Green shows circle of half.
So, I've been able to work through all the values so far but seems like I have a problem with the summation notation since the THD of alpha does not converge to a solution:
hi ptc team,i use PTC Mathcad Prime 9.0.0.0 convert xmcd file to mcdx, but there are so many errors in mcdx file,how to resolve? please help.
I encountered an interesting and maybe concerning problem in how MathCad solves its intergrals between different versions. In the version of MathCad I use (MathCad Prime 9.0.0.0.) the integral I wanted to solve and get an analytical expression to gave one answer. This answer is different from the answer you get on older MathCad versions. I noticed this from some old reports where this integral was solved via MathCad about 20 years ago and they get a different analytical expression. This expression you get from the older versions is also the same you get by solving the integral completely analytically (which you can do via variable substitution). The difference between the answers seem to be very little and the residual could just be some numerical truncation maybe, but as we can see the difference is not completely negligible depending on what you are after. Has anyone encountered something similar to this and know why this is the case?
Is it possible to export out a scalable vector file from Mathcad prime worksheet? If yes how can I do that?
Hello all, I'm trying to do a fit for the transient thermal impedance of a transistor based on a set of points that I extracted from a datasheet. At first, I tried to do a simple polyfit, but it seems that the fit can diverge to very high numbers or even go negative, which may not be acceptable in this case, since the thermal impedance is strictly positive.I tried to do a fit similar to the Foster thermal model, based on R and C couples of values, that is usually used in the thermal models of electronic components. For that, I tried to use the LeastSquaresFit function, but it doesn't converge in my case, script attached below. Could anyone explain the reason for the divergence ? Is it the input data or the way it is used ?In the case I try to separate R and C values to 2 vectors, should the guess vector be the stack of the R and C vectors ? The documentation of the function doesn't explain it in a clear way.Alternatively, in the case of a logarithmic regression, is it po
Hi, I need instaling Mathcad 10 in another computer, please send me download link.Thanks
How do I get Mathcad to get from this:to this:without having to redefine f(x) myself?
Hi,Which software do you recommend for verifying bending moments and shear forces in a beam from Mathcad calculation?I use the beam calculator https://solveredu.com/en/beam-calculator/. It's generally good, but do you have any other recommendations?
Hi All, What is the formula to stack the zcal into a vector and rearrange the vector up to the zcal value. Can anyone please advice?
Dear All, Found the solution to stack and filter the vector to calculated value. I am looking for a loop or formula which I can calculate area under each section of the vector and then cummulate them.
Hello, I have been having problems with saving/printing the file to pdf. Some pages come out blank (only header and footer is visible but not the content of the page) in pdf without specific reason. It does not happen in every worksheet, just some.Let me know what I can do with it.
Hi, What is the symbolic engine used by Mathcad Prime (all versions greater or equal than 7)? What is the numeric engine used by Mathcad Prime (all versions greater or equal than 7)?
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 ?
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 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...)
