Mathcad

I do not use symbolic evaluation very often so I am sure I am doing something wrong.  The following expression should equal mu_0 . Why do I keep getting the same thing back? Do I need a different keyword (I tried several)  or a modifier?     

please anyone help me, ive been working this mathcad all night and suddenly this file corrupted. please anyone help mee. the deadline is near:(( helpp

I'm subtracting 2 temperatures. But Mathcad gives an unexpected answer: ΔT should equal 280°F.  

I try to replicate the example from  Example: Polynomial Interpolation (ptc.com) How Ian I plot the red error bars?

I have an array, and I need to create another array, and calculate the successive average of the numbers as I move along the first array. For instance, the average of 1st & 2nd, then the average of 1st,2nd, and 3rd, etc. till end of the array   Below some more explanation, including my attempt, but I could not reach what I am looking for. I appreciate your help... Thanks    

Hi everyone, When I want to put a variable in an Excel-file, but with non standard units, for example mm instead of meters, I simply divide it in the input field (see example).  But what about a temperature? I have tried different ways but without success. It always comes out as Kelvin.  I would like Celsius °C.   Basically the question is: how do I "adimensionalize" a temperature, that is reduce the value of temperature to a simple number, without units?   Thanks a lot in advance Best regards Claudio

I am struggling with how the Combobox works and its capabilities.I created two combo boxes, and I could populate some variables using the first combo box, but I also need to be able to change the results based on a selection from the second combo boxHow can I do that?Attached is the Mathcad sheet in prime 7

I have a task to make the code in the left as written in the right but I have an error as attached appreciate if anyone can help.  

Hi all 😀 I have a data group from excel to understand: the 1st column is : Torque the 2 column is : Position the 3 column velocity: Torque   If i make a drawing with Torque (vertical Y axis)  and position (horizontal  X axis), i have this:   I see  i have periodic data : in position , approximately from 50 to 2250 milimeter. this is OK, the data relate to a cylinder which makes round trips   My problem:   How to extract data in new matrix wich include only data for one stroke: submatrix for positionning 50 to 2250 and submatrix for positionning 2250 to 50   and that for the 5 back and forth   I want to make a drawing for forth (torque and velocity) and back (torque and velocity)     Thanks

Dear Expert MathCAD Prime Users,While I am doing my assignment of Reinforcement Concrete Column Design I have a problem when I reached design axial compressive  I can not find the Value of a as you can see in my attached file in MathCAD Prime 7.0. The error message is "The function for the end points of the interval must be at opposite signs".  As I mentioned problem, I would like you to show me how to fix  this issue in order I can make a Column Interaction Diagram.I am looking forward for your help and recommend. Thank you!

There are three random points on the plane through which an arc of a parabola and a similar arc of a catenary pass. What is the probability that the length of the parabola's arc will be greater than the length of the catenary's arc??

Hello friends, I have to calculate a beam on elastic basis by the finite element method for my master thesis, I do not understand why there is an error for plotting the graph.I attached the file.Really need help because the deadline for submitting the thesis is Friday, May 28    

Hi, I don't understand what is happening here. I have a range of resistances I put into a variable. Then I just want each solution using the basic voltage divider fuctionfunction. Thank you  

Good day PTC Community!   I was wondering if someone could help me resolve my issue with the product. I tried the symbolic solve for an equation and it was amazing. I got stuck though. I was planning to use the value solved from the equation I made inside the worksheet and use it for other formulas. The problem is I can't extract it, it just prompts me "missing term or expression." Was what I'm doing wrong? or are there any workaround I should change in order to achieve extracting the variable solved?   Thanks in advance!

Hello all   From the shortcut list of Mathcad, shift+space can append an extra column to the matrix. However, I found that it doesn't work for my Mathcad Prime 7.0.   Does anyone know how to fix it?   Btw, pressing shift+enter to append an extra row to the matrix can work in my computer.       Thanks!  

Hi,   Can I use solve block inside a program loop? For example, it may be useful if I need to scan all the possible solution of Find(var1,var2,...).   Many thanks S

Hello!   I want to solve three equations symbolically to check tabulated data. How can this be done? Should I use a solve block or are there any other techniques? Please, take a look at the attached Mathcad Prime 6 sheet.   Best regards, Sergey

I have referenced excel UB steel table and used Vector command so that I can use properties values for calculation. its easier such that I only have to change row number to select a different UB.   I use properties to calculate bending capacity (output as vector)  and compare with know demand (typed scalar values), I get errors.  How do i convert 1x1 vector answers with typed scalar values such that "all values are scalar" for checks" ?    

I'm trying to iterate over a matrix and for some reason I can't seem to generate the new matrix. It just spits out the last value of the iteration. Looking at other posts I think I have something wrong with the indices of the matrix, but I can't quite figure it out.    

I have the following equations and i am trying to ge the values for b2 and D2. I have all the other necessary values but i cannot get to solve this. Have i mistyped the root equation?I tried with the find function too.  

Take the following 2 variables: How do I use Mathcad to find the combination of x and y that minimizes g? Is it possible to do this while keeping a and g separate? Please try to make a solution easy for a Mathcad newbie to understand  

I've been scouring the forums for a while now and I'm starting to come to the conclusion that either my question is so simple that nobody else needs to ask how to do it or that it just can't be done. Put simply, I'm trying to find out how I can get MathCAD (using Prime 4.0) to return the highest or lowest result of a function given a list of possible input variables. For example, if I have a simple function: f(x,y) = x + y^2 and a list of possible values for x and y: x = [3, -6, 2] y = [2, 3, -3] How can I get MathCAD to output the largest (11) or smallest (-2) result?

Node List Tolerance Analysis: Enhancing SPICE Capabilities with Mathcadby Robert BoydHardcover: 352 pagesPublisher: CRC Press (March 6, 2006)Language: EnglishISBN-10: 0849370280ISBN-13: 978-0849370281Developed at UC Berkeley more than two decades ago, SPICE software is the tool of choice for performing nominal analysis for electronic circuits. However, attempts to use SPICE for worst-case analysis (WCA) reveal several shortcomings, including: a 400-sample limit for Monte Carlo Analysis (MCA); lack of Rot-Sum-Square (RSS) analysis, asymmetric component tolerances, Fast MCA, or AC sensitivity capability; no single-run method of tolerancing inputs; and no predefined beta (skewed) or bimodal (gapped) distributions for MCA. While several commercial versions of SPICE may have corrected some of these limitations, they still remain rather expensive.Based on extensive experience in WCA, Node List Tolerance Analysis: Enhancing SPICE Capabilities with Mathcad presents software methods that overco

Hi,   I'm using Mathcad 15 and I'm having problem in using solve block. What I'm trying to get is to find the values of PM.guess that will satisfy the LF.sum=1.   Appreciate if you can let me know how to fix this.   Thanks.

I use Prime 5 for a system of nested program modules. Normally it works, but im some cases an unexplainable error occurs with embedded matrices. Description in attached PDF-File. Who has knowledge to solve this problem? Guenther P.
