Mathcad

Hi!I'am having a problem wanting to solve a third degree polynomial. This is ok, and mathcad retuns three solutions, but I want mathcad to return only the solutions within a defined range, e.g [0,10]. I have tried to this with an if-function, but no luck there. Uploading a file. Someone please help.BA

Hello Folks,I would like to have a fancy listbox where all the logic is external and the listbox is used merely for choice and display -  such as in the pic. Does anybody have an idea?Raiko

Correct names Mathcad and Mathcad Prime are Mathcad and Mathcad Jr.There are a Father and a Son.The Father is much more experienced than his Son, but the Father had a career coming to an end.The Son can not yet do much of what his father could do.But the son gradually from perenemaet experience of his father and learns a lot what you do not know the father.Yet there is the illegitimate son - SMath.

How  do you solve a boundary value problem in mathcad prime 3.0 with a solve block?  I have been wondering about this for a long time because I want to use it to solve Schrodinger's Equation. Can it even solve BV problems if there is not a unique solution?

What happened to "solve for variable" in Mathcad "Prime" 3.0?  That was one of the most useful features in all of Mathcad, and it really isn't worth having without that.

Hi everyone,I'm a student and I'm new in PTC. I'm trying Mathcad Prima 3.1 free for 30 days. I have a little problem. Sorry if this is not the right section to post this question.I was trying some elementar functions and when I want to raise to power using ^ button, Mathcad returns me the command "if ||" for programming. What's the matter? Using a text box there are no problems. I've tryied all the shortcuts and everything works. This is the only problem, my shortcut (^) for raising to power doesn't work. I'm missing something? Thank you very much for your answers. Best regardsDavid

Hello fellow MathCad users,Is it possible to display the numerical value of variables in a line of calculations. For example if I was to calculate the strength of a beam. I want the calculations to look like the following:Depth of beam:                D = 300mmBredth of beam:               B = 125mmSection modulus:             Z = 1/6 * B * D^2 = 1/6 * 125mm * 300mm^2 = 1.875 x 10 ^6 mm3Bending strength:             fb = 38 MPaStrength reduction:          phi=  0.8Loading duration factor:    k = 0.8  Bending strength:            Mn = phi*k*fb*Z = 0.8*0.8*38MPa*1.875 x 10 ^6 mm3 = 57 kNmFYI I have MathCa

How do I backup my MathCad product in case of failure or hacking of my computer?Regards, K

I was looking at some of the Rosetta Code challenges for implementation in Mathcad and decided to try a couple in Prime Express (as this is what I have).  The major drawback to Express is the lack of programming capability, but there's quite a bit that can be (or should be able to be done) using just range variables and functions that don't make use of programs.I wanted to pick all of the non-zero elements out of a vector and decided to use the until function to sweep through a reverse sorted vector until it hit a zero.   However, Prime keeps telling me that 'until' is undefined, even though I inserted it using the Functions Dialog. Express doesn't raise an alert saying that it's Premium Feature, so I'd expect it work. Neither can I find anything in the Migration Guide or Help to indicate it's been deprecated.  Is there a known problem with the until function in Prime 3.1?Stuart

I am trying to replicate something done in Mathcad 15.0 in Prime but I am having difficulties.I would like to double integrate two functions, but can't get a function dependent on two variable to work.I have attached my best try, and a pdf of how it was done in Mathcad 15.0. I can't get the n(x) to work in the gamma,h1(x) function. I am able to skirt this for a while but never get my integration to work. Please see attached and thank you in advance for your help. AlanStevens‌ I feel like you would have the answer looking at one of your other posts.

Hi,my problem sounds rather simple but still I do not a have a solution in Mathcad. In order to automate my Mathcad 14 sheets I would like to check if a variable is defined or not.If the variable is defined (not red colored in Mathcad) this on should be used instead of an different. Thanks Holger

Hi everyonecan anyone help me to find the best distribution: weibull or exponential distribution for this data using Mathcad, please?1.393    0.66    1.032    0.336    1.451    0.489    1.123    1.789    1.542    0.051    1.654    2.813    0.736    0.637    1.477    0.859    2.017    0.391    0.754    0.26    0.127    0.725    0.842   0.28    0.396    0.022    0.623    1.205    0.312    0.986    0.534    2.818    1.184    0.656    0.315    0.806    0.444 &

Hello all,I'm working with the WRITEEXCEL function for the first time and seem unable to make even the most basic example work.  In the attached file, no file gets written and I am unclear why this would be.Best regards...

