Mathcad

I'm having trouble getting a minimization function to work for my HETP graph.

This works just fine in a fresh worksheet; however, in my more complex Ballistics worksheet, I get the following error. Both worksheets are attached.Even if I close and reopen the ballistics worksheet, the problem persists.😫Thanks for any help.Reg

Hello, Can someone tell me why Mathcad isn't able to solve this simple variable? This command works everytime but with these types of equation it doesn't:  I have tried other commands but it still doesn't work:   The solution is quite simple, but I would like it to do it automatically:   Can somebody help me? Sorry if there are mistakes in my english. Thank you. 

Hi Folks, I'm converting V15 files to run in Prime 8, but can't figure out out to remove the red arrows and red lines.  The file runs.  Right clicking on the arrows doesn't do anything.  I can't find anything in the online documentation.  I must be missing something.  Can anyone enlighten me? Thanks, Mark files using the converter in Prime 8.  

Is there a procedure to use the data from an referenced Excel file or matrix to populate a combo box? Thanks,

I'd like to specify a matrix size and have it filled with elements from a vector. For this example, I have a vector containing state names and I want to have them fill a 7x4 matrix. I'm running into 2 issues with the attached sheet:I'm very rusty on programming and matrix operations, so the only way I've been able to fill a matrix at the size I want is to reference the specific elements of the vector. I'm sure there's a simpler way to do this using a loop but I haven't been able to figure it outIf the vector changes size, I'd still like to be able to output a matrix with zeroes filling the rest of the nodes. Currently, if I set up a 7x4 matrix and the vector only contains 16 states, the output matrix errors outAny help with this would be greatly appreciated!  

Hi,we have MathCad 7.0 and MathCad 8.0 in use at our school. MathCad is licensed from a license server. For both products a floating license is specified on the license server.We want to restrict the access to the license server as far as possible by a firewall construct. Unfortunately MathCad does not only use port 7788 when issuing licenses, but has many other ports that are necessary to reach the server.Using a live view of our firewall, we were able to track which ports MathCad needs to reach the license server.Unfortunately, the port is always different, so even allowing a small port range is not possible. We noticed some ports in the range of 48000 - 57000, but unfortunately all of them are always different. Sometimes some at 49000, sometimes some at 54000, since today some are in the range 56000.Is it somehow possible to limit the port that checks the reachability of the server or to fix it to one port?Error message down below....  After changing the port in the firewa

My calculations fall over when I change to inches. Prime 8 Used. Then won't work when I chage back to cm      

Here a dispute arose.1. Is this closed curve (a phase portrait) an ellipse? The ellipse has two foci. How to calculate the abscissa of the focus of this "ellipse"? 2. Can this object be called a curve? The curve has a length. How to calculate the length of this curve?

Currently I am using excel for all my design calculation. I wanted to know if mathcad is better and how is it better. 

I have a solver block with an equation and a functionFurther down the worksheet I define two ranges of values, x and Vb. Both ranges have values in the range 0-20.  g(x) returns values but g(Vb) shows as I am attaching the worksheet and an Excel workbook which contains the expected results.I would also like to use WRITEEXCEL to output the values of x and g(x) but I can't get that to work either. 

I have 16-bit TIFF images I need to analyze.  But, it seems that Mathcad Prime 8 (and 7 before) only reads them as 8-bit.  Mathcad 15 read them correctly to their full bit depth, but Prime does not.  Does anyone know how to read 16-bit images to their full depth?  (I also have 12-bit JPGs with the same problem, Prime reading them only as 8-bit.) Thank you, KK

Helping an old man with fading memory would be much appreciated.In the attached Mathcad 15 file, I have somehow enlarged the label fonts.  I cannot recall how I did this.  Can anyone find the setting I used to change the 2D graph fonts? Thanks for any help.Reg

How do I continue an equation on the next two or three lines if necessary?

 so it says my units are incompatable but they are unitless 

I can't figure out why the first equation in the picture does not work, Mathcad says "These units are not compatible." The units of M.w.mid are kip*ft, and 8 is dimensionless. There are no matrices in this spreadsheet, but for some reason the dot/multiplication symbol is acting weird, or like a dot product. I don't really want to use either of the middle equations, because they don't match AASHTO, but if I have to I will. For reference, the correct answer is 103.0kip. Mathcad 15 also returns 103.0kip without a dimension error. 

