Avec des valeurs données comment extrapoler une courbe dans le sens décroissant.

I've been working on a problem to determine the formulas for two sinusoidal fibers that are tangent to each other, as shown in the attached picture.  I've already pursued this problem with the GRG Solver built into Microsoft Excel and determined that there are multiple solutions, but I wanted to transition to Mathcad.  After entering the governing parameters and constraints I found that the solver functions if my guess is the same as one of my solutions, but if I change a guess (specifically for A1 or D1 in the file) it will not solve.I don't know if I'm doing something wrong with Mathcad or my constraint equations, or if I'm just experiencing limitations of the solver.I attached my Mathcad file with the most trivial solution entered, as determined by hand.  Slightly changing A1 from 1 to 1.1 causes the solver to fail.Can anyone provide any insight on this?  Thanks in advance.

I was using Mathcad prime 3.1 to symbolically solve a pretty simple equation and I get imaginary numbers.  While I was easily able to just do it by hand, I'm curious as to why it did what it did and how to stop it, if possible. The solutions I've found posted here and elsewhere don't seem to help (i.e. using various assume commands)File attached.Thanks,

Please!

Hey, im encountering an failure here:I want to use for every row another Dp as shown here:Thx ! 😃

Hello everyone,FIrst of all, I am very pleased to be on this forum.The reason I came here is to ask about solving equations with Mathcad.I have an assignment where I have to determine the three cicrular frequencies and periods of a free vibration (EQ. resistant engineering).the way I am trying to do this is using the lateral stiffness and mass matrices, [K] and [M]. In order to find the frequencies mentioned above I used the following equation:det [K - omega^2*M] = 0. My question is, how can I solve this equation using Mathcad? the mass and stiffness matrices are the size of 3x3. I am looking to find the three omega^2 values.this is what I have so far, but I am sure it is not right, because no omega should be negative.Thank you for your time and help,Sincerely,Aron

I have some experience in C language, and I know the structured programming, and in the structured programming there are no the "functions": break and continue as there are in MathCad programming.In Mathcad the programing paradigm is object oriented, declarative or another?

Hi,I am using Mathcad 15. My worksheet consists of calculations as well as graphs.When I try to save the worksheet in .HTML format (Save as Webpage) mathcad gives the following error:"Worksheet not saved"Please see the attched screenshot of the error.Can anyone suggest how to resolve this?Thanks,Ram

I already had mentioned it a while ago but was not able to reproduce it - now I am 😉has anybody already noticed the DebugPropertyWindow, where you can change some sort of things?Most helpful as I now can change the color and opacity of selected parts of an expression, which are normally very hard to spot on some notebooks and LCD screens.As far as I can tell, the changes are permanent and are global, not for the active worksheet only.I stumbled upon the keyboard shortcut while trying (to no avail) to get the OR operator via keyboard on my German keyboard - most shortcuts don't work as expected or do not work at all on foreign keyboards.The keyboard shortcut for OR should be Ctrl-Shift-@  (and now I know that on my keyboard I have to press Ctrl-Shift-2).For the @ character I have to press AltGr-q which did not work, but that way i found, thatShift-AltGr-qorShift-Ctrl-Alt-qbrings up the aforementioned  DebugPropertyWindow., at least it works that way on my keyboard.It works th

I have an unstable file in older Mathcad version. Can I request for help to convert it to new one ? When I open the file it crashes Mathcad (please see the screen shot below). I can email the file (I am not allowed to post it publicly).

Hi allIs`it possible to pull-out some coefficient or expression from matrix to show it in more compact (readable) form?Here I want to change representation of matrix only.Thanks in advance

I need help solving for "K" in this equation, symbolically. I'm not sure how to use the solve block for this, any help would/will be appreciated.

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
