Mathcad

I'm a mathcad prime 10 user. I'm writing a worksheet for a study material and design check. In manual, its calculated value is a little bit different from the equation above. I wonder how accurate with what significant figures the mathCAD prime 10 does calculation even in every single term in the equation. Plus, how can I get the more accurate result with very accurate single term in the equation?

I'm a mathcad prime 10 user. How can I get results in a column vector Q with respect to each coefficient Ai and Bi? I need to have Q1 with respect to A1, B1 and Q2 with respect to A3, B3? It doesn't really work out in method 1 and 2. The correct result should be the value in method 3 when considering Q1 only. 

Is there a way to ressign the values to a variable in mathcad programming?For example Es is 2.175 and Ec is 3.5 in a loop. Ec is fixed here and iterate Es until MEd is almost equal to MRd. If it doesn't happen then change the values of Es to 25 which is fixed and Ec iterated from 0 to 3.5 until MEd is almost equal to MRd. How to write a Mathcad program without repeating the steps.  

I generated a percentage range from 0 to 100% with a step of 5 percent. Since Mathcad did not want to concatenate two matrices generated this way using the augment function, I created a manually entered matrix. Here, a problem arose because the percentage range entered by different methods yields different results in calculations. What mechanism is behind this?  

So I was working really hard to be lazy and asked google gemini to make a formula for mathcad. It spit out some results, surprisingly, but it didn't work when I tried to paste it into mathcad prime 9.000. It showed some notation that I have never seen before and couldn't find any documentation saying that mathcad can even use it. See my picture attached. Anyone know how to use this "!" feature? Secondly I asked Gemini how to use its output and it said just copy and paste into mathcad, that didn't work, just pasted as a block of text, am I doing that wrong too? Any help is appreciated, or other better experiences using AGI?

Hi,I have been updating a Mathcad sheet and noticed that there are slight discrepancies in the results on the order of 1e-6. I tracked the source of this error and I got to this integral (shown below). There are two things I do not understand:1.- Function A and B are the same but for some reason B throws an error "this value must be an integer".2.- The integral should be equal to 1 when the upper limit is approx higher than 5. But for some reason the solution jumps from 1 to 5e-4 when the upper limit goes from 1.011e4 to 1.013e4, which is wrong. It should be 1. I am using Prime 8.0 Regards,   

Is it possible to export Mathcad sheet to XML file in version 9 prime?If so, how?Thanks 

  This month’s challenge is inspired by Dungeons and Dragons and Stranger Things. D&D involves spinning dice, which are regular convex polyhedrons. The most common dice used are d4 (tetrahedron), d6 (cube), d8 (octahedron), d10 (decahedron), d12 (dodecahedron), and d20 (icosahedron), where ‘d’ is for die and the number indicates the number of sides. In this challenge, we will focus on the Platonic solids, which are the regular polyhedrons made up of regular polygons (the lengths of each side and interior angles are equal). In other words, skip the 10-sided die. Most references define regular polyhedrons as a function of the edge length of one of the polygonal faces. In this challenge, we are defining the regular polyhedrons by the radius of the circle that circumscribes a polygonal face. Your challenge is as follows: Derive the surface area of the regular polyhedrons as a function of the radius of a circle that circumscribes a polygonal face. (Optional) Derive the formula fo

 When using the root function of Mathcad with more than two parameters, an error occurs. It seems to be a bug. Does anyone have a solution? A simplified example of this issue is printed and attached as an mcdx file. In the original Mathcad sheet where I found this error, this function is used in an advanced routine with parameters in arrays and with dimensions. This function worked fine in previous versions of Mathcad.  

Hi,New user for Prime 9 I want to customize the S N Curve (X, Y) plotso that for induced stress values corresponding life cycles to be known.how the units to be incorporated in (x, y) labelsX corresponding y value to be shown or vice versaX, Y limit values to be customized Thanks & RegardsGS 

Hi, I'm new to Mathcad. I understand the basics, but I'm struggling with how to solve the equation to find the value of xMathcad prime 09 

Hi All, We have recently carried out some testing on a system which has generated quite a bit of data on a spreadsheet. A calculation was set up to prove the original operation, but since there is now data, our client would it processed. Is there a way to obtain data from an excel spread sheet (one column), put a single value (one cell of the column), process via mathcad calculation and then export the cell to another spread sheet with the result variable desired?

I'm installing a single user, windows, MathCad 14.0 from the CD Disk with Date Code: M020. Since this was an upgrade from a previous version, the installation is asking for the "old serial number," which I don't have. I contacted PTC customer support, and they kindly generated and sent me a License Pack file. Where and how to use this file?

