Prime 5.0 Electric Circuit  When L=1 my Mathcad sheet shows no error. When L=2 the sheet has an error.   I want to know the reason of my error.      

I'm not sure what's going on here.  I'm reading in a file and trying to get Mathcad 4.0 to add units to a column.  But it's not working as planned.  Tried a few different variations but always get the same issue.  What am I doing wrong?  

Hi Friends,   I am trying to write a formula for evaluating some conditional statement. I have an old pdf of that Mathcad sheet where all these calculation had been done but unfortunately I do not have this file with me. Can anyone tell me how can I combine return statement with if statement as shown in attached image.    This is also done in Mathcad but do not know the version. I am now using Mathcad prime 3.1 to do the same thing. I can use IF statement with else function here to get the desired output but first preference to write the formula in a similar way as shown in figure attached.   Thanks

Is there anyone converting my file mcdx to Xmcd or mcd?

Hello everyone. how to open a Worksheet file of mathcad prime 5 in Mathcad 15 ?

I am in school and trying to work through this example in the book. It all works out except the Theoretical Flow Rate which the book specifies as 15.3 GPM. From a little research I believe the issue is with how MathCad defines rpm but I can not figure it out.  Any help would be greatly appreciated, Frank 

Is there any way to generate the voltage and current equations from spice netlist using Mathcad prime 5.0??

Hello,   I have been trying to solve this equation however no matter what I tried, I couldn't come up with an answer. All the functions appearing in the differential equation is defined but at the end, it can not solve. What is the problem? I also included the file I am trying to solve.

Hello,   can anybody help me to find out why this FIND doesn't work?   Raiko

Hello since im trying to find the unknown with 6 different initial values and 6 non-linear equations I try to use find but I cant obtain the value but there is one variables in the equation got counter.Hope u guys can check for me.

I wanted to create the Y BUS matrix from Netlist and solve that to get currents and voltages of each node.   For this i need to know how to solve the AX=B in matrix format, if all matrices(A,X and B) having variables only, I want X in terms of Varibales(eqn)   Please check the 29th page of this pdf: http://www3.imperial.ac.uk/pls/portallive/docs/1/7292571.PDF

How to insert values previously obtained into a table (as shown in the last of the attached file) without manually typing them. and trace the graph pV.    

Is there an option in Mathcad where I can solve more equations that depend on each other?There will always only be one value that is unknown. Hope you can help me 🙂  

why the same inverse is not working in program?, but outside its working fine,  Please check the attachment.

Hi all,I want to get some knowledge about MathCAD Prime and for better understanding I made some simple calculations.I have done a simple example to get familiar with MathCAD solving functions.I want to calculate the charging time of a capacitor for two different voltage thresholds. have attached a pdf file of my MathCAD sheet.What I have done in MathCAD delivers the right results but the intermediate steps are wrong.Can someone explain me what I have done wrong?Thank you for your help!

I have a set of data that I am importing from excel.     I am reading data from the file. It is in the format. "[79.34029,63.57957]" (There is a column of data)   I want to convert this to 79.34029,63 at an angle of 63.57957 degrees.   I tried reading it and used str2num but it did not "like" my approach.   Thanks for your help.  

Hey Guys,   So, i'm trying to do For loop in my file to define a concentration changes in respect to x. The approach used :  I have to first solve the CO2lSS with ode solver and resulted in CO2lSS(x). And from there i substitute into the equation of CO2gSS(x) equation, where inside the equation there the CO2gin and CO2lin which i want to do iteration.   CO2lin (n) has to equal to the CO2lout (n-1) and CO2gin (n) has to equal to CO2gout (n-1). Where n is the number of cycle, and each cycle is 250 m. So i want to make a loop where everytime the concentration reach x=250 m, that value will be used for another concentration in value.   I tried but it still gives error. Hope you guys can help. I would really appreciate it.   Thank you. 

I am writing a paper using as math editor Mathcad, but when I write an equation that is missing a value or a previous definition, I have a comment, for example: A name is required here" and the mistake in the equation will be in red.  Being in red affect the possibility to copy and paste the equation in a word document. is there a way that I can avoid the red color when a mistake is happening in an equation? I want that the equation look with all the letters and symbols in black.   Regards,   Rogelio

What is it - an error or?

how to solve this equation to define n1 by using successive approximations in mathcad [1.34 .. 1.42] a=20.44 b=0.003572 ε=17 Ta=333.95 n1 - 1 = 8.314/(a+ b*Ta (1+ ε^(n1-1)))

Hi, how to matching this two equation for define a and bc(t):=2.47+0.0036tc(t):=a+bt

 I am trying to solve a second order ordinary differential equation. I had attached mcdx file for reference.  It says " This Value must be a function". Please suggest the solution if possible. my final requirement to plot the x(t), x'(t) & x''(t)

I just purchase the lisence and wanted to activate it but there is always an error occurring and i can't find anything on the internet because it's a german error message.   I've attached an image, perhaps someone can help me.

Hey guys I want to ask,   When I have two derivation dCOl/dx and dCOg/dx, there are two ways to use ODE solver : First by solving it in 1 term (so its coupled) or second by solving one of each first.   I tried it and it gives a different result, now i'm wondering what is actually the difference when I do derivation coupled and uncoupled.   Thanks
