Mathcad

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

Mathcad has many functions and constants named after mathematicians and scientists - Chebyshev, Runge, Kutta, Kelvin, Sinus, Ampere, etc.But I did not find there the name of the greatest mathematician - Euler. We need to fix this and make the Euler function built-in Mathcad for the simplest numerical solution of the ODE.Especially now, due to the high calculation speed, there is a return to simple algorithms - KISS!

I am new to Matkada prime, I have a problem with solving problems when I put symbols (explicit, all), I have a lot of numbers in an explicit expression after the comma, how to reduce them to at least 3

Hello, I need some help solving this problem: Given matrix A(n,m). find the row with the most negative elements and replace it with the row with the largest element of the matrix.   Thanks!

Hello,I want to plot some functions:   And the function f2(t) should look similar to the function f1(t), not exactly, but something like f1(t) looks.   The problem is that the graph of the function f2(t) is displayed only when I increase the time axis so much (10^1, 10^2, 10^3, etc), which is a bit much because I want to see this part (see image below) from the beginning as it looks, not a straight line   And not like this (see image below), because I want to be able to see the transient/beginng part much more, how will look (like the image shown above) Good: Bad Bad   I would like, if it is possible, to plot both functions on the same graph and to be able to see the beginning part for the function f2(t) just as I can see it in the case of the function f1(t)   Mathcad Prime 7 file attached.Thanks.  

Hi all,I need your help.I have an old calculation, which was made in Mathcad 14. This calculation was made not by me.This calculation perfectly works in Mathcad 14. Now we have Mathcad Prime 7 and 8.I have converted this calculation to  *.mcdx format. And I got a problem.The equations, which calculated using Euler method, cannot be calculated now in Prime 7 and 8 with step  5000 and more.It show me error “ infinite recursion or overflow”.With step 4700 it still works. Attached you can find this equations. Thanks in advance.

Hello.Could someone help me, please, with this task? An error while trying to find Symbolic solution of a system of linear equations with specific accuracy. What I should do make it done?

Hello All, I am relatively new to MathCAD and am having an issue developing a set of symbolically solved equations for a system. I have assigned values to the variables however throughout my analysis I would like to solve or simplify equations ONLY symbolically for a particular variable and KEEPING all variables as symbols, NOT replacing them with their numerical values.Is this possible?
