How do I make a 3 phase sine curve plot. I am not able to make them with an angle of 120°? I have attached both an image and a file.

Greetings.I need convert binary numbers and show the process, for example:The binary 1011 is the matrix vector [1 0 1 1], need a program that make 2^3, 0^2, 2^1 and 2^0 then show a matrix [8 0 2 1] and later the sum 11 (8+2+1).Need show the matrix and sum, working according to the number of digits.Also need convert (based on block of 3 and 4 digits of) binary number to octal and hexa numbers.

Hi all,could anyone please tell mehow to write sech^2(x) in mathcad.I got an error while writing sech^2(x) in mathcad

Hi All,Does anybody know how to type "mean" value symbol?Basically a horizontal line on top of the letter.Letetr + " = this, but that means an operation (conjugate).I just want to have the symbol as my variable for statistics.I'm using MC 15.Thank you

Hi, I started using Mathcad a few days ago, and I´m trying to learn how to made some calculations for a paper. Right now, I´m having a problem to make an approximation with three different equations.Before, I made this same calculation with excel, but I dont know how to make it now.In this case, I have to calculate a velocity, and for that, I need a value, calculated by another depending of the velocity. So, before, on excel, I started with an approximate number for the velocity, then Ifigured the constants, then with that, I obtained the velocity again, and so on until the value of the speed began to tend to a very similar number varying in a few thousandths of m/s. Now, I´m not sure to do that step with mathcad. So I´m asking here for some helpWhat I need to is the velocity "uf", and  with that velocity, the constant to calculate are Rep2 and Cd2, the others variables are defined.I think twith an itteration I could resolve this, but I don´t know how to do it yetI hope I was clea

Sorry to have a dumb request, but I cannot find a way to get a cd.I am a gold support customer, using Win10When i get to the download or order software page ther eis no way to order a delivery.Can anyone help?

I have a problem using a solve block with equations that change at a specific point in the solution.  I've attached an example file (Mathcad Prime 3.1) showing the problem and how I've solved it.  The scenario is two vessels connected in series.  The first vessel is initially full of water while the second vessel is empty.  At time = 0, a flow of a second fluid starts into vessel 1.  The overflow from vessel 1 goes into vessel 2.  When vessel 2 is filled, then the overflow from vessel 2 goes to a drain.  I want to calculate the volume fraction of the second fluid in each vessel with time.  The equation for the volume fraction in the second vessel changes once the vessel is filled (because it starts to drain.)  The way I came up with to handle this is using the step function, but it does some strange things.  I've included two solutions, the first showing the problem with the step function, the second showing my messy-looking way of hand

I see that Prime is better Mathcad 15 with the work with units in the Solve block.See pleaseWard #45 - Sizes of a cone

Dear!When I try to open the uploaded mathcad file I got this messeage: An attempt was made to access an unnamed file past its end. I don't know that could be the problem since I don't changed anything in the file from last time I worked on It and It didn't chrased or something. Please help me cause I had a 3 days 0-24 work in It and I don't have enough time to start It from 0!Thanks before: Attila

Hi I am a newbie with Mathcad,I got something weird going on, that is when I am using the plot function to plot my equation, I don't get the y values in the chart matching the values of the actual function.If I start with a blank new worksheet it works just fine and I can't figure out what is wrong with the existing worksheet.The function I am trying to plot is Vmagn vs Imagn. Vmagn has the equation shown and will plot in y axis, the Imagn is a range of values and it will be the X-axis.Attached are the worksheets :Plot_with_no_problem.xmcdPlot_with_problem.xmcd (about Page 8- 9)The Vmag in the Plot_with_problem.xmcd worksheet is a lot higher then what it should.As you can see Vmag should start at 108 but somehow it starts at 2550.Let me know if you find the cause of this problem.I am using Mathcad 15.0Thanks,Adi.

Hello folks,I have here a set of equations in which I try to solve for a variable. First I used a vector to define distance l0 through l5, but Mathcad complaint that it can't accept units therefore I changed from vector elements to single variables with literal subscripts for l0 to l5.However, now the error says it is undefined. Can anybody tell me the source of the problem?Raiko

I need help to plot the shear and moment diagram of the one of the videos I have tried to use examples but it is big no go for me. Just so you know I am not coming at this completely blind. I have tried these examples :Load Shear Moment Diagram with Mathcad.avi - YouTubeshear and force diagram in mathcad pt 1 .mov - YouTubeI think they are using some different Mathcad that I can't use in own version of Mathcad. If I could figure out how to set up the function to graph and then the plot. I think if I try simpler ones then maybe I can move on to more complex ones that I am currently working on. thank you in advance for any help.

I'm working on a set of calculations whereby the input values are located at the top of the document and the values which I need to compare are scattered down through the calculations. Is there anyway of having the values required at the top, next to the input values (on the right hand page if possible so I can make them non-printable)? This way I am not changing one input and scrolling through everything to find what I need.

Hello, everybody.I have met some problem when i want to install the Flex License Manager. So, here's the detail of the problem.The server I want to install the FlexLM to.The server is a virtual machine which hosted on a VMWare. The server couldn't connect to the Internet and already have another FlexLM instance which runs at least 5 other licenses. The server only have a network interface (which is the same as the PTC_HOSTID line in the license).The documentation I've read.What I've (which I think relevant to the problem) read was : a. Mathcad License Problem - ptc_d daemon is down ... (Couldn't do it. The server doesn't have any PTC product installed yet.)b. vendor daemon is not being read...File not found, __PTCD_PATH__ (Already modified the license like that)c. Mathcad Prime 2 Installation, License Management section. (Couldn't use the setup file as the server couldn't and shouldn't connected to the internet).The installer I have.Mathcad 14 (don't know if the FlexLM can be installed

Hi,I’m trying a simple derivation with mathcad 15. At least I thought it was easy.The function is I want Mathcad to calculate But the outcome is obviously missing a term…Check the attachment for the corresponding xmcd or png.Can somebody tell me what’s wrong?Michael

Hi everyone，I have a task to solve complex differential Equations: The problems are as the following picture:It seems that these equations can be solved by Mathcad. Because, I can get any point's value. However, I can't plot it.So, my problems are:1) Why I can't plot? what should I do?2) The left table, which shows the P10_j, seems very strange. Why  the value is always [1, 1].Please kindly find the attachment, which is my input file of this task.Hope to get your help! Thank you very much!Jason

I used the READEXCEL command to create a matrix that I can use Lookup Functions on.The Lookup Functions work perfectly except I can NOT compare the values as shown below:Help?

Mathcad Prime gives me 11.833 as answers but need to get and show the equivalent fraction 71/6.How can we convert from decimal to fraction?

I am very new to the image processing functions in Mathcad prime or Mathcad 15.0.  In the image processing functions, I don't know what "melem" does.  When I look in the help files, it says that "melem" is a vector or matrix.  I can get my functions to work with a basic matrix but I really don't understand its purpose or function.  Does anyone else know?Thanks ahead of time.

Hello;I have 5 equations 5 unknowns in the solve block which all of them are functions of a range variable. Solve block always gives error, what is wrong?Please see the attached mathcad file below. Thanks for help

Dear Valery!Perhaps it has long been known, and maybe something I do not understand, but I have encountered such a strange situation - Mathcad 15 is completely wrong working with dimensional quantities in a solving block.Example - in the attached file.Regards,The man from the image of this group.All OK in Prime

To al,How does one create a surface plot like the example attached in mcad?ThanksRegards

That's the question,     What are the best free sources to learn mathcad?Thank you all.
