Is it possible to set Page Size larger than 11" x 17"?  My goal is to move the dashed page lines off the screen.  If I have a plotter that prints ARCH E (36" x 48") I should be able to tell Mathcad.  thanks,russ

I am working through the math equation entry tutorial and the operation of Ctrl+Shift+I to enter a definite integral into my equation returns a popup about a problem in AMD Adrenalin software related to screen capture to change a setting but I went into the AMD software and can't figure out how to fix the problem.

I need to download the installation package

HI,  Does anyone have access to the structural engineering worksheets? I am after a Eurocode Wind load and moment frame example? These are not in the civil sheets and I can not find any to purchase on the site. Any guidance will be appreciated.  Thank you,  Casper 

Does anyone know if it is possible to create a unit for optical power loss in optical fiber communications having the units of dB/km?  Thanks in advance for any assistance.

Friends, I need a function that returns a vector containing n natural random non-repeating numbers (Lotto game)

Hi everyone, As a chemical engineering student, I am trying to solve a pipeloop problem.  I stated all the necessary balances (see below):And the other necessary formulas:which I want to solve for Fh(v),Fo(v) and Fc(v) from v=0 until v=VL. now I've set up this solve block:  which in theory seems solvable, as there are 5 unknowns and 5 equations. Is this the correct way to solve this problem? With kind regards, Tim                    

I'm looking to see if my company has an available license for mathcad and if not possibly acquire one. Our PTC account gives me access denied when trying to manage licenses and I'm unable to upgrade the account as I don't have the information necessary.

Hi, Mathcad v3.1, v4.0, v6.0, v8.0, v15.0 run with OpenJDKAre these versions able to run with OpenJDK instead of Oracle Java?   I am hoping that one is able to install the OpenJDK and then install the MathCad.  Please let me know if this has been tested and works.I am not able to find any information on this site.Thank you.

MathCad 14 factored the function sinx(x). It is known from other investigations that this function has only real zeros. If you now look for the zeros of each factor (the terms are in parentheses), then MathCad calculates complex zeros that cannot be simplified. Where is the saw stuck here 😉 .Kind regards, Alfred Flasshaar

Hello all, I am having some issues with Global Definitions.  I am trying to define the following: kJ = 1000JWhen I do this, Mathcad (7.0) accepts the input, but the "kJ" stays black.  It doesn't turn blue like other definitions I have used in the past.  I am using a wrapper for REFPROP, and the author has the same definition in his worksheet.  If I copy that into my worksheet, it works fine.  But creating my own definition from scratch doesn't seem to function properly.  Thus, when I make function calls for fluid properties in kJ/kg, i.e. enthalpy, the units are not correct.  See the screenshot below. What's the difference between these two?  How do I make my global definition like the one above?

There is one more calculation to be performed based on the interperolated values.  However the value of appears to change after the calculation of .  I do not understand why?  Any suggestions.   Thanks.    

I'm just trying to make a vector from a function so that I can export the valuesHowever MathCad Prim 8.0 give the error "This value must be a scalar or a matrix". Why???Needless to say, not having the ability to just select all values from an array and copying and pasting, like it was possible in MathCad 15 is really, really annoying

The development of a famous polynomial p(x) of degree 45 has already been discussed here. Now I searched further and found Vieta's approach to the ingenious determination of the zeros. His approach, identical to p(x), is p(x) = 2*sin(45*arcsin(x/2)). Mathcad 14 fully develops this. But I fail to get the usual polynomial structure to be able to compare it with the classical default. What am I doing wrong in attached file? Kind regards at Christmas time, Alfred Flasshaar

It wont install. The installation package will download, I give permissions to make changes to my computer, the extraction happens, a spiral comes up on my cursor, then nothing happens. I have windows 11, other windows 11 users I know are having the issue but those on Windows 10 are not having problems. Has anybody else experience this or have a solution?

Hello,As shown in image I am trying to calculate temperature change. I think units are compatible but mathcad does not allow calculation. What is my mistake, I could not find. Could you help?  

I have a german installation of Prime 7. As I work for an international company, we use english in our documents. When I input text, the spell check always switches to german. So I have to manually format every text to english. How can I force MathCad to spell check in english as  default?

I implemented a solve block, which worked with Prime6. Now with Prime7 it does not find a solution anymore. I reworked the problem using a simpler function to make it easier to understand and even this easy equation is not solved. Unluckily I have a new computer for some weeks, with a completely new installation and only have Prime7 installed.Both versions of the solve block do not work. I know, that the equation could be solved easier, I just used the solve block for demonstration (see attached SolveBlock). In my application the function is much more complex and it worked with Prime6 (SolveBlock_original).

I am trying to set up a worksheet something like this (full size image attached)I have a number of issues which I don't think can be solved, and which mean that Mathcad is not the right tool for this particular project.  However, I am posting this to see if anybody can persuade me otherwise.Firstly, the two combo boxes (each with the same 200+ rows) cannot be populated through code, only by pasting values or entering values manually, one by one.  The source data for the combo boxes comes from two columns of an Excel workbook.  For the time being I am only working with the first combo box.  I have had help with this aspect but in my opinion Mathcad should have a way of populating a combo box via code.The idea is that when a different acid is selected from the combo box, the plot and/or chart component are automatically updated.  This is working as far as the plots are concerned (i.e. both the native plot and the chart component automatically reflect the changed

I would like to create a series of nested If statements to calculate kp_figure for Multiple values of Θ (120, 110. 100, 90, 80, 70, 60, and 50), with a secondary If statement for each value of Θ as shown in the calculation for Θ =120.   Any assistance would be appreciated.

Please call me as the product installer for math as 8 will not work.Thank you,Roland Diaz

I need to install full version PTC mathcad. The mathcad license was transferred on 12-07-2022

Edit: Possibly solved? That was quick... See bottom. How can I use a relative path when including reference worksheets? The documentation suggests it is possible: "By default the include region displays the absolute path to the referenced worksheet. You can edit the path and make it relative." I am collaborating with colleagues on a number of worksheets that include references to other worksheets. These are documents that 3 of us access and edit. We are currently using OneDrive, but the issue would remain even if all documents were emailed around. The "Include: path" changes, but all worksheets can exist in a single parent folder, or even a grandparent folder (which should work with a proper 'relative setup') I have tried various ways like: ../  or ./ or / or //https://learn.microsoft.com/en-us/dotnet/standard/io/file-path-formats I have found some ancient* threads discussing and confirming this ability as far back as 2004, but nothing new, or recent

This month’s challenge is around field goals in American football. Create a Mathcad worksheet where you calculate the following angles from a given line of scrimmage for making a field goal: The horizontal angle between the left and right field goal posts (18.5 feet apart). The vertical angle between the horizontal bar of the goal post and the upper height of the goal post arms. How can you show how those angles change as a function of the line of scrimmage?   Factors to take into consideration: Assume the football is kicked from one of the hash marks (offset from the center of the field) and 7 yards behind the line of scrimmage. The goal post is located at the back of the end zone. The horizontal bar is 10 feet above the ground and extend another 35 feet. For this exercise, the football must pass through the box defined by the goal post. American football uses yards, feet, and even inches, so you might want to take advantage of units in Mathcad. Bonus: Can your worksheet hand
