Mathcad

Does mathcad calculate all polynomials with numerical math or do they have an exact result. Thank you for answering.?

Hi,I am trying to get a solution in mathcad in which we provide a specific value (say 0) initially followed by set of equations and finally giving result.But if the result obtained is <> zero, program will automatically change the initial value until we get the final result (by trial and error) as or nearly zero.this is one example.Please help me solve this using Mathcad.Thanks.

I have a mass-spring system.  I am trying to back-solve four springs (provided in the attached file).There are four masses at which summation of forces are performed and A matrices are obtained.  The attached file shows them in the (Lamda*I - A) format. These springs and masses are configured in four different ways and their first mode natural frequencies are known. Therefore, in my mind, I should be able to use Given/Find in order to find the unknown springs with four equations while setting the determinants of the four matrices to zero. The solver doesn't converge.What is the problem here?  Can this be done?  If not, how else?Your help will be greatly appreciated.Thanks,Eric

Hello folks,this is about a basic issue hence no example sheet.For a lengthy calculation I'd like to read in parameters from excel. As this excel sheet is lenghty as well I want to check first whether the parameters in the Excel sheet match the parameters in my MatchCad sheet (naming and order of parameters). I'm thinking along the lines of making a one-to-one comparison of variable names (not the variable values!) in order to verify a match.Does anybody has an idea how to conduct such a comparison?Thanks in advance for any ideaRaiko

Hi, friends.Is there a way to solve the symbolic solution for a vibration system in mathcad?Such as f(t)=0, and the solution should be in the form of Asin(wt+a)+Bcos(wt+a)Thank you in advance!Looking forward to your help!Shawn

I am embedding some VB in a Scripted Object within a MathCad worksheet. I am trying to get the Worksheet object so I can get/manipulate some values in the sheet, but when I call ActiveWorksheet (or Worksheets for that matter) on the Application object, nothing is returned.I am inexperienced with VB so forgive anything weird I am doing, but feel free to point it out. Here is what I have basically. I get an error object worksheet is required on the last line of the Sub.Sub getValueEvent_Exec(Inputs,Outputs)  Dim objMC  Dim value  Dim worksheet     Set objMC = CreateObject("MathCad.Application")  Set worksheet =objMC.ActiveWorksheet  Set value = worksheet.getValue("value")End SubThanks,Evan

As suggested by the title, I'm attempting to fit a piecewise-defined curve to a set of data points.  This is also the first time I have used Mathcad, so it is exceedingly likely I'm missing something obvious.  My worksheet is attached to this post.I'm attempting to follow the example at http://www.phys.uconn.edu/~hamilton/phys258/P/genfit.pdf, but when I call the genfit routine, I get the error "This value must be a function".So, question number 1: what is this error message trying to tell me, and how can I resolve it?While I have your attention, I also have question number 2.  The function is a horrible mess because I'm trying to combine data points with continuity restrictions.  I don't know how to specify symbolic relations between fitting parameters (e.g. forcing the second derivative to be continuous at x = 60 yields "e = b + 24").  So I've solved the continuity restrictions by hand and substituted them back in.  Is there a way to get Mathcad to recog

I often see in a bus, tram, metro people with scooters. Here one has a problem - dirty wheels. But you can make sliding wings (fenders) of wheels, which will close at the wheel folding scooter. See. pls the animation.I created the animation in Mathcad and ask someone to do in Creo! Video Link : 6364

The focus of this study is to discover which factors affect the gas mileage of a vehicle by selecting and adjusting 4 quantitative factors.For the study we will use 3 different approaches.1.  A non-statistical approach for determining which factors and 2-way interactions should go into the prediction equation.2.  A statistical approach called ANOVA (ANalysis Of Variances) to assist making the decision in 1)3.  Using Regression for the prediction

Not sure if this is a glitch as such, however, when I have switched off show border for region, it still shows up in print preview and when printing.Has anyone else experienced this?Thanks

Hi!I can't find the reason why mathcad leaves the unit in the last row "y=5.5x10^7".

Here is the Mathcad 11 sheet that solves nth order differential equations with constant coefficients, referenced in the document thread with similar name here: A Classical Math Problem from a Classical Text (Differential Equation).Note that this, as it is, is NOT usable for:- Systems of differential equations,- Differential equations where the coefficients of the derivatives are not constants (when they depend on t).But in both cases, similar techniques can be used to solve specific systems.Luc

I am a new user of "PTC Creo Elements/Direct drafting (x64 edition) Release 19.0" Wen i am looking around on this website i see all kind of info over things that I don't need.For example "3D modeling, Mathcad, model manager, job server " etc etc.It's too much information for me. Is there any way so that I can see only info for the version i am using ?Greetz, Eddy

A sequence Ln is such that L1 = 0.2, L2 = 0.1 andLn = 2Ln-1 - 1.5Ln-2      ( n >= 3 )Use Mathcad to determine the value of L43, giving your answer to 2 decimal places.Need help to input this into Mathcad as i am new to this software... Still trying to figure it out...

Suppose f(x) is the following function, defined when x>0.f(x)=e^x - 3x - x^2Use Mathcad to find the x-coordinate, to 2 decimal places, of the critical point f(x).Question: How to input this function into Mathcad to get the x values? Any takers to help, I am new to Mathcad.

I have a time domain function (damped sine) in MATHCAD that needs to be fft, then attenuated by a frequency dependent vector. To do that I need to:- perform fft on function- interpolate the fft with the attenuationI have tried VECTORIZED with no success. Can anyone help with creating a vector/matrix from a function?

I'm rather frequently get stuck with Mathcad 14 claiming that a variable is not defined- but its not a variable but a function at the left side of a find statement,The solve block indeed works pretty well with a vector on the left side of the find statement.I have the impression that copying into a new sheet sometimes helps. I think this is an error by design.any help is highly apreciatedthanks

After upgrading to Mathcad 15 M040 I'm no longer able to open one of my files, "Unrecoverable error, two regions skipped". Same file still works perfectly with M030. Did someone had similar issues? Had to uninstall M040 and get back to M030
