Mathcad

Could not find this in a search, which surprises me.  Is the following not possible in Mathcad 15? Thanks for any help.  I can make it work if I use mathematical tests, But, I like to learn new things.Reg  

I guess something is not working with units for my plot can someone have a look and tell me what's wrong  

Hi,Why aim getting this error?What should I do to get the answer in units mW/cm^3 or watts/meter^3 JacobPrime 8.0     

Hello,     Why? Because results for a, b, and c should give:   MC Prime 9 fille attached.

Hello, How do I calculate the smallest difference between any two rows in a row in the matrix?Thanks,Sam

HII need help for write check, simple attachment in the Mathcad.    

Hi Everyone, I have Mathcad Prime 9 Floating License but I cant activate the license, So anyone  can help me? *NB : I dont understand Flexnet license server  

Hi experts. I would like to know.If I could use command method to enable the calculation area or disable it.For example,I have two condition, in one condition I want iLr = 5A, in the other condition, iLr = 4A.I know I can use "if" command to do that. but sometimes I prefer to disable/enable area.   

Hello Everyone.From : Mathcad 15 , How to : M , Symbolic Evaluate ---> ?Thanks in advance for your time and help.Best Regards.Loi.

Good afternoon friends of the forum, I have a question about units,as it is showing an error and I don't know how to solve it.    

Hello, we're trying to solve integral equations, and there's error on getting the final integral value in Mathcad. anyone can direct how to get the following integration done in Mathcad?There's a following error: More than one independent variable for keyword solve. 

Is there a way to remove the MathCad  Express watermark from a printed MathCad document?   

Is it possible to solve the regression analysis problem in attach (Mathcad 15 & Prime 6) by changing guess values? Or the formula does not approach such set of date?

The examples using Solve Blocks show a plain box with Guess Values, Constraints, and the appropriate Solver inside, but the box is otherwise "undecorated". When I lay down a Solve Block, it has labels on the side for "Guess Values", "Constraints", and "Solver". If I remove unneeded space inside the Block, the labels on the side "ride up" so they overlay each other and look just plain ugly.How do you suppress these labels so that the Solve Block looks like the blocks in the Help Files, i.e. just a box with no labels? I looked and couldn't find it in the Ribbon (I may just have missed it), and right-clicking or left-clicking the Block didn't seem to work (unless I failed to find the Magic Spot).

As per the original Post.    I believe I have the premium version of Mathcad PTC Prime 9 - but "ctrl" + "enter" never worked for me either.    Actually, as far as I know, I have Professional version of Mathcad PTC Prime.  M > About > just says I have Verison Prime 9.0.0.0.  I pay something like $600 a year for the license.    Anyway "ctrl" + "enter" doesn't work for me for whatever reason.

I successfully converted a number of .mcd and .xmcd files to .mcdx files in the last 2 days. (using Mathcad Prime 9.0 in the Mathcad Express version, but with 26 days left in the free trial period ) My computer updated and restarted last night (Windows 11). Today, the .mcd files I have attempted to convert have failed. The xml log file for 1 conversion said "Could not start Mathcad conversion process. Check that .Net Framework 3.5 Windows Feature is enabled". I enabled that feature in Windows (following the Microsoft instructions), and restarted the computer, but subsequent conversions also failed. The same message is in the .xml log file of the conversions attempted after enabling the NET Framework. I have attached the xml log file and the log.txt file that were produced in the conversion process. Thank you for any help that can be provided.  

I know there is a wrap feature like:   But is there a feature to get the answer at the bottom of the equation - like: Thank you.  

I may be asking too much, but I have a general question about using the root function in a series of variables and constants.  For example, how can I program the following in MATHCAD 15 to find the roots xi of the function Fi wherei=1…5Fi = (1+Ki*xi)*(xi*cot(xi)-1) + BKi = known constants for all iB is known constant  Thanks for any help.Reg

to all Doing a sanity check on the CFFT for another spectrum analyser in a 1/3 party toolIf one has a sine wave Asin(w*t) then a spectrum analysis will return an amplitude a=A/2 at w (or f= 2piw) . Am I correct?Therefore if one only has the spectrum as an output (and not the original time signal) then one can read the frequency (w or f ) and conclude that the sine wave at the freq (in the time signal )has a peak value 2a! Thanks in advanceJohn

I'm trying to get a programmed text output from testing if a point is inside a circle.  All of the points are either secondary ohms or degrees.  The chuck of programming seems to fail if there are units attached to the numbers.  See Below.   

Hi everybody,I have calculation sheets that utilize a reference to a different sheet that contains subroutines to calculate coefficients, factors etc. for the main sheet.In Mathcad 15 this works just fine, in Mathcad Prime 9 however, an error message (see attached image) is returned by Prime, claiming that there are errors in the calculation sheet.Has anybody figured out how to find these errors? When I open the Prime sheet no indication is given that points to the error. As I said, the sheet works in Mathcad 15, so I assume that the calculation is ok.Any ideas?Raiko   

I had a circle function that was working fine until I re-defined some of the variables as Ohms-secondary.  The plot is blowing up now and I'm not sure why.  See attached.  

I am having trouble with the onefn function in Mathcad 15. I get double entries in the 1/f noise vector and if I take the CFFT(ofn) I get a zero as the first result. Also I do not understand the mirrored magnitude plot of the 1/f Noise. I also don’t understand why the range variable even starts at zero. That would give infinity for 1/f.

Hello, @ttokoro  How to plot arrow lines like below in 2D and 3D:      

Hello everyone,I have something to ask, and maybe it's quite easy to ask. But I couldn't find any source about it. I created a chart from curve fitting, and I want to see the chart values in a table. If it's necessary, I can add the file. 🙂
