Mathcad

Could not install because it would not accept my password or redo a new password to get a PTC.COM account.   Would not install MATHCAD PRIME 30-DAY TRAIL.   too many hoops and hurdles....

an unhandled exception occurred on the dispatcher thread comes and I cant write any math functions

I am trying to get the values using solve block but it is giving me error which does not resemble anything. Could someone please help me here 

As per the original post.    I am encountering the vectorization error that is common when converting old mathcad files to Mathcad Prime 10.  Has anyone updated this sheet for use in Mathcad Prime 10?

using Prime 10 and 8 and getting the same result.  when using the floor command and getting the incorrect output.  did some checking and found Mathcad is rounding out to 21 decimals places. is this something where we should add a step to round a previous set of calculations before adding the Floor command? or am I doing this incorrectly?  See attached file.  

I am getting incorrect units I wanted to get unit H for Bm but unable to get that can someone help me here 

Hi Mathcad Team, Last week I got a message from our Custommers, he has old version of mathcad which mean Mathcad 15, and he has a license issue. We tried to solve the issue, but we got stucked. The new license mathcad Prime can't be installed on their mathcad installer setup So,here is my question, is mathcad 15 is not available anymore in 2025? do you have any information about it anyway he has a locked license

My computer was attacked and all my files coded with aamv ransomware virus.My Mathcad Prime 6 (MP6) was in part damaged.I can write comments between the mathamatical  formulas, but, if I come back later and I want correct the written text my MP6 chrases down immediately. I must write text in Word, copy here and paste in MP6 worksheet. How can I repair this problem?Under windows I have only Modify and Uninstall possibility. My Windows 11 Pro was heavier damaged!Pls support me asap.

I am trying to get the answers using the minerr in solveblock but somehow minerr seems to be doing nothing. Can somebody provide any insights on this what I am doing wrong ? 

Good afternoon!After few days of fighting, i came to conclusion that it is better to write hereBasically, I have been trying to open Mathcad 10.0.1.0 , but it doesn't open at all after crashing few days ago (tried to reinstall it as well), hope somebody could give some hints or help

Hello Mathcad community, I ran into an error while using the root() function on a linfit() polynomial in Prime 10.0.1.0.I approximated a function by using the linfit() function on two vectors for the x- and y-coordinates respectively. The resulting coefficient vector for a cubic polynomial approximation is shown below.The approximating function can now be written as below (as a dot-product):  I need to find the z-coordinate for a given value of s(z), so I want to use the root() function to do this. When entering the function as specified above, the root() function gives me the error "these matrices must have compatible units".  However, when I use the individual polynomial coefficients from c_cub to specify the s(z) function directly by expanding the dot-product, everything works fine.  Any idea why this behaves differently? What am I missing? Thanks for any insights on this.Joost   

Hi I need a function which makes it possible select a image/picture based on a function.example:if case=1Display image 1else if case=2display image 2end

Hello, Sorry I know this issue has been raised before and I have searched but the proposed solution to that specific problem was beyond my knowledge of mathematical languages.  I have defined a range (via step range) to give me a list of values to input into an equation to allow me to graph the result. This worked fine in previous versions but since upgrading to 10 it has become broken. I understand that its something to do with how Mathcad Prime defines vectors now or something but I can't seem to get this to now work. Any pointers would be greatly appreciated. I have attached a few screenshots of the problemSince the update I get these errorsBefore the update...working fine and allowing me to plot on a graph

Hi there, I was wondering if mathcad can draw this sketch ? in Prime 10thanks in advance

I am using Mathcad Release 15.0 and DatecodeN/AAutomatic scaled values on plot are different from the computed ones (when listed as a vector).Here are the errors that I facedNone

I recently received the following task from a competition:Calculate lim(n-->oo) [n*integral(from 0; to 1) (x^n/(x^n+x+2024)].Using derive, MC15 and Maple I got three different solutions. Can Mathcad solve this task?(Solution: 0.0004937...)

Mathcad Prime 9.0.0.0 works fantastic on my laptop screen. When I drag the window over to my 2nd monitor it will no longer allow me to move the text or equations around and it shows a not allowed symbol. Does anyone have a solution for this issue where I can use the software on the other monitor?

Join Team Mathcad plus guest presenter Marius Pop from AAC Clyde Space in Mathcad for Electrical Engineers! Originally aired February 12 2025, but available now on-demand.   This is the long-awaited EE flavour of our "Mathcad for ___ Engineers" series (we previously had Civil and Mechanical). Like the others, Anji gives a brief introduction on what Mathcad is and why electrical engineers use it, and then Marius showed examples with two Mathcad worksheets on classic problems that engineers may use Mathcad for; he solves these in several interesting methods. The remaining time was be used for live Q&A, moderated by yours truly.   The replay is available now at this link, as well as all presentation materials.

Mathcad prime 9.0This is quite a lot to look at, but I'm struggling with getting this graph as well as the following two to accept my values. I'm relatively new to Mathcad, so any tips would be more than appreciated.ive tried expanding my values to use less variables, but nothings seems to help this issue. 

Happy New Year! This month's challenge is based around electrical engineering, specifically an AC circuit.   Calculation Challenge An AC electrical circuit consists of the following components connected in series:• A 120 Volt 60 Hertz power source• A 50 Ohm resistor• A 0.20 Henry inductor• A 10 micro Farad capacitor   Calculate the following for this circuit:• The reactances of the inductor and capacitor• The impedance in the circuit• The current in the circuit• The power dissipated in the circuit• The phase angle of the circuit   Graphing Challenge Using an XY Plot or a Chart Component, graph the following in the same plot or chart over a minimum of 2 cycles:• The current in the circuit.• The voltage in the circuit.• The voltage drop across the resistor.• The voltage drop across the inductor.• The voltage drop across the capacitor.   You can use the values from the calculation challenge, or you can use generic values. The point is to communicate that the current, t

I am having trouble figuring out how to use LOOKUP with matrices. I am using Prime 10.0. "a" is an i x j matrix generated from numerous previous calculations."b" is also an i x j matrix, with each value being a constant in the attached file, but will also be non-constant in future calculations."c" is a 2 column matrix that is generated by reading a 2 column Excel table. What I am trying to generate an i x j "d" matrix that is calculated as follows:- if value in "a" is less than the value in "b" (same position in each matrix), then lookup the "a' value in the first column of "c" and return the value in the associated 2nd column in "c", or- if value in "a" is greater or equal to  the value in "b" return zero. If tried a couple of different methods, but either get an error with the vlookup function (see attached), or i get all the values in the i x j "c" matrix equal to the calculated results of the "a" matrix 0,0 position (although calculated correctly for the 0,0 pos

Hi guys, can anyone help explain why this doesn't work? I tried whatever I could to find out what is the problem with no success. Thanks. 

HiI tried to transfer my mathcad license to my new laptop.I requested at support, and they sent me that email with the file that i had to save on the new laptop in order to transfer it. But when I'm attaching the file in mathcad it still says that the host id is invalid.How can i fix this?

Dear experts,I have a dataset, and I need to calculate the areas of four regions within this dataset, as shown in the image.I would like to use Mathcad's integration function to perform this calculation. How can I apply the integration function to the imported dataset in Mathcad?
