I have two complex number variables. The results of the sum of the inverse of the two complex variables are good but when I simplified it to product over sum, the result are not the same. Is there something wrong with my syntax on the product over sum? See attached "complex product over sum.mcdx". Thanks.

Continuing from Part 3B. Part 3C is the solved examples and solved problems for the RLC Higher Order Circuits. Relevant notes in Parts 3A and 3B. Note: Number of solved examples and problems are high. They try to cover as much areas of the RLC higher order circuits. Any errors the student/engineer should be able to correct with little or some effort. Contents: Section 1 solved examples and problems correspond to Part 3A and 3B notes. Section 2 solved example are the same for the transfer functions in RLC circuits though these are from a Controls textbook. Section 3 problem is a discussion question the solution provided is more toward looking at the solution from multiple perspectives.   At present for students in Electric Circuits 1 course there is adequate material provided here for the first semester course. Usually some of the material here runs into the early 2nd semester course.   There is plan for a Part 4 this will be in coming months, 3 at least, covering the rem

Hello,   I am currently doing my homework in Mathcad. I woould like to know if I can do more than one question in one worksheet. If it's possible, how do I separate the defined variables of one question from another?   Best regards, Goodluck.

When I try to install the license I get Access to the path ........... is denied.I have tried putting it in several different drives.Help!

The program was uninstalled and when I wanted to work I noticed that it no longer exists in the list of programs.I can't install learning Mathcad either

First time poster, casual user of MathCAD Prime 6.0, and have a question regarding setting up an equation that has multiple variable inputs (X = 1....100, 10; Y = 2...12, 2; Z.....) and present a table of the input versus output results for the given inputs.     The equation is pretty simple but I'm struggling to figure out 1) what I am missing to make it work and 2) to display a table that would show those inputs versus the output.  Its probably something simple but it's eluding me.      

Im relatively new to mathcad and I'm trying to plot the stress in a curved beam as a function of the distnace r from the center of rotation. I get this message:  Value must be a scalar or a matrix. I thought i made x a range variable.

Buenos Días, no puedo activar mi Mathcad 6.0.0 con el archivo de solicitud de licencia que me proporcionaron en mi correo, no logro ubicar el código de producto en el mismo. ¿Qué debo hacer para activar todas las funciones de mi mathcad?

my license will not be accepted

I am unable to login, and try the 30days trial.

  Hello Everyone.How to plot a triangle of XY-plane in 3-D FOR SURFACE PLOT IN ORDER TO "FILL (COLOR) SURFACE" TO THAT TRIANGLE ?Thanks in advance for your time and help.  Best Regards.

Seriously!?!?!?!   You can't highlight a variable in a symbolic equation and just solve for it? It is ridiculous that it is easier to rearrange the equation by hand and solve without the help of Mathcad!!!   What is the point?   15 versions of a wonderful working software package and you just threw it out. I hope it makes you lots of money because you obviously don't care about long term customers.   SMath looks better and better.    Of course, all of this said, knowing that no one at PTC cares one little bit!

Hi, I´m translating some matlab code into a Mathcad, I need to overwrite indices in vectors   Matlab does it like this: f_site 23x1 Vector idx 13x1 Vector wich has the indices i need to overwrite. f_site(idx)=...   In Mathcad I cant do it like this   Thank u 

I'm using it to do my assignment in University Sains Malaysia

Hi, I´m translating some matlab codes to mathcad  and I have had problems with the function Find. Matab: Vs30= Value Vlin= Vector 23x1 idx = find(Vs30 < V_lin);   In Mathcad it says that idx is undefined.     It should return a vector 23x1   Please help me, Thank u !  

The plot menu bar in Prime gives three choices for plot background: white transparent paper color How do you change the paper color?

Hello Everyone.From : How to plot a cube ?Thanks in advance for your time and help.Regards.

Hello guys,   please help me to solve this problem. I would like to plot the magnitude and phase over a logarithmic frequency axis for a given transfer function. In the first picture I create the transfer function with symbolic mathematics. In the second picture I declare some parameters (but without units !) and I tried to plot the magnitude ...   The single point in the graph is unclear to me with a value of approx. 20 ?? All the values on the y-axis must be < 1 ... or < 0db   Thanks in advance      

I have two data sets that I can curve fit to get polynomial equations for. These are 2D data sets for temperatures of 23C nd 65C. I want to find the equation of a curve at 52C based on these two curves. I could interpolate between each value and generate a new data set piece by piece, but hopefully there is a better solution? Any help woudl be greatly appreciated. The data sets are attached in Prime 6.0   Thanks in advance!

I was asked to:  Solve for all positions of the designed mechanism, with an increment of 5o the driver-dyad crank angle. Specifically, calculate angular positions for the input, coupler, and output links, as well as the coordinates of the point P (hint: first find the set of input link angles as outputs of the driver dyad, then repeat the analysis with the set of input angles as inputs to the mechanism designed in part 1).  Plot angular positions as a function of the driver-dyad crank angle in one cycle.  Plot the positions of the point P in two ways: first, plot each as a function of input angle; second, plot the trajectory of the point P on the x-y plane.  Assume that the angular position of the driver-dyad crank is varied with a constant speed of 5 rpm. Find x and y components of the velocities and accelerations of the point P. Also find the magnitudes of total velocities and accelerations of the point P.  Plot the magnitude of the velocity of point P

I was not able to download trial version of Mathcad 15

Hello, this year in January i requested a MathCAD Student Version and received a licence file. 2 months ago my laptop had to get a fresh reinstall of Windows and now i can't get the full version of MathCAD working with the old licence file. What can I do? Thanks in advance. Matteo

I did buy a student version but I am not able to download it. My order number is 102188855813.
