.

I have a MCAD file from a version 12 that now requires a different set of tricks in ver 15 to make it work. I'm trying to understand why, and if there is really a better way to approach to original solution. We are not using MCAD Prime at this time.thanks,Brian

Hello,Another problem I'm having is with graphing if statements. I tried the milti-line one a I wouldn't graph and I couldn't get the single line if(test,true,false) to work. I have tried both with and with out units. The if statement doesn't like the variable with a range. I tried to do vectro selection, the [ , but that didn't work either. I'm sorry if this is a stupid question with an easy solution, I think it is. Thanks,

I am trying to check if my Minerr solution to a nonlinear-regression, Levenberg-Marquardt curvefit of a circle to data points worked correctly. I did not get an error message, so I think the iterations converged. But I cannot check simply by the error at each data point, because, obviously, it is a minimization problem, so one expects to get error at each data point - it is a best curvefit problem. I set the TOL and CTOL convergence-error values to 1e-010, and I still got no error message. So I think it converged, but I want to make sure. If I could confirm that a non-trivial number of iterations was performed, then I could be somewhat reassured. But if it stopped after, say, 2 iterations, then I would guess that something got misinterpreted by Mathcad, perhaps in the required vectorization.

Hello, Dear Mathcad users!It's my first lessons on mathcad prime 2.0, and I'am trying to create a plot with error bars (Y and X axis).I managed with Y-axis, but I cannot make the same on X-axis.Could somebody help me how to do it?The file I've created attached.Andrey KIselevStudent of Moscow State University.

Hi,I am working on this worksheet, and I cannot get Mathcad to plot my equation. I get the following error: "Plotting Failed. Replace complex values and NaNs by real numbers."I am not using any complex values and I shouldn't have any NaNs unless their is a syntax issue.I have looked through many resources, and I haven't found a solution to this seemingly simple problem.Thanks in advance,Charlie

Could anyone help me with writing a program to generalize the attached calculation?

Hello all,I'm trying to us the find fuction to solve an exponetal equation. I think my problem with the first Find(A.c) is that the value its solving for is around 10^-17 and it wants to say it's zero but can't becaure the value isn't zero. The second Find(T.f) I think is simular, I still get an error if I set a value for A.co. Ihave aslo tried to do this problem with out units and I get the same error. If anyone has any sugestions that would be great.

Does anyone have a fucntion or neat way to shapean area under a graph?

I wanna estimate k0, n, and k in the ODEs, but cannot let Minerr() run in my calculating sheet. but flexPDE can give a reasonable answersee the attached picture:

Where di I find the file to convert old MathCAD files?

Is there a function for natural trig outputand not radians ie sine(45)=.70711?

Hi all, Thanks is advance.I am making a graph for moments vs load radius..My Load radius start at 10.3m and hence the graph lines also start at that point (the vertical line in the document). But I want those lines to start from zero ( I mean y axis). How can I do so?I am making these plots against LoadRadius, Rw which has three values in a matirx but my other variables just has one constant value. So how can I put these constant value against three load radius, which will utimately produce a straight horizontal line. Here in the graph I have used a technique writing Friction= C*Rw/Rw which is not smart way I think.I am using mathcad prime 3.0Best RegardsJahangir Hossain

Does the information given by the system mean that mathcad cannot handle this kind of parabolic equation?

One of our engineers mentioned that text boxes always change size when re-opening a file. So if his file contained a text box with 3 lines of text when he re-opens the file the text box has changed to 6 lines of text and the text box is smaller. He said this has been on ongoing issue since time began. Can someone shed some light on this?

Document interaction in Prime is so awkward and time-consuming that it makes users mutter, "This is garbage," (or words to that effect) and swear never to to use Prime again. That can't be good for marketing or sales. These simple actions - moving around in a document, cutting/copying and pasting regions from one place to another, expanding and collapsing areas, editing equations and programs, and so on - are performed constantly when developing a worksheet. Making them easy to do should be a design priority. Yet, in that area, Prime is perhaps the worst of all significant Windows programs.It's serious. Although lack of some advanced features may disappoint users, document interaction problems actually repel them. Fixing those problems should be a priority, if only to keep PTC's user base.Some are listed below in the hope that they will be fixed. Anyone care to add to the list?* Prime is slow and unresponsive. The delayed imaging of characters when typing in a text box is merely irrita

I got error in left of the picture. so I did tracking. and I knew first error by using traking. But I can't understand the reason that error is generated. error is said that you can't divide '0'.

I tried to finish following process. But I continually got error when I coded.So I uploaded process steps. and I also attached my files.I am early step about studying 'mathcad'. So I want you to help.
