Mathcad

I am very beginner user for MathCAD 15.I have a trouble that I cannot solve myself.What am I doing wrong in this code ?

Hi,Is there any way of plotting a function with the variable on the y-axis and the function on the x-axis, instead of the "normal" way?In the appended example, the "rotated" plot only plots the first ~10 m or so, then it seems to stop.Thanks in advance

Hello,I just started using MATHCAD prime 3.0 without any experience with previous versions of MATHCAD. My first task is to solve an ODE (nonlinear, first-order: as analyzed by mathematica):(dV(x)/dx)^2 - (dV(x)/dx|x=0)^2 = A*(exp(B*V(x))-1), with only two boundary conditions V(0) = 0 and V(d) = -VdFor the details, please see the file attached below.I guess the problem occurs because of the (dV(x)/dx|x=0)^2 term in the left-hand side of the ODE. But I do not have a clue how to fix this problem.I tried to be as clear as possible.Thank you very much,Sungyeop

Does anyone know how to add a title to a plot in prime 3.0? Add a legend or even label an axis? From my searching it seems these features are no longer available in Mathcad Prime. Also, I can't believe there are only three settings for the document margins! In the previous version of Mathcad I used (v14) I was able to customize the margins. Am I missing something here?

I have setup my worksheet to have the default display for Multiplication as 'X' as this is needed in the equations. I am using MathCAD 15 M020However, the X is showing between the numbers and the units. Between the units we would like a Thin Space.To get the Thin Space between the Numbers & the Units, I right click over the X between the Number and the units and select View Multiplication As.. and select the Thin Space. This then displays the correct format we required (Thin space between the number and the Units).This only applies to any number that is not in the same default value as the default units. The worksheet default is set to Pressure (Pa), and all of our units are in MPa. If you change a Pa unit to MPa, it automatically adds the X between the number and the units.After changing all the required X to Thin Space, I save the worksheet, close it and then re-open the it. All the X re-appears in ALL the places where I previously changed the X between the number and the Units t

to alli wnat to use the root() optin to solve a "simple" 2nd order equation. The 1st pass works fine but I now would like to set it up so that root() give me a set of x values for a set of given parameters. Please see attahce dmcad sheetthe equaqtion is as follwos a(A,B,t)x^2 + b(A,B,t)x + c = 0I can solve it if I set values for say A and tThanksRegardsJXB

hi, I want to solve the transcendebtal equation by bisection method or any other numerical method. but i am not able to get the answer. please see my attachment nd help me to solve.

Hello,I have 2 sets of data, X and Y, with the same length.How can I express one set as a function of the other one: Y(X)Thank you.

Hello Everyone,I am new to MathCAD so forgive me if this is a basic question:If you have an equation, let's say "a*b*c = d*e" where "a","b","c","d","e" are all variables and you want to symbolically solve "a", can MathCAD do this?Cheers,Jeff

I've got a worksheet that minimises a function with two variables.I'd like to get the minimised variables and re-input them into the function to find the final minimised value.When I try to extract the variables from the Minimize vector it gives me different values to those found initially - see attached worksheet.Worksheet overview:The function (Fresmin) adds FLres and FHres absolutely.Fresmin will be zero wherever a horizontal line crosses both curves in the graph.I define a value for RLD and use Minimize to find the optimum value of RHD.I extract the minimised values into a and b.I've also created a simplified example at the bottom of the worksheet that does work correctly.Can anybody explain why the former is not working? (It appears to be finding another solution as Fresmin is very small)

I realize this is a recurring issue, but have yet to find a reasonable solution. So, I thought I'd start this thread. Has anyone found a good way to run MathCAD on a Mac? Is it possible to hope that PTC might actually get it to work like other normal apps so it behaves in Parallels?

Hello,I'm brand new to MathCad, and seem to be stuck where the calc will not converge, so I'm not getting an answer... the eqn comes from my course notes. I'm trying to solve to give the volume of 3 seperate sections of an object, starting with the first eqn, yfl(x). This is supposed to be the "radius" when I sub in into Eqn 3 below to calculate the volume integral. Where Lf= 86.4, nf = 2.25 and D=36, as seen in the MathCad worksheet. Thank you

In Mathcad PM we do not need to transpose matrix with one row for working with it as a vector (as in Matlab or SMath):

See the animation Video Link : 5749

I've already set up the equation but i can't get this to work. What am I doing wrong?

helloAfter my PC upgraded to win7 professional. controls are disable in my sheet .why?

Hi,I just bought PTC Mathcad prime 3.0 (student version), and I have been trying to convert some files that I created with older versions of Mathcad (15.0, 11.0, etc) into the format of this new version. I read the document called: "Mathcad_Prime_Migration_Guide", and it says that I should install Matdcad 15 (M010) or a newest version of it to work with the converter of Mathcad prime 3.0. I downloaded and installed Mathcad 15.0 (M020) from my account at https://www.ptc.com/, but each time I tried to use the converter, the following log message was displayed by the converter: "Could not start Mathcad conversion process"Could anyone of you please send me a clue of what I should do to fix any error(s)?Thank you in advanced,EH

Is there a way to test if a variable is a matrix in Prime 2.0?I'm writting a function that uses the function vertflip. I want my function to accept a scaler or matrix, but vertflip only accepts matricies. So I'm looking to do something like...vertflip(if(ismatrix(M), M, [M]))

I have some questions. I have uploaded the Mathcad 14 file and here is a image of it.Show expanded function without replacing the variable per its values.Result in degrees. it wont let me select any unit. Only positive result. If I add: assume θ>0 the solve fails! Why?x-axis (θ) in degrees, not rad. The range is set from 0°-90° but it is still displayed as rad!

Hello, I have a spreadsheet which was developed by anohter firm and was made to use. I was able to make the dit to the spread shett the way i wanted it but when it came to the results at the end, I am not able to edit the already exisiting table (matrix) that is provided by the developer. Can someone please help me on how I can edit the "Analysis Results" on the last 2 page of the attached file. Thank you-NavP.S: I am trying to edit/delete few sections in the "Analysis Criteria" in last 2 pages.

Hi,I am having trouble looping through this program. I am basically taking the FORTRAN approach (attached) and trying to implement it into MathCAD 14. I am confused on how to make some of the change over.Any help would be greatly appreciated.

hi, guyshere is my problem.I want to connect pro/e with modefrontier by using trail file. So I first define some parameters in pro/e. However, in the trail file, there shows no parameter name just some numbers. Does anyone know how to modify trail file, in order to define parameters?here is a part of my trail file:~ Command `ProCmdMmParams` ~ Activate `relation_dlg` `ParamsPHLay.TBAddParam`~ Key `relation_dlg` `ParamsPHLay.ParTable` \5505140 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \4718696 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \524296 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \524296 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \4259937 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \5111918 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \4653159 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \3211313 ~ Disarm `relation_dlg` `ParamsPHLay.ParTable` \2 `new_added_row` `name`~ Activate `relation_dlg` `ParamsPHLay.TBAddParam`~ Key `relation_dlg` `ParamsPHLay.ParTable` \5898362 ~ Key `rel

Hello Community,My xmcd-file doesnt open anymore. Mathcad shows me only the message, that the file is destroyed. The error message give no further information what is wrong with the file. See the screen shot attached.I am using Mathcad 15.What do I need to do, to be able to use the file again?Thank you very much for your help in advance.Harald
