Mathcad

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

Does anyone else have the problem where the print quality of the chart components is abysmal?   When I print my Mathcad worksheets to .pdf the text and maths comes out great but the charts look a jpeg that has been saved 1000 times on Windows XP.

Hello,,, I  have the version 3.0 Prime (paid for this version while a study at the university). I got some interesting sheets that were apparently made in prime 5.0 version, so I can't open them in my version. I know is impossible to change it, because my version is older wich is ok, I just want to see the content as PDF and then I can rewrite it all. Could anyone tell me how to convert this sheets to PDF or if PTC can help me with this conversion?  my email is torres_52145@students.pupr.edu or ingtorremendez@gmail.com

Hey Guys,   I have a problem in Mathcad Prime 4.0 related to Integration problem and Plotting Problem NEED HELP ASAP Please ( File attached )

to allI am playing around with what is known as 'Frequency Response Assurance Criteria' (FRAC). I have attached an example  with some refI understand that the Freq. Response Function (FRF), noted H(w) is a complex function containing magnitude and phase informationIf one has got magnitude and phase info (at each frequency) (from a physical test) does one need to create a complex equivalent of the data to apply the criteria (A*exp(iw+phase)) ?In the case of the analytical data (FRF) I am not sure I can get the phase (but will need to check) as it is from a random analysisI found an example of a FRAC equation involving sum, see attached, assuming it is correct (not sure it is!), how does one "code" the sum? I did it but it look wrong. I interpreted the equation as calculating a FRAC value in a range w1 to w2. I f guess if one plots it one can see the "evolution" of the FRACThe example attached contains dummy vectors. I'll need to see if I can put my hand on "real" dataThanksRegards

I downloaded this application on to my computer ~1 year ago and used it fairly frequently.  I have just had a hard drive failure and have been trying to re-load everything, including this.  I go on to the website, fill out all the required information and submit.  It says I will get an e-mail with a link to allow me to download the application, but nothing comes.  I have tried the chat line and sending an e-mail to the address given - but nothing happens. Does anyone know what is going on?

I must be stupid.  I can't figure out how to add axis labels to an X-Y plot in Prime 5.  I found a new features post from a little while back that mentions the capability, but no hint of how to turn them on.  Nothing obvious in the software help either.  Can some kind soul steer me in the right direction?

One my little hobby is... clocks with one math sense! One example - a salesman problem clock!   

Hi folks,   I am trying to solve a second order differential equation in Mathcad 15 to model the diffusion of a substrate in a spherical pellet. Regrettably, Odesolve gives me the following message: 'This function cannot be used here' (see attached file). I have tried to rearrange the equation in different forms to see if that helped, but I still have the same problem. Do you know how can I solve the issue?    Best, Daniela

Hi, I'm a student and am unable to locate the Mathcad Prime license required to dual authorize the Mathcad 15 program. Per PTC instructions this file is "MathcadPrimeLicense.dat" in "C:\ProgramData\PTC\Mathcad Prime\license\directory" and similarly in forum discussions has been listed as "C:\ProgramData\PTC\Mathcad Prime\license\MathcadLicense.dat". Presently, althought I have successfully licensed Mathcad Prime, there is no "*license.dat" file that I can locate on my computer and the only files under the "C:\ProgramData\PTC..." directory are "Windchill sharepoint products" and 'PTC places NamespaceShellExtension". All other files reside directly under the "C:\ProgramData\Mathcad..." directory, but, nowhere can I find the license file.I purchased an HP Laptop with Windows 8 just yesterday (subsequently upgraded to the Win8 "pro" version) specifically to run Mathcad for a class. I have homework due soon, so, any help I can get in getting Mathcad 15 running would be most appreciated.Than

Hi, I am trying to solve a beam bending problem. My end goal is to solve a problem with more complexity, but for now I have simplified it so that I can make sure I understand how to use MathCAD. See the sketch below. I have a cantilever beam, supported on the left (at x0=0) it extends to x1. The Support reaction loads can be described as M0 and R0 which I am trying to solve for. The end of the beam is being deflected by Y1.   I have set up a solve block in MathCAD (Prime 2.0) as such:   But I get all sorts of errors. I've been reading about different solving methods including odesolve (I guess this could be seen as a really simple ODE, as well as symbolic calculation, but I haven't gotten any to work! Can anyone help me solve this? See the Sheet attached for the example. Cheers, Raz      

Hello, I want to find the function from 2 variables according to table data I have:    c t=16 t=25 t=50 t=75 0 4925 4511 4277 3845 20 4148 3975 3888 3564 40 3759 3672 3560 3327 60 3802 3586 3327 3111 80 3880 3664 3370 3025 100 4018 3698 3435 3089 120 4113 3802 3543 3240 140 4269 3932 3694 3435 160 4537 4104 3888 3629   I read a lot of info at this forum. I found good posts from @ValeryOchkov about the interpolation algo from 2 variables. I did it, but don't know how to get the function.    I attached a file with my experiments.  @ValeryOchkov maybe you can help me?   I am a newbie in Mathcad Prime, so please help me how to find the analytical function F(x,y) according to that data. Thank you in advance!

Hi there,   I have the equation below which Vout and Io are variables and I need to isolate Vout from the right side of the formula, but the function is too large to display.     I could manually isolate Vout, but I found a third order equation that again MathCad could not solve...    The problem is that I have two variables, Vout and Io and I have to plot a graph of Vout/Vin in function of Io.

Find the maximum value from a list of data and  also the value that results in the maximum data.   I have attached a mathcad prime 5 file and pic if you dont have Prime 5