I am trying to create a vector with values like this1, 2, 3, 4, 4.2, 4.4, 4.6, 4.8, 5, 6, 7, 8In practice there will be many more values and it wouldn't be practical to enter them one at a time. If I create three vectors like thisv1 := 1,2..4v2 = 4.2,.4...4.8v3 = 5,6..8Is there some way I can combine them into a single vector?Also, I would like the resulting vector to be a row vector rather than a column vector (if that is possible).

Hi, is there any chance for me to make contour plot which will look the same as the  A-B plot I sent you, but I want that the greater the value of member of array C for designated position is, the color of point for that position would be closer to red (classic contour plot with rainbow colors). Best regards and thanks in advance.

Hello, In 1594, Adriaan van Roomen set the task of determining the zeros of a polynomial of degree 45. This was quickly resolved by Vieta by taking a close look. One quickly discovers that the sine of 45*x is to be expanded by a polynomial in sine(x). I tried to understand this in the attached file. Mathcad 14 went on strike. I am asking for hints how to expand the product in attached file for n=45 into a polynomial. Mathcad drops out at n=11. Kind regards, Alfred Flasshaar

Hello everyone, I'm having some big problems trying to solve a finite element method problem for my class. I am trying to determine a stiffness matrix for a problem I was assigned and this requires me to double integrate an 8x3 matrix, a 3x3 matrix, and a 3x8 matrix. I get mathcad to perform the matrix multiplication to give me an 8x8 matrix, even though it says the symbolic value is too large to display. However the issue is, I cannot assign a variable to the result that I am got, I do not understand how to get this to work, when I know mathCAD should be able to do the computation. Below attached is the exact solution to what I am talking about. Please help!    

Hello, I need all of your help I have previously tried to make a graph line, all the formulas have been defined as well. But when I make a graph, the line of the graph doesn't appear as below, can anyone help how to fix it?   

I am using Mathcad Release 15.0 and DatecodeM050After MS Office migrated from 32Bit to 64Bit (on a 64Bit machine) a visual studio object script embedded into the MathCAD sheets is not available anymore. As a consequence MathCAD15 outputs an error message "Cannot launch server application". This omits scrolling and other work in the sheet so that in the end it is unusable.

Hi, When using the symbolic substitution of an expression for a variable in an equation, the order of the variables is getting switched by mathcad 15, which is only version of mathcad I use.  How do I prevent this from happening? for example y=x-az=y+bwhen I copy expression x-a and select y in the 2nd equation & use the symbolic substitution from the pull down menu off the tool bar, the new equation for becomesz=a-x+bwhy is the expression x-a getting multiplied by -1 when it’s symbolically substituted for y in the2nd equation? thanks in advance  for the helpful! 

I would like to plot (to animate) an oval - an ellipse with one focus as a point and second - an ellipse. See about this problem Symmetry | Free Full-Text | A New Ellipse or Math Porcelain Service (mdpi.com) But I have problems -  tee pics and Mathcad 15 in attach. One solution in SMath So, an ellipse and a hyperbola can be specified either through a focus with a directrix, or through a pair or more foci. But the focus can be not only a point, but also... a circle, and an ellipse and a hyperbola can be crossed and get an ellipsohyperbola.Figure shows a family of closed curves, which can be called these same ellipsohyperbolas. These are ellipses, in which the first focus is a traditional point, and the second focus is a circle. Outside the circle we have ordinary ellipses, and inside the circle we have branches of a hyperbola. This can be verified not only visually, but also mathematically - inside the circle, addition (ellipse) turns into subtraction (hyperbola). The ellipse
