Mathcad

Here's what I found in my pantry!Happy New Year!

The best gift for me from Santa is Animation tool in Mathcad Prime! (Prime 10 I hope) My New Year's Story.I don't believe in superstitions like jinxing a person, but...I ran skiing early in the morning on January 1st. A grandmother was walking towards the park and said: "What a fine fellow you are! They are still sleeping, everyone has a headache after yesterday's drinking. And you are skiing!"I went 100 meters, fell and broke my skis! I returned home on foot - the Mathcad does not work! Need to reinstall!

I solved the equation, but I did not like the answer in form. I expected I decided to try the vaunted artificial intelligence portal. Here is what I got. I immediately remembered the sensational story about artificial intelligence, which was instructed to broadcast a football match instead of a human TV-operator. The task was quite simple - to point the TV camera directly at a soccer ball - a smooth round object moving across the field. So, at some point, this artificial intelligence lost the ball, began to look for it and... captured the bald head of the referee, who was running around the field. So TV viewers - football fans until the end of the match had the opportunity to admire the bald referee.  

I am a beginner. When I try to solve a  differential equation problem, the "simplify" tool can not recognize the Sin(t)^2+Cos(t)^2=1. I have to simplify the equation manually. The attach file shows how I do this now. Is there a solution that Mathcad can handle the identity relation Sin(t)^2+Cos(t)^2=1.?

How do i get rid of this warning message from prime  

I'm very new to Mathcad, but getting the hang of it.  I admit, plotting eludes me.  I'm trying to plot one column of data against another in an X-Y plot.  I just came across this post that explains you can't do this.https://community.ptc.com/t5/Mathcad/Needs-help-with-Plotting/m-p/273538#M106881 If I understand correctly, I can't plot a vector over a range.  Good.  I don't want to.  I already have two vectors (at least I think so), but when I try to plot them, I only get the first and last data point. Seems like the Chart function works well.  I have really tried to use the PTC Help, and I have found it really lacking for the beginner.  Any suggestions on other resources? Many of my datasets and use cases are simply a range of X and Y data.  I may have multiples of each, x1 vs y1, x2 vs y2, etc, all plotted on the same X-Y plot.  My goal is to plot several curves, each with their own X-Y pairs.   Do I need

Hi all, Please suggest, how to do goas seek  in the below attached calculation - mathcad prime 3.1

Unless I missing where it is, I think this forum would benefit from a dedicated, user-defined (UD) functions-only sub-forum.  Generally, the poster would link a topic of discussion back to the main forum for discussion. That way, the UDF sub-forum doesn't get loaded up with discussion.  It make solving some problems quicker by searching an existing UDF. I have many UDF's that I would like to share but just dropping these in here makes no sense.   Regards

On the occasion of the turn of the year, a four-leaf clover/shamrock is shown in the attached file (Mathcad 14) as a lucky charm. Unfortunately, I can't color the area enclosed by the contour. How can this be done?Kind regards, Alfred Flasshaar

I've written a function C with 2 inputs: a scalar and a vector; and 1 output: a vector. When I evaluate the function for a certain input there is no problem. However, when I try to compute the Jacobian of the function I get the following error: "The array index is invalid. The index must be an integer, not less than ORIGIN, and not greater than the last element."Strangely, when I get rid of the two bottom entries of the output vector of the function C, I get no such error, it produces the Jacobian matrix one would expect it to. This leads me to believe that the issue is in q_3. (I have made sure that 3 is no subscript but an index)Can anyone tell me what the issue here is?

I have a Mathcad file where many of the XY plots get larger when I open the file.  If I drag the plot handle to scale them back to their normal size, they get large again the next time I open the file.  This started happening with Mathcad Prime 8, and it only happens to one file, so far.  The left upper corner of each plot remains fixed, its the bottom right corner that changes location.  There are many plots in this file, and it is getting old having to resize them all each time I open the file.  These are the embedded plots, not the Chart Components.  This file is being opened from one computer.

Hello, I am evaluating Mathcad Prime 8s file converter capabilities through the express trial to convert 14 and 15 files. The converter tab is grayed out and I cannot click it. Any suggestions as to why? 

