Hi. How can I solve for this ?

Hello everyone I try to draw a function several times on the same graph, but with a displacement "dx" on the axis of the abscissa as shown in the attached document. I hope you can help me.

How can a eliminate the numbers after the decimal without rounding off it. Please do help    

Hello Everyone,  I am an electronics engineer who has just started with Mathcad v15. I work on a sheet which calculates total power dissipation in a power supply. I have many input variables which help me to get the desired information - total power dissipation (Ptot) and predicted efficiency (Eff). So far, the calculation sheet works well.   The struggle: Now, I would like to vary some input parameters and see in a plot how total efficiency change. For example, I want a plot with Iout on the x-axis and Eff on the y-axis. I have already spent half a day by googling but could not come up with a solution. Could someone review the sheet and come with a proposal how to make a Eff vs Iout plot, please? I expect that I need to somehow turn my equation into a function (numerical vs symbolic engine).   PS: A tip what to search on the forum will do too.I am not lazy 🙂   Best Regards, Jiri

  Hello, Everyone.   From :     Thanks in advance.

I need to solve these ODEs using MathCAD Prime 2.0. Image of the ODEs is attached. With initial and end boundary conditions: vf (0)= 0.2 xf (0)= 0.011 Pf (0.34 @ end/exit) = 1.01*10^5 Tf (0) = 80   Thanks!

When I try to insert a control (such as a text box or list box) in Mathcad 15.0 nothing happens. I was able to do this in MC14, and worksheets created in MC14 or saved in MC 15 with these items work correctly. MC15 just can't create them. Is this a known bug in MC15?

Is their more smart way to solve ODE question No. 2 by Mathcad Prime 4.0? My answer is attached. T.Tokoro.      

Hi. In my book about mathcad i have a formula (upper image), and i was try write this formula in mathcad (lower image). But result does not match. Maybe i lose some arguments?    

  Hello, Everyone. From :    Thanks in advance.

Is there an option that would allow to hide the unsightly "Collapsed Region" lines when printing a report from Mathcad?Haven't found one and now have to fit the collapsed regions on their own pages which can then be removed from the printout. Was hoping for something less cumbersome.Maybe the lines show as deletable images if exporting to Word? But would rather avoid the Word editing step if at all possible, and go directly to PDF.Thank you.

  Hello, Everyone.     Thanks in advance.

How is the following possible in Mathcad?  I can not even type (S2 = S1) within the equation. Thanks.

  Hello, Everyone.   From :     Thanks in advance.

Tring to use a matrix to calculate velocity with 360 degrees, manual angle setting gives the correct velocities but the matrix does not give the same values and they change depending on the size of the matrix. I have tried several things to get it to work but no luck.

Hello,       I have used Mathcad to plot an image of a Gaussian beam I obtained from a camera. Obviously the camera has pixels, each with its own pixel value that represents part of the Gaussian beams intensity. When I plot this intensity image in a 3D plot in Mathcad it displays a plot in the same dimensions as the camera image, but the data has been 'smoothed' out and now represents a more ideal Gaussian beam profile (rather than a pixelised one seen on the camera image).    My questions are: How is this smoothing of the camera image done? How representative is this of the actual beam incident on the camera?     I have attached pictures of the camera image and the Mathcad contour plot (from 3D plot). I am unable to provide a data sheet as my workplace prohibits it. All I have done is import the saved data of the camera image and asked Mathcad to display it using a 3D plot.  I am new to Mathcad, so understanding how this works will be a gre

I decided to start a new topic about the future version 5.0. Based on the new timeline (was dated February 2017), the release is scheduled for early 2018 year. And there is nothing new about the planned features of the 5.0 release.         Old thread "PTC Mathcad Prime Roadmap (2015/2016 update)": https://community.ptc.com/t5/PTC-Mathcad-Blog/PTC-Mathcad-Prime-Roadmap-2015-2016-update/ba-p/446448

Hi,   I'm using mathcad prime, and I'm working with a beam subjected to a uniform distributed load, supported at two points.   I'm managed to calculate Reactions and also plot Shear and Moment.   I'm having trouble finding minimum/maximum values for my Shear and Moments, I tried to use the max function but  did not succeeded.   Any help on how can I get the maximum and minimum values of the referred functions within the range of xx?

Hi all,   First time user so unaware if this is the kind of problem that can be solved using this forum.   However, what I am looking to do is to create a template for bearings design and sizing on electric motors. The template will allow variables/inputs to be inserted by the user and it to then give an output of what type of bearing should be used (plain/rolling element etc.) for this type of electric motor and what size of bearings should be used.   The kind of inputs I have had in mind are load, motion, lifespan and speed but open to suggestions.   I have struggled to find info on any bearing design standards or motor design standards that would help.   Any help with this matter is greatly appreciated.   Joe

Gents,   Hope all of you are good. I have one more question, and as always this kind of stuff get complex only when I do it.  Under procedure I get some values in zero, which then needs to be divided. However in my case it would simply mean that this portion of the result shall not influence and it needs to get out of the equation (simply wave effect is not applicable after certain depth).    Please note, this attached sheet is simplified to show what I need to do, original one is 15 pages so far.    So I'm trying to make some kind of loop which shall state if there is no valid result from above step, return 1.    Looked throe the manual and this forum, but can't find nothing, It looks like I runned into software limitation (due to fact that is not logical what I want to do)..   Thank you in advance.

I am preparing a Mathcad V15 computation for Electric Fields at given points across a power line corridor. Long ago I created one with a limited number of circuits (1) and wires (5) that processes correctly. The problem requires consideration of the effects of x energized wires at each point k in the corridor and time position b.  The process is to compute charge and then electric field from each of x wires at each k over all b, sum over all x wires, then select the maximum values of EX and EY at each k. My early slim computation used brute force to eliminate the x dimension of wires.  So I would create QM1 = QM[1 for the charge say and have a function QM1[b,k]. This requires creating a separate equation for each QM, one per wire.  My programming effort is aimed at allowing variable input via a matrix and automatically processing the necessary equations to compute an answer.  My problem is getting the new programs to work through the three variables. &nbsp

Greetings. The code (painted red on the worksheet) is delayed when I change the data, I would like to know if there is any way to lighten it.   Also, I do not know if there is any way to create a function that when entering the data (painted with blue in the worksheet), get the results "Reactions" (painted in yellow on the worksheet) -that would help me a lot - or also some way to keep the code waiting until you enter the data.   The code that I programmed is to find the "fixed end moments" of distributed loads, until now I have only checked it with the cases that appear in the sheet in screenshots.