I want to repeat certain steps in side a program in Mathcad. Is it possible?For example in a beam cross section i will fill the bars in one layer until the spacing of the bars is not less then minimum spacing and then i will check if the design moment is less than or equal to resisting moment. If not i have to repeat certain steps and place the bars in more than one layers until the design moment is almost equal to resisting moment. I have a program to place the bars in one layer, how can i tell mathcad programming  to repeat these steps for the second and third layers?

Using Prime 9.0Hello,I have an Excel program with VBA code. When you click the "Calculate This Tab" button, it configures the input values in the designated Mathcad sheet (relative file path in cell D3) , and calculates the outputs accordingly. The point is that these values can easily be changed from Excel and the outputs are calculated based on the latest values and outputted back to Excel. The real program is working on a much larger scale, but I created a small scale version for simplicity here.The problem I am having is when trying to output a Matrix back to Excel. I have not been able to get it to work in a seamless way. One thing I have tried is writing the Matrix output to a temporary csv file and then importing the data into excel through a sub function defined in the VBA code. This sort of works, but the problem with this is that the WRITECSV() function in Mathcad does not update when I run the macro from Excel even if I assign it as an Output like the others. I have to manua

I'm using Mathcad Prime 9.0.0.0 and I need help comparing the values in 2 matrices. To be more specific, I need a program that will start with the first column and compare the values going row by row, then return the value if there is a match, and if there is not a match then move on to the next column and repeat the comparison process.   In the example matrices, Column 9 Row 4 (-1.63) should be the only value returned.

Working on linear interpolation of a coefficient from a 7x4 matrix, utilizing x and y axis ranges, Pg_Vector and R_vector respectively. From the first part of the linterp function worked perfectly for the x-axis  solutions, but the second time working on y-axis returns an incorrect answer. See attached Prime 10 file.

Let's say I have a generic system block diagram as shown above, where I have two unknown inputs generating one output based on several scaling, offset and addition blocks. M1-3 and B1-3 are known parameters that do not change. I'd like to take the derivative of of the output with respect to M1 with some known inputs as setpoints. That's easy to do with the following:My problem arises when I try and define that same equation as a function of the inputs: I can get around this issue by defining the function with ALL variables, but this is tedious and cumbersome especially as the equations grow with many more variables Is there another way to do what I am trying to do without having to define a function with every variable? I've attached my sample mathcad showing this example in detail.   

Good morning, I am starting to compile more custom functions. I thought it was possible to have these appear in the "insert function" action. However, these do not show up.  I did stumble on CustomFunctions =  to show the content. Is this possible?   This was a note from pre-Prime DLL construction: Making the function available through the Insert Function dialog box In order to make a function appear in the Insert Function dialog box, you must provide information in the file USER.XML located in the subdirectory \DOC\FUNCDOC. Each function is an entry between <function> tag. Use the <name>, <category>, and <description> tags to specify the function name, its category, and its description as they should appear in the Insert Function dialog box. Between the <params> tag, indicate the parameters the function accepts. If you create a CHM Help file for your functions, use the <help_file> tag at the top of the XML fil

Hi,Change variable a from below and look at the V2(t)...Why odesolve block is behaving like this? Is it normal?Prime 10 file attached.The expected behaviour is like a =7.              

Hi,How could be made this kind of pulse signal in Mathcad?  

In this gear design work, I want to find a suitable x1 and x2 to make the sliding rate of each gear equal or close to equalnow I was stuck here, do you mind telling me which place is wrong and how to solve this question?Really appreciate your reading and help!    

Hi everyone. I'm using Mathcad Prime 10.0. Was using 8.0 before the update. I tend to use vectorization this way before and never had a problem. Since I switched to 10.0 this way doesn't work anymore. It should be a vector or matrix but none of the operation for matrix or vector work anymore.  Let me know if there is any error on my side, Thanks for your help! 

IMPORTANT UPDATE:   I have been struggling through a file I created originally in Prime 9 that has 3 chart components. The first is a simple chart component with absolutely no modifications made to it, containing 24 curves. The second chart has 6 curves with customized legend, line styles, title, etc. The 3rd chart has 10 curves and all elements of the chart are customized heavily (chart title, legend, trace names, line type/color/thickness, axes names and tick mark font sizing on all elements, etc.). This 3rd chart continues to become corrupt after saving it - of course this is the one that needs to be published!   NOTE - Prime 10 seems to be "behaving" so far - hopefully this has been addressed in this latest version. Stay on the lookout for this issue with your chart components using Prime 9!

Hi,Why I cannot do like f2(x,y,z) as we can see the derivative result is depending on all 3 variables x, y, and z? Should be like that for f2? Prime 10
