Mathcad

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.

Prime 6 new symbolic engine has a bug for RMS and Average values evaluation. Without using step function, how to do to get the symbolic results?  

  Here is the issue, I've tried every which way to get this summation to work, but it keeps giving me an "undefined variable" error.  I tried adding the matrix vector operator "[" to indicate the "i" index, but that didn't seem to work either.      Can someone point me in the right direction here?  

There is a problem about a skydiver https://community.ptc.com/t5/PTC-Mathcad/Odesolve-and-if-a-task-about-skydiver/m-p/205564#M80320  There is a problem about a gravity train (lift) https://community.ptc.com/t5/PTC-Mathcad/Mathcad-and-train-in-tunnel/m-p/480957  New problem! The paratrooper falls from the sky, the parachute does not open for him, but he does not die, because falls into the shaft of a gravity lift, but not with vacuum, but with air. What will happen to the sky diver? What is the pressure of air in the tunnel? Let t=20C! The density of Earth is constant!    

RL transient circuit symbolic bug. First answer only correct with old symbolic engine. bug Second answer only correct with new symbolic engine. bug

I created a simple calculation of the oscillation of a pendulum in Mathcad 15 - it does not work. The calculation worked when I converted it to Prime 5. I can’t find a mistake - there is no time - my wife is calling to go for a walk in the park - the weather is very good. I hope that when I return from the walk, someone will find a mistake 😉

I was verifying my math against simulation (PSICE) results and noticed an odd discrepancy when trying to plot the difference in phase angle between two transfer functions.   Comparing each transfer function's phase angle to its corresponding simulation result shows an almost exact alignment. However, comparing the difference between the phase angles shows correctly (or at least as expected) only for the simulation results.   What am I missing? Worksheet is attached (MathCAD 15.0 M050).

I can confirm the new SaveAs API function in Prime 6 works well. You can automate and save any existing file to a PDF. What wasn't mentioned is you can also use the function to save as a RTF file format. This can be opened directly in to Word as well. The quality of document in PDF and RTF is exactly the same as the Mathcad document. Very impressive.      

hi guys im new in Mathcad and learn so far but still some issue that I need to ask you I wrote this equation but im wondering how to add a range value to equation for ex in my eq I have R that it has 3 values R:=0,0.5..5 AND ALMOST ALL THE PARAMETERS IN EQ IS DEPOND ON R check the attached and help me please   

Hi, I'm a Quantitative Sciences student and a first-time user of Mathcad.   As I do not have information on the asset volatility, I need to compute the value of asset volatility using two equations. However, the comment said that "The variable is undefined.."   May I know how to solve it? Thank you so much.

Hello everyone   I installed MATHCAD15 and PRIME6.0.   But file converter has the following message.    The message is  " The conversion process could not be started."   Please advise me.  

Hello,   I am using the solve command to solve for EC for a given matrix of sigma.s, It is unable to find a solution. Please suggest.   Thanks,   Faisal

Hello,   I want to simplify my equation such that EC is one side only and free from others. I am trying to do it but could not do it. Please suggest.   Thanks,   Faisal

Hi All, I am a Mathcad user since the 1990s. With the new version, that is Prime 6, I find myself a little uncomfortable because the following things are missing: In comparison with Mathcad 15, they are:                1) animation for the graphics,                2) the definition of new types, (Format equation, user 1, user 2, ..., Format result.)                3) vertical and horizontal alignment,                4) selection of the entire worksheet with a click,                5) inserting subscripts or quotes in the text,                6)

In the attached mathcad prime 3.1 worksheet I'm attempting to utilize a solve block to determine the actual value of the variable xNA. A guess value was used earlier in the worksheet. Although the worksheet produces no errors it's setting the solved value to whatever the guess value is. How can I stop this behavior? Is it due to incorrect constraints?  

I would really appreciate advice on opening the attached MCD file. Itcontains vital data for our current research, and the collaborator whooriginally created the files is no longer available to help.I know that the file was created in 2005, but I don't know what versionof Mathcad was used. I tried opening the file in trial version ofMathcad Prime 1.0, but that didn't work. Then I tried opening it in atrial version of the older Mathcad 15, but that also didn't work; itsays "Failed to open document." Finally, I tried converting it with the"XMCD, MCD Converter" but this does not work; I get "Unexpected errorencountered during conversion."

Hello everyone,   I am experiencing the same rounding error from previous versions in Mathcad Prime 6.0. Have an explanation?  Or, where can I report effectively this error?   Thanks!
