Hello, I am working on an assignment that asks me to "plot the function (y(x)) and the first derivative of the function." Now my function is (2x^3-x^2+3) and its first derivative (6x^2-2x). For some reason, I cannot get the plot to show up like I know it should, It just doesn't look right. How would you all go about plotting this? (PTC Mathcad Prime)

Hello,I am quite a beginner, but I cant find useful hints in the internet for my problem.I wanted to fill a Matrix with values of other Matrices, but the result is strange for me, almost only Zeros? I guess i made something wrong with the local assigning?i attached the file, and made a screenshot 

HiI'm trying to remake an old template for solving a differential equation on a free falling hatch in Mathcad Prime 9. Attached is the old version of the file from Mathcad 15. When I try to set up the rkfixed command after giving all the same info, I get an error code that the function D, doesn't converge. I've tried a few different ways of doing the substitution in D, but I've never gotten the solver to actually solve anything. It either says that D doesn't converge, that t is undefined, or unexpected error, this is a red underline on D. Is there a way to make this work? Any help is much appreciated!

Hello,I'm having a problem finding the solution for a set of equations. Using MathCad Prime 10The usual method for solving this exercise is to due a iterative process assuming values for L4 and verifying for which value one of the equations is the closest to 0.I can do it manually inside of mathcad but have not made the solve block do it for me.Is this because the solution is approximate?I am attaching the mathcad file. 

Dears, The error appears when I changed the boundary from 10^3 to 10^5 in Odesolve block. May you help to fix this issue please.I am using Prime 9.0 Thanks in advance BR

I have a list of data. Some do not give a solution within the tolerance. What is the best way to ignore and move onto the next set of data? Is there a way to set a more coarse tolerance value? Prime 10 attached.  

I have created a dll file with some functions, but could not use them in Mathcad. I want to use the function ComputeProductAndQuotient() in mathcad.Could some one help us? 

Hello everyone! I have a graphics problem and that is: after having determined the equipotential lines (see photo) in a system with a square section and infinite length, made up of metal plates isolated from each other and at different potentials, I do not know how to make the field lines orthogonal to those of the potential. I have fixed two constant values ​​for the increments dx and dy. I attach the worksheet:  

EDIT: IMMEDIATELY AFTER POSTING, I SEE THAT THIS MAY BE A PRIME 10 BUG - CAN SOMEONE PLEASE CONFIRM? I am attempting to solve for a single variable (vf) by creating an equation that has the root function on the RHS of the equation. Rather than try to explain with words, here's a picture of the problematic function. Problematic Function I am passing multiple variables to the function that are defined above: Testhp is a variable defined with units of power, Fan is a matrix formed from a READEXCEL function, and the values are unitless until later extracted by column and appended with appropriate unit values within the worksheet, D is a variable defined in units of length, fluid is a string passed to a Mathcad wrapper that is used in an included worksheet, t is a variable defined in units of temperature and p is a variable defined in units of force per length squared. I find it odd that there is no error reported by the equation above the equation reporting an error, bu

Any Mathcad 6.0+ fans out there?I've been using it since 1995. I got the Mathcad 7 and 8 upgrades and hated them. So, I've been using 6.0+ ever since. Mathcad 6.0+ ran fine on Win 95, Win NT, Win 98, Win 2000, and Win XP. Win 2000 and XP were a little trickier to install. I just took a good install from a Win 95 machine, copied the whole WINMAD directory and transferred it to the 2000 or XP machine. Then I tweaked the Windows file associations manually. Now I have Windows 7. I tried the same procedure. Most everything works fine, except when I Save or Save As... Mathcad 6.0+ shuts down abruptly. I’ve fiddled with the Compatibility mode and settings, but I get the same results. Any suggestions?

Hello,i am currently making a calculation with Mathcad Prime 9.0, where i got 3 different load cases and i want them all in 1  sheet. i made a few formulas at the beginning, and will later calculate my loadcases with them. For that i wanted some variables to be empty, so that they will just shown as their variable name, so i can later change this variable in every load case to a different number. When i just use a non defined variable, the whole formula cant used furtherWhen i give the variable a value and change it later, it will not recalculate the formula with the updated variable. Is there a Solution for this? Or is this just how Mathcad works?