Between Christmas and New Year's I want to "play" with curves on graphs in Mathcad 14. I am particularly interested in the graphical representation of the Sici spiral (or named after Nielsen). It is represented parameterized in the Cartesian x-y coordinate system by x=Si(t) and y=Ci(t) with t>0. The Si and Ci functions are found in Mathcad on the f(x) menu. But they don't work in the diagram, even though I followed the instructions from the "Help". That's why I didn't attach a test file here. What am I doing wrong?Kind regards, Alfred Flasshaar

Hi experts, Can Mathcad help us arrange the equation from what I give?for example,the yellow parts are I know, I want to use these conditions to solve and get the green part, I know how to calculate by hand, but I would like to know if I can use Mathcad to do the same thing.if it could, could you tell me what to do, thanks?  

After migrating from MathCad 15.0 to MathCad Prime 8.0, I have a matrix in one sheet formatting exactly as I want it like this:However, in a very similar sheet, also migrated to Prime 8.0, the format has changed to this:The matrix will not display if I attempt to move the "ft" unit outside the matrix.  It is not a big deal for something small like this, but for a larger matrix, as below, it becomes cumbersome to get it to print.The matrix here is built the same way as the first image using the "stack" and "augment" functions, and the error message that pops if I attempt to format like the first image is "This value must be a scaler or a matrix." What can I do to format a matrix to get rid of the units for each individual value, and apply it to the overall matrix as I have in the very first image, just like MathCad 15.0 used to do? 

Dear Experts,I would like to ask for some problems of my performing Mathcad Prime of creating Circle Column Under Combined Axial Load-(Pu,Mu). I can not plot the Interaction Moment diagram, I already tried to find the mistakes which could be made in the equation, but I still can not solve it by my own.Since I am the beginner of using Mathcad Prime I really need help from all the professional users.I would be really appreciated for your help.PS: you can find the attached file below.Thank you!

Interior grazing problem - Closed form Solution published 18th Feb 2020 - by  Ingo Ullisch     Can Mathcad do it symbolically?     Find the value of r so that the white area is equal to half the sum of the white and red area.  

How do I export XYZ data from CreateMesh? I am exporting data from a Mathcad Prime 3D surface plot to a graphics program which will allow me to color code the surface based upon the Z values.

I have to identical equations using a square root (flow calculation).  If I use the "psf" units for lbm/ft^2, the radical doesn't evaluate the squared units correctly.  But if I force the units to be lbm/ft^2 under the radical, then the expression evaluates correctly to lb/s; mass flow.   I don't understand why this doesn't evaluate correctly.  Is there a way to make this more robust? See attached.

Hi, Everyone.From the following:   The Question 1: How to Rotate A around BC-axis with angle t ?The Question 2: How to Rotate B around CD-axis with angle t ?   Thanks in advance for your time and help.Best Regards.Loi.  

Hi guys,  I just installed MathCad 8.0 and tried to give an value to F. Every time i tried to do it i am facing an error that i will put the video and photo of this below. I tried to figure out what is wrong with program and  I have repeatedly repaired .net framework, activated old .net framework versions from program properties, installed updates and nothing changed. When that didn't happen, I formatted the computer and reinstalled all the drivers from scratch, still nothing changed. I leave the video, screenshot and .log file below. My System Specs:Asus Rog Strix G15 G513QR16GB Single ChannelAMD Ryzen 5900HXNvidia RTX 3070I would be very glad if you help.          (view in My Videos)

Hello everyone,I am a complete beginner in MathCAD and would really appreciate if somebody would help me define this with the values I provided. I tried to define the function but it just wouldn't work and I'm not sure what I'm doing wrong.     

I have seen compound IF statements that evaluate numerical values.  e.g.  if (a=1,2,3) How can I construct a compound IF statement where the variable being evaluated is text?  I want the IF loop to run if the text value Fault is A or B. e.g.  if (Fault="A", "B")  thanks,relayman p.s. Prime 8

I have that issue. Mathcad prime 8.0, excel 365 64-bit. Does anyone know why this happens? Thanks in advance.

As per the original post.    Hi VladimirN,   I am currently using Mathcad Prime 8.0.0.0 with a trial license. I am having an issue with the Excel component and am receiving the error mentioned in the article. However, I do not have permission to access the file as I am on a trial license. Would you be able to recommend any possible solutions? I am using Office 365 and have updated to the most recent version. I have also tried restarting my computer and have tried the Excel component on multiple worksheets with the same error.   Thanks!
