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.

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.  

In February 2021, we will receive Mathcad Prime 7. I am betting $ 100 (8000 rubles) for the animation in the new version of the package. I am betting $ 70 for the fact that the new version of the package will be able to show dll functions in the function window. I am betting $ 50 for the fact that the new version of the package will be able to link to Mathcad files on the Internet. What money would you like to put on what old and new opportunities?

EDIT - I figured it out. Nevermind.  Can someone help with this?  I don't understand why the 'x' variable is undefined.  Any help would be greatly appreciated

Hi all    what is best way to get mathcad to reference todays date?   I want to add a function that removes functionality of the sheet after day 6 months should another user try to access it. So will write a statement like the following    If todays date is > 01/01/2022 then etc...    

Hi, I am trying to calculate n(variable) into the formula, but I am only getting the last value. How Can I change that? so i get all the values? Thanks

I want to perform below operations on arrays of 100000 rows. I used for loop and mathcad got hanged. Is there any other ways to perform these operations? Go1 and Go2 are arrays of 10000 rows. The below code is of matlab and I want to write similar code in mathcad if ( abs( Go1 - Go2 ) > 1.0 / ( RMAX + 700000 ) )Rp = ( 1 + r2 - r1 - ( R2t * Go1 - R2b * Go2 ) ) / ( Go1 - Go2 ) - ( R0 + R1 );Rp = abs(Rp);x1 = +( R0 + R1 + R2t + Rp ) .* Go1 + r1;y2 = -( R0 + R1 + R2b + Rp ) .* Go2 - r2;elseRp = ( 1 + r2 - r1 ) / ( 2 * Go1 ) - ( R0 + R1 + ( R2t + R2b ) / 2 );Rp = abs(Rp);if ( Go1 < 0.5 / ( RMAX + 700000 ) ); Rp = RMAX; endx1 = 0.5 * ( 1 + r1 + r2 + Go1 * ( R2t - R2b ) );y2 = 1 - x1;

  Hi, i would like to have and increasing Range from 3.3 to 8 with an increment of 0.1. When i try 3.3,0.1..8 i will get this range values must defined with sequential values. How can i fix this? Thanks.  

Hi all, I am trying to plot the amplitude spectra( or Fourier transform) of a one cycle sine wave i.e sin(t)*u(t)-u(t-2*pi), where u(t) represents a Heaviside function.   1-I found the Fourier transform of this using integration. However, when f(t) * e^..... is put in the symbolic arrow does not give any answer and merely states the same. When sin(t)*e^-1i*w*t is integrated the symbolic gives the correct answer but why does it not work when f(t) is used.   2-Second problem, I want to plot this fairly simple function. The problem is mathcad is saying the real part is around 0.075 according to the graph. It should be 0,0. The imaginary part should be 0,-3.141... however mathcad is plotting 1,-3.141.... What is going on? The file is attached. Prime 6 was used

Hello,I have a circular symmetry system. A physical quantity defined in the circular section of such a system is defined by a function of the two polar variables r and φ. How to have the graph of this surface using CreateMesh () and pol2xy ()? I find some difficulties, maybe trying and trying again I succeed. But I would like your suggestion so as not to waste time. The function, in polar coordinates, is for example F (r, φ) = Jn (1,0.383r) cos (φ).

I cant believe mathcad 15 information is so poor i have to ask this How do you define an ANGLE!!! Not degrees C or F or K   I want to define a number like 50 degrees as in the angle 50 degrees!!! Why is everything in this program so hard when it doesn't have to be

buenos días.   como puedo extraer los valores automáticamente, 

Hi all I have a problem whereby I need to multiply one table by the other, I want to be able to show this so the excel function isn’t what I am after. I keep getting the error as highlighted below in the fourth column     Mast load is defined as - 1.538x10^4 N Boom Load is defined as - 5.713x10^3 N EW weight as - 227 N Cantilever 1 as - 1.4x10^3N     many thanks for the possible solutions   

Hi all,  I was writing a solution guide for my engineering students and keep getting errors in my Solve Block. I have removed all the unnecessary bits, and boiled it down to just the issues I am having in my sheet. I'm trying to get the solve block to provide multiple solutions based on different conditions of the constraint equation. In my document I was able to get it to work in the first solve block (off to the side in the work space I have my initial solve block where I hardcoded the equations just as a double check) however in my solve block on the second page "determination of beam base needed to provide eq stiff..." I'm not able to condense the 6 constraint equations like I was before. I tried indexing 1-6 and kept getting errors in my "find" statement and my output was a [6x1] nested matrix of [6x1] matrices.    TLDR: trying to index a solve block instead of hardwriting eqtns