I'm a mathCAD prime 10 user. I'd like to make my own function which refers a lot of parameters. Among them, here "kinematic viscosity of temperature" is below. The problem here is that TB0 already has a unit, .However, during the process of obtaining detailed variables with "units", it's hard to ignore "existing units" and put "new units". Since parameter A and B both have complex units, I don't want to put complex units to both A and B. I wonder how I could get TB0, with their own units from my program. I already searched on the board and learned that deleting all the units used here and put new units to last values but there're more parameters aside from the attatched files so I don't want it. Please help me out of here!  Plus, I wonder how to set an input variable in a function, lub_app. Please refer to method1 and 2 below.

Hello! I'm Y.J. Kim. mathCAD prime 10 user.  I'm trying to solve a 3D thermal conduction equation in cylinderical coordinate. Does the mathCAD provide 3D PDE solver? Plus, can I get a provided manual how to use it easily? Can I also notice what specific solver  is used in PDE solver? Lastly, I'm wondering how you guys solve 3D PDE by mathCAD. Does anybody solve the equation by FEM with their own script for it? I wonder if it provides so that I could start my work either from mathCAD or python. I always appreciate you.

I am trying to create a push button control in Mathcad prime 10, like a Mathcad-15 file attached here, please help me to create the same in Mathcad prime-10.Thank you.

Hello. I stumbled randomly on the following:It seems that Mathcad defines atan and tan^-1 differently. Look at the attached picture. I thought that atan is the same as the inverse tan but it seems that it is not the case. Please, clarify this for me. Shouldn't atan and inverse tangens be the same definition?

Hi,I am trying to solve a cubic equation, but I am unsure where I am going wrong. Please guide me. I manually calculated the values as follows:x1= 1231.629mm, x2=121.978mm, x3=-153.60mmThe Mathcad file is attached : Mathcad Prime09I tried two different method but not sure where I'm doing mistake 

I'm a mathcad prime 10 user. I'm writing a worksheet for a study material and design check. In manual, its calculated value is a little bit different from the equation above. I wonder how accurate with what significant figures the mathCAD prime 10 does calculation even in every single term in the equation. Plus, how can I get the more accurate result with very accurate single term in the equation?

I'm a mathcad prime 10 user. How can I get results in a column vector Q with respect to each coefficient Ai and Bi? I need to have Q1 with respect to A1, B1 and Q2 with respect to A3, B3? It doesn't really work out in method 1 and 2. The correct result should be the value in method 3 when considering Q1 only. 

Is there a way to ressign the values to a variable in mathcad programming?For example Es is 2.175 and Ec is 3.5 in a loop. Ec is fixed here and iterate Es until MEd is almost equal to MRd. If it doesn't happen then change the values of Es to 25 which is fixed and Ec iterated from 0 to 3.5 until MEd is almost equal to MRd. How to write a Mathcad program without repeating the steps.  

I generated a percentage range from 0 to 100% with a step of 5 percent. Since Mathcad did not want to concatenate two matrices generated this way using the augment function, I created a manually entered matrix. Here, a problem arose because the percentage range entered by different methods yields different results in calculations. What mechanism is behind this?  

So I was working really hard to be lazy and asked google gemini to make a formula for mathcad. It spit out some results, surprisingly, but it didn't work when I tried to paste it into mathcad prime 9.000. It showed some notation that I have never seen before and couldn't find any documentation saying that mathcad can even use it. See my picture attached. Anyone know how to use this "!" feature? Secondly I asked Gemini how to use its output and it said just copy and paste into mathcad, that didn't work, just pasted as a block of text, am I doing that wrong too? Any help is appreciated, or other better experiences using AGI?

Hi,I have been updating a Mathcad sheet and noticed that there are slight discrepancies in the results on the order of 1e-6. I tracked the source of this error and I got to this integral (shown below). There are two things I do not understand:1.- Function A and B are the same but for some reason B throws an error "this value must be an integer".2.- The integral should be equal to 1 when the upper limit is approx higher than 5. But for some reason the solution jumps from 1 to 5e-4 when the upper limit goes from 1.011e4 to 1.013e4, which is wrong. It should be 1. I am using Prime 8.0 Regards,
