Mathcad

To all In need of some expert input. I am trying (haven’t started yet so no 1st –go mcad sheet attached yet- It will come soon!) to do the following (all standard stuff for anyone into signal processing)1. From a PSD create a time history2. Superimposed some other time profiles to the time history created in #13. Create a PSD (via FFT ) of the new time signal Thanks [Edit] attached mcad 15 file

I am using Mathcad Prime 6.0 6.0.0.0How can you make cam designs in Mathcad and than insert these files/tables into Creo?Do you have any information about this?How to make these connection to import tables in Creo coming from Mathcad.

Hello there! Can someone convert a .mcd to a .mxcd I need to open a .mcd file in Mathcad Prime 5.0.0 and it does not work. Tahank you!

Ich habe die Installation komplett abgeschlossen, jedoch kann ich die Sprache nicht von Englisch auf Deutsch umstellen. Mir wird nur die Option Englisch (bei Tools-> Preferences-> Language) angeboten.

Trying to install express after my computer was scrubbed.

The XMDC, MDC converter is greyed out and I’m not able to use this feature. How do I fix this so I can convert my file? Thanks

Hi all, My job is to find and plot the Fourier series of the wave(figure 8.png) up to a sensible n value.   Problems: 1- When I try to compute the f(t) using the symbolic engine it gives me (Error 1 and 2.png) 2- When I try to plot this, I get another error something along the lines of plot failed because of 'complex and Nans' or something along those lines.   I have attached my file and used legacy symbolic engine but still does not work.

i want to instal mathcad 15 for educational purposes

When I am trying to install Mathcad, I get to the licensing part and get an error saying "The server committed a protocol violation Section=ResponseHeader Detail=CR must be followed by LF". How do I fix this?

Description:Constructs polar plots and Nyquist stability plots for system functions, and examines how the plots can be used to design stable systems.  The polar plot example includes the method for drawing a contour of constant closed-loop magnitude.  The Nyquist plot example shows a transfer function with one pole on the imaginary axis.

Hi, How can I modify the operator so that it works correctly and not as shown in the figure? In the image what I would like is marked in red: I used a letter linked to the sword symbol (but I could have used others) because when it is used as an argument of a function in a reference file, it is sure that, in the calling program (s) (in which I will be careful not to use that symbol, linked to the sword symbol), no conflicts arise.

Hi I want to use a hexapod (gough stewart platform)  in mechanical application. The hexapode is formed with: _ 1 base plate (ground) _ 1 end effector (platform) _ 6 leg (mechanical drive effector) This system have 6 DoF for platform For build this mechanical device, I need to calculate: _ inverse kinematics : If i know the posture of platform, I find the leg lenght   (the posture is : 3 positions : dX,dY,dZ and 3 rotations : dRX,dRY,dRZ) _ Leg Forces (traction-compression only generated in leg) For start, i build the geometrical model, for this, i define a ground mark : O with coordinates 0,0,0 1) I define the hinge point of base : Ai 2) I define the hinge point of platform : Bi 3) I define the C point is the géometrical center of platform Now the leg are AiBi vector   I define a user mark The  user mark M ( 3 positions + 3 orientations) is define to mark O ( the origin of mark M is the point of interest) For moving the platform, i define a new mark Mc from M This m

Hello Dear Friends,I would like to plot the following equation in 3D Plot in the variables freq and t, but I don't realize how I could manage to fool (if possible, obviously) Mathcad 15 about 'Divide By Zero'.Or what am I wrong or do I not take into account when plotting the chart? Another thing is: ---------------------------------------------------------------------------------------------------------- Case 1:         Case 2:     Why does the second graph not display like the first? Thank you.Best regards.

  Hi, I want to know how you would show less decimals in an equation and maybe move one part down a line to better fit the A4 format.  

Hi everyone, I think for you it is a piece of cake but I have to ask you something. I would like to calculate matrix K-Lambda M and determine egenvectors W. I tried but my checks are not satisfied. The values are diagonal but they have to be around zero exept 11,22,33. I need the help what kind of functions should I use?              

Hi, I am trying to plot compute and plot the complex Fourier series of a even looking pulse wave with the mid point at the origin. First the pulse width is T/2 and then reduced to T/5. Where T is any arbitrary period.    Problems:  I have computed the Fourier series for the pulse wave, however the maximum amplitude does not match the required one. For the pulse width T/2; a 1.5 amplitude is produced which is not 1 as required. How should this be plotted, the Re and Im separately or just the modulus? I only plotted the modulus but the shift is not correct since the lowest value is not even touching the t axis.   Any response would greatly appreciated. I have attached a prime 6 sheet apologies if you don't have prime.   

hi,   i'm sure this is an easy question for a lot of you. i don't understand the help or built in examples for this topic. i have a variable i want to switch using some type of control. i can't figure out how to do it. i got the slider switch working, which is nice. but the other controls i can't figure out. i attached the matchad 15 worksheet. not interested in a prime solution, if there is one.   there are five choices for the variable z. i have just been manually typing in the choices. if you could show how this would work for as many of the controls as possible, i would appreciate it. it's something i'd like to learn how to do.   thanks

I'm working on modifying a program I am using for iteration in regards to some compressible/thermodynamics topics. I'm now modifying some isentropic relations to account for a Mach variable, but my sheet goes haywire with unitless declarations and "value must be scalar". I've attached both sheets below for comparison to how it should run and then what I want to do. Any immediate help would be appreciated.

Hey there,   I am trying to create a pulse train of period 20 ms with a pulse width of 3ms. I am trying to use a fourier transform but I have the incorrect pulse width and I would only like to display the positive amplitude from 0 to A.

Hello everyone,   I attached data file.   I have error that is "A server error occurred or the specified sheet name is invalid".   Previously, this error did not occur.What is the cause?   Thank you.  

Dear PTC Support:I am requiring my university students to install the free academic version of PTC Mathcad Express. It is such a valuable tool to perform complex computations. I provided a link to your website, but they are having difficulty installing the software. See below comments:“I have tried downloading Mathcad but I never received the link in my email. Has anyone else had trouble downloading?”“I'm having the same issue.”“I also tried emailing the address given on the website twice and have not gotten a reply yet. Robert do you have any suggestions?”“I also am having the same issue. I've tried multiple email addresses and sending them an email like you did without a response from them.”Do you have any suggestions to help students install the software? Sincerely,
