Hello Dear Friends,How can it be solved that the phase - frequency graph of the bode diagram in Mathcad looks like the phase - frequency graph of the bode diagram in Matlab?   Calculations and graphs were made in Mathcad 15.Attached is the Mathcad 15 file with the details.Thank you.Best regards.  

Hi everybody.I started to work for a little engineering company. I think the "MathCAD Express" can help us a lot to calculate beams. My english is not perfect and I dont know what is legal with the express. Can a company legally use it for free?Thank you for your answers.Have a nice day.

I'm working with one of my professors on Mathcad to use curve fits in checking values gathered from another program. Defining unitless (but not really) temperature and pressure, I'm running into an issue where a variable in a loop I'm using is undefined. I'm feeding a pressure variable into a base 10 log function, but with no success as it complains it is undefined. Any help would be appreciated.

Dear all  I have no idea to write program for plot 2D&3D in mathcad prime  just know  + For 2D plot        X=3@5,Z=11@4 for all grid +For 3D plot         X=3@5,Z=11@4 Y=3@5 for all grid picture attachments thank you 

Hi All    We've been doing multi-element box-whisker/histogram/error-bar plots for a while in coursework and in the past it's worked well.  Recently we are no longer able to replicate the plots.   An image of a working plot is here Alas, they now look like this (note the Box of the combined histogram boxplot has collapsed to a single line (or likely one where the width of the box is simply too small to see.   This happens on multiple machines and neither I nor my students can being back the old [preferred] way.  This was working in September of 2020 (for people joining late it is now February 2021)   Ideas?   Bill Capehart SD School of Mines.

I was looking at the list of groups members have created. I noticed there wasn't one dedicated to Mathcad users. Or even one that teetered on the subject. Would you join a group for Mathcad super-users? It could be regional too, "Mathcad users of the U.K." "Russian Mathcad'ers" etc.What kind of group would you create?-BostonDan

If i have the "cBord" table, how can i generate a vector "qv", using some data colums of every table row? . The file in mathcad 15 is attached.   Thanks.

I am new to mathcad prime and unable to evaluate solve block result not sure what is wrong 

so i have two vectors.  One is a time stamp  the second is y axis data.    so for each time stamp there is a corresponding data point   I need to plot this scatterplot somehow and then find a line of best fit.    Then i need to take the integral of it.  I have tried to use the regress function and the interp function without luck. All i get are errors.  I cant find a good example online.  The is just a simple 2d plot. Good old X and Y Can someone help me with an example.  I dont understand all the parameters that regress and interp are expecting.  When i try to plot it just gives me an error. i cant post my sheet because of IP

Hello.   I am unable to find any way to change line spacing in text box/block. Is it possible? How?

I am building a program from separate debugged statements. Now I have to do it like this - enter a variable, the operator <- and expression separately.It would be very nice if this could be done with one copy with automatic replacement of operator := by operator <-.  

Hi all,   Any word on the release of Prime 7.0? I've been waiting a year to see if it finally functions and presents well enough to be able to use it in anger in our business. I guess time will tell! I only have a basic wish list:   Sort out the pixellation of Excel components when printing/pdfing. Ability to add frames to headers, footers and the main document text. This makes a great difference to the presentation quality. Until these are sorted we will have to stick with v15 and live with the slowly increasing quirks/crashes, but at least it has the functions we need to create presentable engineering calculation reports.   Anyone else in a similar boat?

Hi,I am having an issue where I can't get a range of values when I use two ranges in one equation: for hlc I am expecting a range similar to Le and v, what am I doing wrong? Thanks!  

Hello everyone, Someone knows a smarter way to draw an equilateral triangle? Thank you very much.  

Hello, dear Mathcad community!    I am working with 18 equations and I need to get the result of 18 unknowns symbolically.  I have searched through the PTC community and tutorials, but Mathcad is telling me about the error with undefined parameter in the function. Can you please help to figure that out? And is it possible to solve such many equations symbolically in Prime 3.1?

How to factorize the number by using solve block?

