I announce a competition - who will create the most interesting and beautiful portrait of the roots of two equations. I will send a hard copy of my book (2⁵ Problems for STEM Education - 1st Edition - Valery Ochkov - Rout (routledge.com)) to the winner of the contest. The end date of the competition is April 1, 2022. I will personally determine the winner. Materials explaining the essence of the task, in attachment. In the picture - a sample of a work of science and art, which should be submitted to the competition.

Even though the function is defined when doing ans := ShahST(G), MATHCAD says its undefined. Please advise. Thank you in advance.  

Hi I have 2 equations that are written symbolically. and there are 2 variables : "D" & "z"  I cannot solve the equations even in solveblock . please help me . my file is attachedThankyou

Hi! I'm a college student having problems with the creation of the matrix. The informational failure is "Found a similarity while evaluating this expression. You may be dividing by 0 or inverting a similar matrix." Please help! 

Hi Guys,Can anybody to simplify this program?I must run for “k” and “i” twenty times the block.CarlosRomero

One legacy feature that has still not been integrated into Mathcad Prime, is the ability to provide companion XML files that integrate Custom Functions documentation into the Mathcad interface.  Legacy Mathcad would read these XML files and add the new functions to the list of internal functions in the Insert Functions panel under their own, specified Function Category.Legacy Insert Function Panel While Mathcad Prime does contain a Functions panel for inserting built-in functions (can be triggered with <F2>), it does not allow for incorporation of categorized Custom Functions into that interface. For DLLs containing a large number of Custom Functions, this can be problematic for users to know which functions to use, what they do, what parameters are needed, and the proper function syntax. I've managed to create an open-source add-in, CustFunc, that brings back the Legacy insert functions behavior for Custom functions, reading the function names, categories, syntax,

hello everyone!I want to set this equation equal to zero and find the unknowns c and k. Of course, I have to use the gamma function for this. Does anyone know this subject?

I want to optimize solution based on conditional operators in Mathcad Prime 8. Please help 

Hello, I am inputting a vector into a for loop, but struggling to get a vector back for the output.  I would appreciate any help.  I could not figure it out from other examples on this forum.  I am wondering if I am making an error in the initial step of the for loop?  Thank you.

Here https://community.ptc.com/t5/Mathcad/One-electrical-task/m-p/926303 was all OK!

Using: MathCAD Prime 9.0Hello,I am trying to add a scalar value to every other column in a large matrix (each element in an even column). I included a screenshot below of a small scale example of the input matrix M, scalar value to add, and the desired output. I thought this might be able to be accomplished using a for loop of some kind looping through the elements and only adding the scalar to the even columns, but I wasn't able to figure out how to do this.The real application is I have a large matrix of time and current values with every other column being the time columns, and want to add a scalar value to shift the time values. Any help would be greatly appreciated!

I got a notice that Prime 10 is coming, or here, but no date. Does anyone know when Prime 10 will be available?

Having an issue with the solve block, most likely because of my little experience with Mathcad. I do have a function in the constraints, but don't know how to solve the issue. Any recommendations will be greatly appreciated. 

Hi, *** I attached a Mathcad sheet exemplifying the issue*** I have a variable j defined below:This variable can take values like [1], [2], etc. except when type is 12, in which case j=[0,1,2,...,11]My idea is that the user can select an individual type or select type=12, which includes all types from 0 to 11..When I multiply two vectors using j to access their elements, it works as intended:       The problem occurs when I want to store this result in a variable.  I want to get rid of those zeros and mimic the C_j * M1_j results shown above. I tried to create a another variable i but for some reason it gives an error: I wonder if there is a cleaner/easier way of doing this? Regards,    

See please Prime 6 in attach. How to solve this task not with SI but with CGS (not with F but with cm)? Very interesting article about this problem Dmitry Sivukhin "About SI" 1974 

Version : PTC MathCAD Prime 9.0.0.0So, I had a problem statement in one of my bridges where I had depth as varying (basically z coordinate value with a certain formula that could be followed).So, here I used a constant formula which could be used for all points of vertex needed in z cordinate which I defined as various variables that it picked automatically. And worked & I could get my function sorted. where I stored my variable values reading from excel which then used this formula for all z coordinates and formed as we move along x axis.So this basically is the solved oneNow, my new problem statement in which I am using my same sheets, is that I have different varying values both in y and z coordinate which will be reading from my excel sheet. But the formula is not same for each point of vertex or cross section i.e., y and z coordinate points (different formula).The y & z values have to use the formula's as below for each y & z coordinateNow, I have stored these variable

My company currently utilizes the Mathcad Prime conversion tool to convert Mathcad 15 files to Prime. We auto-generate .xmcd Mathcad 15 files by creating them as .XML text, and then convert them to Prime to open them in Mathcad Prime 9 since Mathcad 15 is no longer supported. Is there any plan to get rid of the Mathcad conversion tool in the future?? We really need to know if the conversion tool will eventually go away, as we would need to determine another way to auto-generate the Mathcad Prime files without going through the Mathcad 15 .XML files, then converting them to Prime.

As per the original post.    could you convert this one to .sm? if it's not possible, at least for the .xmcd format.   thank you!!

I am an adjunct professor and I'm using PTC Mathcad Prime 8.0.0.0 [Academic] I get a message when I start the program ""License expiring (full functionality - X days remaining).  I can't locate instructions on how to renew my license. The chatbot is useless. Can someone helpme? Tom Jenkins

In Mathcad 15, if you have equations scatter along the sheet you can highlight, go to format, and the select align regions from the drop menu. How do you do that in Mathcad prime 8 ?       

Please include detailed documentation such as screenshots, images or video.Hi we are the old user of Mathcad, Due to some issues we had gap more than 5years, now we are back and recalling the usages.We hope it is posible to create involute profile in MATHCAD software. We tried something but could not recollect the same.This profile creation would be useful for who are designing the Gear so that they can understand the impact of correction/undercut etc.Anyone tried the same in Mathcad software is so pl.suggest the approach/methodology or is it good to prefer the some other modelling software? I request mathcad experts suggestion in this. Regards  

I have defined the more than one values for a variable.The answer 0.21 mm is wrong (0.1mm is correct value).Kindly figure out why the answer is wrong. Regards,GSVP

Hello, Currently I have been facing some errors to solve differential equations using AdamsBDF solver.Your kind help or advice will be very much appreciated.Please see the belwo images and attached file for equations and the problem with "D"_Red Circle.   Thank you.  

I am doing some image processing in Mathcad Prime 9.0 and the path to the image files is so long that it runs off the right side of the screen. I see a discussion from 2011 for setting a path in older versions of Mathcad (15?) but I cannot seem to find that option in Prime 9.0. Well, as you may see from my other message, I switched to MC 15, but has the same path issue until I learned that I could use character strings as variables.   So, now have two path variables and a third string name set to the file name, and I concatenate all three with "concat" in the following manner: Array := READBMP(concat(Path1,Path2,Image_78_7))
