Mathcad

Is it possible to solve the ODE in attach? Thanks!

 I succeeded calculate multiply:But convert in vector "g" I cant do And quastion: Do mathcad have any method to calculate this?Like:     

I have made an attempt to extract the right set of data (column) from two different tables based upon the selection in the combo boxes, unfortunately it's not working as I want. Attached is my worksheet. Thanks for any help!   

Good evening,   I am having problems licensing my Mathcad 9! I am a student at a university in Austria, computer science branch, and got a product key from my teacher. I redeemed it at school, where everything still worked and I could use Mathcad 9 without any problems. But when I wanted to do my homework at home, my software was unlicensed. I tried to re-license it with my user + password + product key (the same one I used at school) and with the license file that was sent to me when I licensed myself at school. However, neither of these worked. When I want to activate my key at home with user, password, and license key I get this error (see picture in the attachment). When I am back at school and connected to the school wifi, I can select my license file and use Mathcad 9 normally.   Kind regards, Philip

Hello,My company is migrating from Mathcad 15 to Mathcad Prime 9.0. We have a number of Python scripting files that generate Mathcad 15 files by creating the XML data needed to generate and access Mathcad 15 files. In Mathcad Prime 9.0, it looks like the files are not purely XML data. There appears to be some sort of header and footer data, in addition to the XML data. Is there information on what the header and footer data is? Additionally, the Python scripts internal to my company just puts together a string of characters to generate the XML data. Would this work in Mathcad Prime 9.0? I need to convert the files to support Mathcad Prime 9.0, but it doesn't appear to be as straightforward as I thought.   

Hello, The Maximize function does not work properly in the following case - I need to calculate the worst case error in a current measurement circuit where x, y, z, y, v, w are the sources of error (resistors, opamp gain, offsets, temperature dependance coefficients) and a, b are the current and the temperature which I would like to be parameters so that I can plot later the worst error versus current and temperature. The Maximize function gives the correct answer - all variables saturated at their maximums only for CTOL=10^-9 - this is completely strange and unacceptable behavior! For CTOL=10^-10 the solution is erroneous and also for any other CTOL up to 10^-21: I guess these Maximize and Minimize functions are really nor working well with somewhat more complex examples which unfortunately are present in the real engineering practice! 

Hello,Why do I have 2 different values ​​when calculating the symbolic and numerical value for the same integral like below example? Symbolic calculation:   Numeric calculation:   Symbolic calculation first then numeric calculation:

HiWhen I have a collapsible area followed by a page break and I close the area,empty pages remain above the page break (see attached file with an example).I didn't have this problem with Mathcad 15. In addition with Mathcad 15 I was able to set page breaks inside a collapsible area, which is veryhandy option when the collapsible area is relatively large. To my understanding naming of areas is also missing from Prime... Any ideas how to solve these problems? Thanks.

I am installing Mathcad 14 from my installation DVD on a new PC. All went well except towards the end a window says, "The wizard is now contacting the PTC licensing server to obtain your license automatically. This may take a few moments." Then another window pops up saying, "The remote server returned an error: (403) Forbidden." What do I do now?   

Hi,i have a new laptop to work on mathcad but i can't connect to my user because i have to enter my license when i am hitting enter is says license is used how can i still connect to my user?  

Hello, why Mathcad does not find the maximum for this simple problem - it should be when x=1, y=1 and z=1 - in total f=2. For some reason x and y are kept to 0 even when the 0 is excluded from the range of search for x and y:   Thanks!  

Hello Everyone.From : (view in My Videos)To : How to animate a segment ( green ) to rotate around Z-axis ( pink ) (Mathcad 15) ? Thanks in advance for the time and help.Best Regards.Loi.

Previous message:Hello, I am trying to use the "Solve Block" in MATHCAD 8 to evaluate physical constants of materials using experimental values. I have impedance measurements and phase measurements and I obtained some equations that I am trying to place in a system.I used, I assume correctly, the Boolean "=" in the constraints field, defined some guess values and asked for the solution, like in the following text (I omit the rest because otherwise is too long). Nevertheless, there are inconsistencies probably due to the utilization of indexes (my quantities depend on the frequency, while in several examples I have seen just numbers). The red circles around variables to be calculated mean "a function or a variable name is required here". May you help me?  New message:Sorry, I used the PDF in my previous message for simplicity because the code is quite long, and my problem is general: how to use the "solve block" when the quantities in the constraints have an index? My equ

Hello, Default plot of the line passing through the point (1,1) in Mathcad Prime:     My desire:  Having a point, for example: (x, F(x)) = (1,1), I would like to be able to adjust the LENGTH of the line passing through that point (1,1), in order the length of the line to be smaller or larger as shown below. How could I do this?

I am a beginner using PTC MathCAD9.0 30 day trial version.I have a questions about how to install a function to read and write in HDF5. When I contacted PTC, I was told"In order to use custom functions in the latest version of Mathcad,you will need to rebuild DELL from the provided source using Visual Studio, etc. (Please refer to the attached zip file.)However, the custom function you are inquiring about is not a standard feature of Mathcad,so our support cannot provide a detailed response. We are unable to provide a detailed response."Please tell me how to rebuild DELL and to use the function.

I am a beginner who is currently using PTC MathCAD on a 30 day trial version.I have two questions about how to use functions for reading and writing in HDF5. ①I have read the article published in 2016(https://www.ptc.com/ja/support/article/CS189647).However I cannot use "ReadHDF", "WriteHDF" to read/write HDF5.I obtained the HDF environment by following the workflow described in the word file in the zip.(I downloaded the latest version 1.14.2, not ver 1.8.11 as described)I have finished up to 2.) in the "Install and run the Mathcad_HDF.dll" in the word file,but when I open Mathcad_HDF.mcdx file and type Mathcad_ReadHDF (or Mathcad_WriteHDF),Mathcad crashes and the operation screen disappears.Please tell me how to solve this problem. ②PTC told me that in order to use custom functions in the latest version of Mathcad,we would need to rebuild DELL using Visual Studio or other software from the provided source,but since custom functions are not a standard feature of Mathcad,

Dear SirsI have two screenshots below, one of which shows the calculations I've done for KRF and Delta I. I would like to use this data to create a chart on another screenshot. Could you please teach me how to plot it?Thank you very much. 

Hello,In the attached sheet, i have math regions and text regions together within one big region. How do i  remove this big region so i can have only the text and math regions outside this big region? Thanks!Sam 

I'm currently using my school's Mathcad license of 8.0.0.0 and currently trying to symbolically solve a system of equations but it compute. Is there any work around this for the 8.0.0.0 version?   

Good morning friends of the group, sorry if my questions are easy, but I'm new to Mathcad. I don't know how to solve this type of equation, I would like the answer to be in degrees.The answer must be 120º.
