Introduction to poles and zeros based on notes made from Engineering Circuit Analysis, 4th ed Hyat and Kemmerly. McGrawHill.   Study notes on poles and zeros. You are welcome to correct it for yourself. Series RL circuit was straight forward but the parallel LC circuit needed more looking into by myself. Poles and Zeros continue on in Higher Order RLC circuits and Laplace Circuit Analysis. You probably know more about it than me.             Regards, Karl.    

Hi, I asked to solved C3 in a simple equation and then it tels me that C3 is undefined. I do not understand, because I did defined C3 with my equality where I find it's value.   Thank you 

Can the MathCAD Prime API print (or export to PDF) via the API?

Hi, I would like to have the answer to this very simple equation with only 4 decimals. Also, is there a way not to show the units ?  Thank you   Camille 

The product calendar now shows an estimated release date of September.  I've heard nothing about what's coming; as is tradition.  However, I have had tech support contact me that a very old bug I reported is fixed in 7.  (screen shifting).  I suspect pulldown menus are coming as that was something planned for 6 but didn't make it.    

to all   I think I had an example of what I am attempting but lost hard drive a while ago means I have lost it. I would like to use indexing in a Given block. Please see attached. Can this be done if so what is the correct mathcad 15 syntax? Aim is to return a vector of solution for each index i   Thanks Regards

Can someone convert this mcdx file into a Math 15 file?

to all, A bit of an open question as I do not know how to go about solving the following – if it can be done at all I have a curve C1, define between [x1,xn] and I would like to create a curve C2 using N pts so that some criteria are met. Essentially is a “double optimisation” problem. Consider the following; I want C2 to be made of p points p(xi,yi) – Generally a few points (say no more than 10) Criteria 1:-  xn > xn-1 > x1 . xn and x1 are given Criteria 2: In a given x range [xn,x+1] rms C1 ~ rms C2 . Within a given a tolerance (say +/-1%).   Is there of way of using Mathcad to find the best pair of points to meet criteria #2 Does it require some sort of loop, or is there some built-in optimisation tool one can use Attached a mcad 15 file swith some preliminary stuff - Not much

Jacobi method - show all the partial solution of the sys. iteration by iteration   Hello, I want to out put all the partial solution of the sys. iteration by iteration in a table (or m x n matrix):   itr     x1    x2    x3    x4 0      ...    ...    ....    .... 1    ....    ....    ....    .... - - - - - - - - - - - - - - - - - itr    ....    ....    ....    ....     Also i don't know why in my file does not accept itr->0   instead accept begining from itr->1.  I attached the file.    

Sorry, I have asked about it here and Alan has answered. But! I have x1, y1, z1 and x2, y2, z2. How can I plot a line in 3D between those two points (# 7 in the picture). Mathcad 15 sheet please!  

I've added the following solution to the Rosetta Code task: : Generate Lower Case ASCII Alphabet       References: 1. http://www.rosettacode.org/wiki/Generate_lower_case_ASCII_alphabet2. http://www.rosettacode.org/wiki/Generate_lower_case_ASCII_alphabet#Mathcad   Please feel free to add your own versions, additional to or replacing mine if they're an improvement.   Cheers,   Stuart   (I was going to use succ to generate the sequence of characters, but didn't in the end.  I'm just too idle to remove succ from the worksheet)

I have inserted 2 AutoCAD LT drawings into a file and every time I open it the drawing is missing?

Hello, I wonder if anybody can suggest a means to programmatically create variable names and assign values to them, using data from an Excel spreadsheet? I have attached a very simple example to illustrate what I want to do. I have electronic component identifiers (Reference Designators) in column A, and the corresponding values for those components in Column B. I would like the values in column A to become variable names in Mathcad, and the values in column B to become the values of these variables. In the example below, I have manually created the variables in Mathcad, but I would like to automate that.  Seems pretty simple, but I haven't figured out how to do it. Any suggestions would be greatly appreciated! Thank you.

I saw other solutions but they are not helpful   in my situation. Anyone have  idea how to convert  my  result? I need -0.29999999999973  show in fractional form.I checked settings, other forums but didnt find any solution. It works really strange, I have latest version of Mathcad  Prime 6.0    

I have a set of 3 differential equations which I solve with ODE. However I would like to add a constaint to c.MOAQ, which value needs to be below 0.001. How can I implement this into the ODE block?    

Dear people,   I've learned a lot from other people's faults from this forum in the past, but now I can't fix my problem on my own so I'm asking a question myself this time.   Its about the Find function, which has worked for me before, but not in this instance. Now I think it has something to do with the complexity of the equation I'm trying to solve but I'm not sure.   Maybe somebody can have a look at my file and tell me what I'm doing wrong.   Its about the A.var value which I cannot solve.   Cheers,

I am getting error as 'All evaluations resulted in either an error or a complex result.

Pivotisation of a matrix - I try to change an existing file that works with another scheme   Hello, I have a Mathcad file that do the pivotisation of a matrix but I dont like it because is too indirect and obscure.   I want to implement another scheme that is more explicit and easily understanding but does not works by now. I attached my working file that also contains the scheme that i try to implement.  

Hi there,I'am a new user on Mathcad software and i'am getting stuck on a very simple problem, which i can solve manually, but i want to practise a bit with Mathcad.My problem is the following, i got two symbolic functions called C1 and C2 in my worksheet, which i want to be equal to zero (each of them). My two variables are Ti and Tn. When i tried to solved those equation i got an undefined solution.Thanks to tell me where i'am wrong.Sébastien

Dear All  Could you help me please ? How to write this equation in Mathcad Prime ?    

I am looking to make some symbolic equations then place them inside a matrix and solve current node mesh for the answer to circuit equation. I am looking for advice on how to do this or the advice that such an endeavor is impractical. My next goal is to find a PTC defined function to extract the coeffecient for the equations for Voltage and the unknown currents (I.1 I.2 I.3 I.4 I.5). So right as now i am looking to sort the result and THEN Store the results.

Hi all,I am getting error as this value as unit:current^2 but must have units :unitless.Can anyone help me how to overcome this error.I attached my code below.Thanks in advance

I am attempting to write my first For Loop. I have a vector of values, i=0 to 10. x0 = 0.05. x1 = x0/2. x2 = x1/2, etc. I cannot seem to find any way of doing this. I have tried this, below, but it doesn't work. Please help!
