Hello,How to fill the below area enclosed between y1(x), y2(x), y3(x), and y4(x), like below with purple?          

Hi Mathcad Community, I’m working on a problem involving a box cross-section. I need to plot the shear flow distribution q(y) along the height (y). The plot should be linear in the flanges and parabolic in the webs, but my current plot is a step function and doesn’t match the expected values. Can someone help me redefine q(y), and provide the correct Mathcad function to plot a continuous shear flow distribution?Thanks for your help! 

I want to present results in a table I created.But having the variable name showing when I want to display the results is really not convenient.Anyway around that other than hiding the name with a white box? I mean...It's Mathcad...  Not Paint... Thanks

Good Afternoon Community, Need some help with solve block with Find function. Please see attached. Thanks, Boyer  

So, recently Mathcad wouldn;t open, I deleted it, then installed again but this time changed the file location. Now, I can't open any worksheet, if I don't go in the app, Open, and then select the worksheeet. Also, the worksheet in the activity bar or its location doesn't show the Mathcad icon. What can I do to fix this problem?

hello everyone, let's see if you can help me. It turns out that I want to plot a root locus.It turns out that I have to solve the equation [1+ K G(s)* H(s)= 0] for each K.For a given K I can do it with solve: for example:G(s):=10/(s^2+2*s+10) and H(s):=5/(s+5) for a k:=3 gives me the following result.R:[-7.75;0.375-5.07i;0.375+5.07i]how do I get the same within a program by varying k by different values? 

I recently learned about the following problem, whose solution function u(t) requires determining:u´(t) = -u(t)/t + 1/(t^3+t), u(0) = 0I intentionally called this problem a riddle 😉 .Please answer in MC14-readable format.

Hi,I have an equation likeWhere Q(x) is some complicated complex function of x. This way f (or sol, if you prefer) is a function of x.I would like to make x a range so that I can plot f as a function of this range.Is it possible to do that?Thanks  

I have an array (numbers of rows - 1,  number of columns - can be different). Example: I enter a variable in mathcad d = [1 5 10 15] and i want this array to be displayed in my list as d = 1   d= 5 etc... Help please. Preferably in JS. Translated using Google Translate.

Mathcad Prime 7 I'm trying to find solution with solve block, but possibility to find result depends on "x" (would like to find) initial value. How to determine proper "x" initial value? I would like to use Mathcad for automation, but if it's not clear what initial value I must use, it will not be possible. Thank you!

HI team, please anyone help me to get 3D plot. I have attached a mathcad sheet. Thank you

I am developing a sheet to calculate section properties of steel sections using Mathcad Prime 10, however I find the integration gives zero value for web thickness less than a number for my specific example.  see below screenshot and attached file. The Ay gives correct area, however the Ax doesn't. I have tried different values for tw which gives a correct result when it is larger than a certain number. For example in the I section if changed to 30mm, the integral gives correct answer.  Appreciate any help please. 

I have a Prime calculation that takes days to run--it's a complicated integration.  If I halt the calculation using the "Stop All Calculations" function on the Calculation tab, save the sheet, then return to that sheet later and re-activate "Auto Calculation" I believe the calculation will continue from where it was halted, even if the file was closed and reopened.  My question is whether or not this halt/save/continue does in fact continue the calculation rather than restarting it.  If I select the "Calculate" option the sheet will definitely start over from the beginning, but that's not what I'm asking about.  I can't submit the sheet due to corporate limitations but the question is general enough someone should have worked it out by now.

Hello. I have a table that generates two sets of info.One is the actual design forces, and another is a minimum.I want the maximum from each case.For the 8" wall I want it to give me 10 psf and for the 12" wall I'd like it to give me 15 psf.I have googled but no luck.  I can create a max function but it gives me the maximum of all four numbers. There a way to do this? 

HP computer and printer are working properly with other applications.When I try to print a Prime 10 workshheet with colored plot traces, all are Black.Used HP Smartfriend service and we found the problem only happens with the installed Prime 10.Seems that I have done something stupid recently: I am 89.When I try to print, my HP Elite 7200 printer does does not show a color option.Could there be Adobe problems? Do I need to re-install Prime 10?

Hello everyone, I am solving mass and energy balances for a CSTR using odesolve in a solve block in Mathcad Prime 10. The system includes species balances and an energy balance with the heat of the reaction. However, the solver is not working.Are there specific issues with my guess values, constraints, or equation setup that I should check? Any guidance on properly structuring odesolve would be helpful.Thanks!

Sorry, I don't know how to get the Vadl value? Could anyone help me please?

Hello, New user to Prime 9, moving from V15. V15 had an option for regions to "push regions down as you type", does prime 9 have an equivalent?   

I'm attempting to moved my networked mathcad license to a new server. I've followed the support article  (https://www.ptc.com/en/support/article/CS20911?oskarSession=4ed21d13-73b5-4882-8e39-d12bebb4a6bc&source=support_assistant) and to how to install the service manually (https://www.ptc.com/en/support/article/CS62129?oskarSession=4ed21d13-73b5-4882-8e39-d12bebb4a6bc&source=support_assistant) and everything looks fine but when I go to start the license it won't start and when I attempt to re-read the license it fails. the Debug log isn't showing anything either.

hi @LucMeekes  I am passing array of equations into an ArrayAnd then want to get this function in the form of matrix like below wherein A is the Matrix, which I want to pass to reference calculation worksheet, which is called within main worksheet.It gives the error to check label.Can anyone help me to understand and solve this.I could do this in Mathcad 15 and now struggling in Prime. Regards,JK_9391805  

I have two simple definite integrals and I want to find the angle (common to both integrals) where their results will be equal.  I've done it by guessing, and now want to solve it automatically - but I'm having trouble with Find.   

Im a heavy long-term user of mathcad. I regularly embed math regions within text regions in my calcs. Today, I now find whenever I try and copy a math region within a text region mathcad constantly crashes. It never did this before.  A few years ago there was an error PTC was aware that MS caused with an update where you could not copy and paste math regions form a text region into another text region. I wonder if there has been a recent update that has broken mathcad.  I find i can replicate the constant crashing when in a text region contain embedded math regions, if I refer to a math variable using a text and subscript within the text region, It will crash constantly when copying a math region in that text region above the text subscript. If I use my traditional approach pre-Prime 10 of using a math region to refer to the variable with subscript no issues. ( I typically see MathCAD crash once or twice a year, today its crashed thirty times.) See at

I am trying to achieve something like the below (the equal sign is text only). I'm not even sure if this is mathematically possible however, and may require some manipulation to achieve?Here is what it looks like when I try to do itAppreciate any possible help with this, it's been a long while since I studied matrices!I am on Prime 9.0 if that makes any difference.