I had one bad mark on my math exam at school. The question was - what is the sine of 45 degrees. I immediately drew a rectangular triangle with single legs in my head and gave the answer - one divided by the root of two: the leg divided by the hypotenuse. But I heard from the teacher that the answer is wrong. The correct answer is the root of two divided by two: this is how it is written in all textbooks! And, actually, why?

Hi everyone,   I'm a newcomer to MathCAD and am stuck on a problem.   I have a vector V with n number of data and I want reduce it into a new vector V' in which the first row is the average of the values of first 70 rows from the vector V, then the next row in V' is the average of the values of next set of 70 rows in V, and so forth. I've written the problem more clearly bellow: I'm really not sure how to tackle this, so I'd be thankful for any input. Thank you in advance! Tea

Dear all  Please help me do summing data depending on Index as attachment. Thank you

Hello, I have a beam with a triangular line load. For this task I wanted to visualize the existing Mb curve using a My curve. I created this with partial functions. So far so good. As a further step in my task, I wanted to use Mathcad 15.0 to determine the location of the greatest bending moment. From a purely mathematical point of view, this corresponds to zeroing the 1st derivative (lateral force). Everything is clear from the logical understanding to the procedure. Unfortunately, from this point on it does not work completely smoothly and without problems. Because I have created a new definition with the derivation and function including the run variable specified for the derivation. Then I wanted to use the symbolic commands "Coefficients" to output the existing values ​​and to have the 2 possible zeros displayed again with the additional "Set to zero" function. Unfortunately, when performing these steps, I always get the error message that there is "more than one independent varia

I'm trying to create a calc where the answer is a design factor. The calc works fine when just using numbers, but when I try to use a value from earlier in the sheet I get the 'units are not compatible message'. Would appreciate any help on this, thanks.

As most of the more experienced users of this board will recall, I am a very long-time user of Mathcad (I think it goes back to Mathcad 4!). You may also recall my significant reluctance to use and/or deploy Mathcad Prime...of any version to date, for the countless reasons we've all shared here. Even given this history, I am to a point where the topic has arisen within my division & company to consider deployment of Mathcad Prime ("Why haven't we moved to the newest version?"). Through all of this, I have given kudos to PTC for a number of advantages from newer features within the Prime family (yes there are some very nice capabilities we don't have in v15). Because of the continued, significant need to keep a foot heavily planted in Mathcad v15 world along with now a desire to begin considering a migration to (or inclusion of) Prime, I'd like to know if anybody has deployed BOTH codes to their community. If you have, how have you accomplished this? Was it worth it (i.e. would

Hello, I am struggling in implementing a problem that  implements Newton's method to solve a system of two non-linear equations: 𝑥^4−𝑦𝑥^3=1 6cos(𝑥+1)−𝑦=2 I am trying to implement  𝑥^(𝑛+1)=𝑥^(𝑛)−𝐽(𝑥(𝑛))−1∙𝐹(𝑥^(𝑛))with 𝐽(𝑥^(𝑛))^−1is the evaluation of the inverse of the Jacobian matrix and 𝐹(𝑥(𝑛))is the output of the equations. I have done most of the iteration work I believe in the function but I am stuck on how to manipulate the values to come up with the intersection points of these two functions.   Here is my code:

I am a wxMaxima user and shifted to Mathcad recently on the suggestion of my friend. I am testing the software and am being amazed by the easiness. But I found its symbolic engine not up to the mark (let's delay this discussion for some other post). Currently, I am testing the plotting feature of Mathcad. It has become my habit to test every new software I use with these commands just to see the beauty of math and the power of that software.  I am not able to figure out the way from the online help available about this topic and therefore am asking in this community forum.   The first animated plot that I want to create is of a spring moving. The wxMaxima code for this is shown below. This creates a 3D plot of a spring that is stretching and expanding.   The second animated plot that I want to create is a vibrating sheet. The wxMaxima code for this is shown below. The animated gif is shown below. Please also mention the method in which 2D plots can be animated. Also,
