Mathcad

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

Hello, I am trying to implement a program where I can find out the "y" value for a given "x" value using Lagrange Interpolation with data points (x,y) like the ones shown below: The program should use these expressions:        

Hi all, I need some help plotting graphs. I have defined the function f(t) however Mathcad still says the function is undefined. Please provide solution. I have attached a screenshot have a look.

Hello!   Tried solving diff equations for the first time. Here is a system of gone mass through exhaust valves, in-cylinder pressure's and of function, which depends on in-cylinder pressure to constant exhaust manifold pressure ratio and i guess doesn't need any initial conditions, as mass and . The modelling "stroke" is exhaust. Every single functional relation is established in possibly attainable range, so really no ideas on how to solve this.   Odesolve worked with constant mass (with only one diff. equation of pressure) (compression and combustion strokes), so i guess all variables set correctly.   I'm waiting for any help........ But how can i provide the document for breakdown, when it is 14 pages long?   Thank you!!

How to generate random values in Mathcad exactly like randn function generates in matlab?

Hi!In the attached folder there is everything you are looking for Fourier series, and much more; The main worksheet is "Waveforms' Spectra" which takes, maybe, half an hour to analyze and graph about forty signals. But there is also a second one apart, which produces the graphs of some signals. The operation is not immediate because first of all you have to adapt the references of the single worksheets to the folder where the files are copied, it doesn't take much time. Regarding the references, see the example in the following photo:

Hi all,  I am trying to find out the Fourier series of a half rectified sinusoidal wave for up to six terms. Amplitude= V volts and period of 2pi.  For B(n) the first term should be 0.5 then 0 afterwards. However, Mathcad is giving a very small number 10^-17 but not zero. Why is this ? Second problem: When I try to integrate sin(t)*sin(nt), Mathcad should use the orthogonal trig identity to convert it into sin(1-n)t+sin(1-n)t or something along those lines. If this is not done Mathcad can't compute when n=1 because in B(n) it has n^2-1 in the denominator. This is a small problem that I can live with but the one above is a bigger one.   

Hello Dear Friends,   How can these graphs be implemented in the simplest way? The graphs are periodic, as can be seen in the figures.     Thank you.Best regards.

Which is larger?  or 

Hello Dear Friends,I'm trying to do the following:1) I have a transfer function in the z domain and I want to build a function in Mathcad to which if I give the respective transfer function in the z domain at the exit of this function to obtain the values ​​of the coefficients.2) Having at my disposal the coefficients of the transfer function in the z domain, I would like to construct a function in Mathcad that would do the inverse of point 1, namely at the exit of this function to obtain a transfer function in the z domain, ie the function from point 1.For example, the transfer function in the z domain has the degree of the numerator and the degree of the denominator equal to 3, as shown in the figure below (for simplicity). How could this be achieved?Attached is the Mathcad 15 file.Thank you.Best regards.

i dont't know how to solve an equation with constant like 'A' or 'B'   for example: x+B=A solve, x   it is available in MATHCAD 15, but not in Prime how can i realize this function?

I'm having difficulty solving for a variable in Mathcad prime 3.1Could you please let me know?Thanks

  Hi: I would like to filter the repetitive values of the vector [t]  to form the vector [q]. The file in mathcad 15 is attached.
