Hello, i have problem with Mathcad 15 how to calculate 4(x-5)(x-6). I want receive polynomian 4 x^2 + 44x + 120.I also have a second problem, when i calculate matrix i receive simple table like in Excel program, how to change view this matrix to ordinar view.

I developed this analysis for a court case I was working on.  I operated on about 100 years of precipitation data. The mean and median of the data set are quite close together.   I developed probability plots as well as histograms of the data.  I then did an autocorrelation analysis.  Turns out the annual precipitation data appears to follow a normal distribution and the data is not autocorrelated.  It therefore appears that statistical tests for the normal distribution can be used to make predictions about future precipitation amounts. 

hello everyonei have this problem guys. ive been trying to solve an equation system for a thermodynamic problem using the given/find commands and when i try FIND i received this error " this variable is undifined". i really dotn know whats wrong with my equation system. if anayone could help me out and explain whats the problem in my MCsheet. i would apreciate it.the file is attached.

Hello! How can I find symbolically the ex,ey and Phi variables? I have tried with solve block, but the solution was the guess value.See the 3 equations in the attachmentThanks in advance!

The question of how to save the state of controls in a Mathcad worksheet comes up so often I decided to post the answer somewhere I can easily find it and post a link to it!There are two approaches:1)  Save the state of the control in the worksheet custom metadata. This  method will work in versions 13, 14 and 15, but not in versions 11 or  earlier (I"m not sure about version 12).2) Save the state of the control in a textbox. This will work in all versions 11 and later, and maybe some earlier versions too.There are some things to be aware of when using them.Firstly,  in version 11 if the result of calling a function is not displayed, and  it's also not assigned to any variable, Mathcad does not calculate it.  That means that if you use method 2 and put the SaveData function in a  collapsed area it will not work. In version 12 and later they removed  this optimization, and therefore it will work.For  the second method, if the Listbox is off s

When I close the worksheet I can not save a listbox selection that is dependent on a previous listbox selection. The first listbox I was able to save the selection using the Metadata , but I could not figure out how to get it to work with the second list box.

Hello All,I am running my program for a few thousand cases. Unfortunately when one case has error, the program stops on that case. How can I address the program to jump over the erroneous cases and continue the calculation? Another question: is it possible to find out about the progression, for example how many cases has been left or required time estimation? Thank you.

Hi all,This should be a simple problem to solve for anyone with experience with Mathcad, I wish I had the patience to figure it out for myself, but I don't.I have an asset list made up of thousands of item numbers and there associated item costs, from this list I have been given a selection of item numbers of which I would like to determine there costs.Could anyone provide me with a programme where I can input the list item numbers and their costs will automatically be found, im sure similar questions have been asked, so possibly you could direct me to link.Much appreciated,James

Hi all,How can change this figur to be a scalar

Hello,How can I randomly select an element of a matrix ?

I recently got a new PC running Windows8.1. I used to run Mcad v11 on an XP machine which worked perfectly. It installs on the Win8.1 machine but doesn't run. In researching this I've found numerous postings in this forum about problems with "Prime" and Mcad v15 (evidently the last of the old Mathcad products) not being compatible with Win8.1 and/or not being able to run the old .mcd documents. I'm at a loss what to make of all this. I have 20 years of Matchcad documents that are currently useless. Does PTC have a recommended migration path from Mcad v11 to one of its current products (that works with Win8.1 and dosen't cost USD1,600?).

mu=0.2, 0.25, ..1tw(mu)>>> this mean is that tw(0.2)=19.54, tw(0.25)=15.86.....and "c" is also including mu.it means c(mu). c(0.2)=689.23, c(0.25)=662.54....I want to express like upper.Is it possible?

Can someone please explainwhich eigen vector mathcad has gave me as there are infinite number of eigenvectors?

The animation belongs to this thread here http://communities.ptc.com/message/263351#263351   Main goal was to avoid that Mathcad eats up all memory when the animation is made. Solution seems to be to represent the pic as a plain matrix as opposed to a nested vector. See the aforementioned discussion for further details and the Mathcad 15 worksheet itself.   Unfortunately this Flash video here is mediocre in quality compared to the original AVI file which Mathcad created.     Unable to play video.

Hello everyone, i hope all are having a great day.I started this discussion because im having a little problem solving a system of 2 ordinary diff eqs.Im not defining a function for t or x because theres not a way to put this in function of w.Also I dont know if i define w with a random numer and t and x with random functions would affect the final result. I just want to solve the differential eqs. I defined r(w) for example for simplicity. The problem im trying to solve is for chemical engineering. Its about solving the mass and heat differnetial eq simultaneously. Heres the document. Thanks for your time

I just got Mathcad roughly a few days ago and I need to run a dB and spectral analysis on a .wav file I recorded. I am brand new to this software and don't know where to start. If anyone can help or lead me in the right direction, that'd be awesome.Erik

Hello,I'm using the find function to find 9 variable with 9 equations. Each of the equations equal zero thus mathcad finds zero as an answer. There should be another answer. I know the find fuction will find the closes answer to the guesses but changing the guesses doesn't make much difference. I tried to set that the variable are not equal to zero but that didn't change anything. The system is working, if I set one of the equations equals 1, I get 9 non-zero answers. If anyone has a suggestion to sove the system that would be great.Thanks in advance,Kendall

Hi All,I have a problem with the scriptable drop-down menu object. If I select a value from the list, and then save the model, the set value will be forgotten by Mathcad upon opening again. And the default value (first one) is set again.Can this behavior by any method be changed?Thanks,Zsolt

I am trying to insert a program (the attached HW 2 Corrected) into another program (HW 5 Part A) so that I can pull values from HW 2 and use them in HW 5. How can I do this?

Hello All I am doing a minimization of the torque in mathcad and the solution that i am getting is heavily influenced by the guess values and each time I change the guess value a,b etc even by a small amount,it gives me a different answer. I really am not sure why it is doing that and also how am I going to rectify it.I have enclosed my worksheet . Any help would be greatly appreciated
