Mathcad

Can someone help me please?   I'm trying to solve this sistem of tho couple differential equations using the comand Odesolve but I'm not getting sucess. (I guess that the error is in the red highleghted in the second equation).p.s. I'm using the Mathcad Prime 5.0  

I cant figure out how to get the maximum amplification of this bandpass. It keeps showing this error and i dont know why? Id be thankfull for any help since im quite new to this programm.

Hi all,I have new using Mathcad and then I have a chart in excel. How I can do that in Mathcad? thanks so much.

My university computers only have Mathcad prime 5 and I wrote my document in Mathcad prime 6. How can I create a file that I can open in Mathcad 6. when I try to open it there always comes an Error that this file is not compatible, because it is from a newer version.  

Hello, Newly introduced to MathCAD Prime 6.0 here and I want to put the following image as a matrix. Then, write a program where, at any given roof angle, between 0-30, and 1) if solidity ratio is 0 or 1, then interpolate to get  corresponding Cp value. 2) if solidity ratio is between 0 and 1, then do bi-linear interpolation to get a corresponding Cp value. 3) if solidity ratio is greater than 1, then extrapolate to get a corresponding Cp value. Would really appreciate some help on how I could go about this. Thank you!   *EDIT* I have now been able to convert this data as a matrix. I used another thread as an example to be able to extract the roof angle matrix, Solidity ratio = [0  1] and the Cp values matrix. After this I am stuck on how to program the conditions stated above. Please refer to the mdcx file attached. Also familiar with the linterp, and interp functions. But unsure on how to use them for my requirements.   

  The Laplace conversion of the step function cannot be converted by the new symbolic engine. P6.

Hello,   I am having trouble finding the maximum value of the functions x(t) y(t) and theta(t). I have attached my workbook I assumed this would be easy but I am unable to find a simple way to do this. Any help would be greatly appreciated.     

The formula of the corr function is given in Mathcad help. But correl is not given. I know corr is pearson coeffcient but what is correl ? What does it represent?

Hello I would like to convert a given set of data to a segment of straight lines, rather than a perfect curve. For example, in  the attached picture, I would like to convert the data for the sine curve into a set of straight line. Two examples are illustrated in the attachment. One is an approximation connecting the peaks and zeros and the other is more refined approximation. If I use the regression (least square method) on the sine curve, I get a horizontal line. Question: how to convert the given sine curve data into a set of lines and make them more refined, i.e., with the help of some refining variable. 

Hello everyone,   I have lots of datasets with different embankment profiles, see picture for example. Each embankment contains 1 or 2 slopes.    Is it possible to calculate the slope (in this case 2) within the profile. How do I select my boundaries for each slope on the x axis. I can connect my data trough excel as import or make x-y tables/matrixes in mathcad.   I use mathcad prime version 3.     Thanks in advance   Gerwin   ps seems I posted in wrong forum section. Can a moderater move my post to a more apropriate place?

Hello.  I have a problem with the units see .mcdx. The first one is calculated with units. The second one is calculted WITHOUT units. The second one is correct, is it impossible to make the same answer with the first one just with units?  Thx.

hello everyone I try to use help quick sheets and I wrote the following eq but I get the red line almost for all the results and I do exactly step by step im sure there is something missing here but I can not find it could you check it out and let me know what's is the problem  plz check the attachment  

Dear Mathcad community,   I have a problem when plotting a piecewise function. The error is "all evaluations resulted in either an error or a complex result". I would really appreciate if anyone can help me!   Thank-you very much.   Best Regards. Enrico

Can anyone explain why some equations do not work with the solver command and how can I work around this error?   Here's an example of one of these errors ... isolating speed is simple in this example but still gives error.   thanks in advance  

Can we use IF in the Given-Odesolve Block? See please the red operator in attach!

It's done

Hi, I have a problem with this task " Determine the center and radius of the circle described on the triangle. Draw a triangle on the graph and the designated one circle.   Someone can help me?

Hello PTC Community, I have been trying to plot a piecewise function in Mathcad Prime 5.0 but cannot seem to get the desired result. the mathcad's screenshot is attached. Please see what mistake am I making. Below the mathcad is the desired profile.my mathcadDesired profile (similar to this)

hello everybody im new here and try to learn Mathcad im struggling with an equation, somedays I keep working and asking and already I lean a lot I wrote an equation which  attached  here and  put an screenshot ,  there are value of I with different interval but what I  need now to solve and compare this equation with different value of R also  it means R has 3 different value 0.35 , 1.5, 3.5,4.7 as you see in picture each I shown with specific interval but R is fixed value

This is subjective  - but how fantastic is it.  What will this achieve that was missing from previous Prime.

I have a function that produce a series of Pi using Monte Carlo.   Is there a way I can use it in a loop so that it recalculates all its values of Pi each iteration?   Thanks

Dear members of the mathcad community,   I want to define a function within a function by considering the units of measurement. The function looks like g(f(x))= f(x)*a where "a" is a parameter. I know that there are other posts on the topic but unfortunately I could not solve the problem. Attached you find an example of my calculation. I would really appreciate your advice. Thank-you very much.   Best regards.   Enrico  

I have configuration files in INI format. I would like to read these in Mahcad. Can someone give me a tip as I can read the values ​​individually one by one in MathCad variables? Something like a := READ(File,Section,valuename)

Greetings,   I am working on this task where I need to plot a variable against time. However, I am getting an error saying "Plotting failed. replace complex values and NaNs by real numbers". Can someone help me sort this out?

Hi,   i installed PTC Mathcad Express to quickly check a file. I couldnt open it so i wanted to delete Mathcad. I am not able to deinstall it until now. I get this issue at the attached picture. However i can deinstall the programs "ptc mathcad prime 6.0.0.0" and "ptc diagnostic tools. I even reinstalled everything, still i get the same error.