I have this conditional formulas between satisfactory and fail .  How can I turn text into a red color if the condition is "fail". Only the FAIL  text will turn to red color.

Hi to everyone here!!I have a worksheet for rail calculations and I am used collapsible areas to hide certain information on the printout, however when printed the collapsed areas still show.  Is there anyway to get these areas to not print in MathCAD Express Prime 3.1?  I have attached the sheet I am working with for any ones reference.  Thank you in advance for your input.Sincerely,Justin Kordas

Hello every one>i need  a graph like that using Mathcad, Can you help me please?

As a result of Valery's clock problem, I have unwittlingly found myself exploring elementary number theory.  This has entailed a rewrite of several of my standard library functions to work more effectively with different bases. It has also meant modifying the behaviour of some of Mathcad's built-in numeric functions, such as Mod, Round, Trunc, Ceil and Floor, to handle complex numbers.Currently, Mathcad (not sure about Prime) allows one to enter numbers in decimal (default), binary, octal and hexadecimal, and to display them in this format through the Format Results dialog.    This is a bit of a pain if one is working in mixed bases (which is usually the case) and it would be a lot easier if one could simply enter the (arbitrary) base as part of the number entry or display. One possibility is to write pseudo-unit functions, as in the example below:However, an alternative, and one that is in keeping with the majority of texts that I've looked at, is to put the base (

Several classes of problem (eg, context-free grammar interpreters) are easily thought about and implemented by mutually recursive function calls,For example, one of the Rosetta Code programming challenges is to implement the Hofstadter Female and Male Sequences (http://rosettacode.org/wiki/Mutual_recursion#PureBasic).  As far as I'm aware, this isn't possible in Mathcad, but appears to be in a whole host of other languages including Matlab and Mathematica (two of Mathcad's major competitors).   As the ultimate humilation, I wrote my first program in LibreOffice Basic to show that even a word processor can do mutual recursion whereas a mathematical application can't.  Indeed, it seems as if even a pocket calculator can do it (see Ti-89 entry in the Rosetta listing).StuartRosetta Code Hofstadter Female and Male Sequence ChallengeTwo functions are said to be mutually recursive if the first calls the second, and in turn the second calls the first.Write two mutually recu

Hello,I have a done calculation in mathcad to check my design for safety.Now, i want those inputs used for calculation in mathcad to become parameters in creo. These parameters i want to use in notebook which will drive my assembly.Also , if i change my design in mathcad, corresponding change should occur in notebook parameter and so in assembly.If direct link is not possible, excel as a link will also do.thank you for you time.

The requirement of a hand held graphing calculator for AP tests in physics, chemistry and mathematics is prolonging the transition to Mathcad. AP Calculus AB Calculator Policy MOOCs are having enough of a problem deciding whether MATLAB, R, Python or Excel is the proper replacement for the hand-held graphing calculator.  Mathcad is recommended by only a few MOOCs.  This is a marketing problem PTC should address.  I have been using Mathcad instead of the calculator included in the MOOC platform because of the superior way it handles units.I started out with a K&E slide rule, progressed to an HP RPN calculator, did everything possible with a graphing calculator, but now I'm using Mathcad.

Hi there. i am trying to graph a projectiles trajectori with air ressistance. I have been trying to program a while loop, which for a small increment in time will figure out the X and Y coordinates of the projectile. I think i have done that part correctly, but keep in mind i am a rookie in mathcad. My biggest problem is thus after the loop has come to an end, how do I store the data points and graph them?i have attached my mathcad document, any hints,points or solutions would be much appreciated.

Attached is a short worksheet created in both Mathcad 15 and Prime 3.1. The graph at the end of the worksheet works in 15 but not Prime 3.1. I've attempted to make them the same but there is an error in the 3.1 program. Might folks know what is the error in the Prime 3.1 program?

When you resolve a system with variables that have associated the units of measure and where the vector of the results contains different kind of units, you may have problem, not to resolve the problem, but into the view and extrapolation of the results.I have resolve this issue in this manner.Bye!
