I have a velocity of a pendulum - see please the attach Mathcad 15 How can I calculate the position x(t)-y(t) by help of integral? Thanks!   PS What is a deferens between English speed and velocity?  

Hello Everybody, I have problem with my file, error in title has showed suddenly. I lost my all work which I have done. I don't know how can I solve that error. I only saved file and later I was trying lunch that. Then this error apeared. Sorry for my English. Can you help me repair that ? Good Night EveryBody !

Hi everyone, Very new here. Started using Math cad around a month ago and it have been fun Now I am stuck at iterative equation solving. I want to do it using a solver block so that it is nice and tidy here is the equation   I have tried understanding but am not getting it. Any help will be greatly appreciated.   Thanks

I have used this line of coding multiple times. Sometimes it works and sometimes it doesn't. I cannot figure out what I am doing wrong to produce random results. Can I get some advice.    My entire program is close to 100 pages so I am just posting a screen shot of the pertinent data.

Need help with creating this in mathcad

Hi I am very new to MathCad and have hit a brick wall with changing a range variable to a vector. I'm currently using Prime 6.0 in trial form.   my understanding is you define a range then define your vector based on that range e.g N:20 i:1..N a[i:i    I start the range with 1 but I always get the 0 index appear in my vector. Am I doing something wrong here? picture of my actual workings above (apologies my screen is obnoxiously wide)   It works OK if i input the vector myself   So I'm pretty sure its the range to vector technique I'm using causing me issues.Apologies if this is super easy I just cant see it right now.   Thanks for your help in advance.   Any help would be appreciated. 

r = -1 epsilon y = 60ksi/29000ksi   File is attached below, in the final page.   Thank you very much!  

Hello,in the attached sheet i have two question. please scroll down until you see the first red arrow for the first question, and scroll more until you see the second arrow for the second question.Q1. is it possible to combine different matrixes and display the values in a table with the heading of each column being the variable?Q2. Iteration until convergence. i have done 10 individual iterations to get the result to converge. Is it possible to do some loop to automate the iterations in one step. please look in my sheet that describe my iteration process.

how to find ω using mathcad?? 1. 2.

I recall seeing a number of posts, someone developing the equations for the spread and decay of a disease.  Here we have a direct, practical use for this math.   Anybody?

Hi, I have been trying to multiply each cell of the array by exponentially range variables. To illustrate: first cell of the matrix should be multiply by 2, second row of the array should be multiply by 2^2, third row of the array should be multiply by 2^3 and so on... Below illustrated EL(GR) should have seen: First row;1.06, second row should have been 1.06^2, third row should have been 1,06^3 and so on. I would appreciated if you help me to sort this out... Regarding Mathcad sheet is also enclosed.   

I used the derivative function but now i need to find L  how to do it ?  

Dear allCould you sold for me as attachment file below? Thank u  

I am doing an assignment on electrical engineering and differential equations, but i get a problem with "This value must be a function". I really cant see where the problem is and howto solve this. Mabye some of you can help to spot the error?

Having issues programming an Euler's method for ODEs. Can't get past error in magnitude of numbers. 

Hi! When i press on <setup> to install the program it appears to me that "the windows update for Universal C Runtime is required in order for the installation to continue". Also i mention that i made the windows update, but it still doesn't work...

Dear all I have a bit about matrix and I try to understand the dynamic of building structure , could you all share me the sheet of calculate mode shape of building as shown in example-1 attachment? Do for me  big thank all

I have two Mathcad sheets that I am using to design a structural member.  The reason I have two sheets is for two different design cases that have different loading.  Although there are two different design cases, the member geometry input for both cases needs to be the same.  I was wondering if there was a way to selectively link only certain inputs/ variables from one sheet to another?  My initial thought was that if you could initiate a link then then end/break it partway through the sheet, that may work, but I am not sure.  Due to different loading inputs the output will change, thus if I cant end/break the link, I will get duplicate output variable errors.  Thank you!  

There was again the question about Temperature units  I will tell one story. Ten years ago, I was in the city Boulder (Colorado, USA) in NIST and gave a talk about my program WaterSteamPro. They gave me the NIST handbook on the properties of water and steam. I leafed through it and saw that in units of thermal conductivity a degree of Fahrenheit, not a degree of Rankine. I said that in the old world and in Russia we have were not a wrong degree of Celsius, but correct kelvins. They told me that it’s easier to change the US constitution than to force American engineers to use here the right degrees of Rankine, and not degrees of Fahrenheit! But the most surprising was that in this Reference book in units of entropy and heat capacity were degrees Rankine, not Fahrenheit.    

What is the rationale for the change in region position on the page when changing from Standard Grid to Fine Grid and vice versa?  I don't mind the change in granularity, but I don't want my regions to jump all over the place when I change the grid size.Stuart

I've started a Mathcad Category in Rosetta Code.  If anybody feels like contributing, please do so and post a link in this thread (how does one get a Rosetta_Code label added?).   http://rosettacode.org/wiki/Category:Mathcad   Stuart

I am trying to write a program that implements the Foster - Cauer conversion algorithm described in summarily in page 19 of System-Level Thermal Simulation - nxp.com and thoroughly in appendix 2 of Aliyu, Attahir Murtala PhD thesis (that also includes an implementation in MATLAB) , but I cannot find how to program the manipulations they describe using MathCAD, especially the "polynomial long division" to obtain "quotient + remainder".   Anyone willing to help?   Note that I am using MathCAD 15   Thanks        

Dear all how to make multiple element by element and result as matrix? (Function As(DB,n,i)Thank you    

Hello, What would be the best and easiest way to approximate an integral or ODE by a mathematical function? Please see the attached MathCad 15 file. Thanks, Anousheh

Hello!  Im new with this program... but working for a while with MathCad 15.  Tell me how can i wrote index / parameter, like "." in matcad 15, not index for matrix... just simbol. Thank you for your time!
