Mathcad

In the picture that I have added to this post there is an assignment where I have added four vectors.  In method one i have the lenght and a angle, but can I convert it to a coordinate?In method two I have the opposite problem my result Fres is a coordinate but can i convert it to a lenght and an angle?

Hi Mathcad'ers,It's been quite a few years since I last worked with Mathcad, and I don't remember if/how Mathcad could solve a system of equations with intermediate variables.The sheet that I have put together results in an error for undefined variables if I do not place guess values for the intermediate variable. Do I need to put a guess value for these?If I do set a guess value, I get an error that "this value must be a function".What's the best way of addressing this?The details for the sheet are:I would like to determine a,b,o,and q as a function of g and s (inputs).l,t, and p are constants.j,o1,o2,b1,b2 are intermediate variables.Thanks for the help,Raphael

Hi All,I couldn't able to get this solved by Mathcad.Can anyone explain to me why?

Attachments describe my issue.  Goal of program is to extract all relevant rows from a larger matrixCabDataCu for further analysis. The program is set to test for "0" in column 1 of CabDataCu and ifnot "0" extracts the row.   Programs works properly to ignore matrix rows below 5 and extracts 1-5.The problem that befuddles me now is that it misses, i.e. does not ignore or jump over matrix Row4 with a "0" in the first column.  I have tried several variants of the program statements and all haveended up with same result.  Any ideas?

Hi, Please find below the list of the Mathcad applications. Please confirm whether the below mentioned  Mathcad applications are compatible with Windows 10 or not. Mathcad Prime 3.0Mathcad 15 MO30 If the above versions of the Mathcad applications is not compatible with Windows 10 ,is there any upgraded version available for the above mentioned applications which is compatible with Windows 10  & will there be any cost incurred for getting the latest version of the application?Could you help us in this or please  help us in getting connected with the concerned person as this is a priority thing. Your response helps us in proceeding forward. Regards, Juhi Minsu Majeed

  Hi Helpers, The attached Mathcad Worksheet computes correct results.  It might appear long/complex.  However, the questions relate to the simple input of two variables at the very top of the worksheet and the simple 3-line Given-Minimize Block at the end of the program.  At the top of the program, the D and t arrays are parameterized with parameter OD1, OD2, and WT1, WT2, respectively.  Specific values of these parameters to minimize the function “weight” are sought in the Given-Minimize block at the end of the program.  Here are the questions:All parameters (i.e., OD1,…,WT2) must be provided explicitly in the minimize function of the Given-Minimize block. Array of parameters are not allowed. Could you please confirm and comment?All parameters (i.e., OD1,…,WT2) must be provided explicitly in all embedded subroutine calls in order to be optimized.  (e.g., Ao, which compute the gross section area at the top of the worksheet.)  Could you please co

Recently i got a question while using the mathcad file .my question is why calculating result is different between excel(before using exel solver's optimization algorithm) and Mathcad(before using Minerr function)? I know that after computing an "exel solver" or "Minerr function" their value would be apparently different, because excel solver is using an GRG algorithem and Mathcad is using other algorithm such as Quasi-Newton.  It looks same at a glance, but if you see carefully, their values are not same. And of course i put the same 18 parameter values in excel and Mathcad.

I am using Mathcad Prime 3.0 and I can't find how to paste inside a text block as plain text from i.e. Word to Mathcad.I was unable to find anything in this blog or the help documentation. Thanks!

Hi,I am a new MathCAD Prime user and I was wondering if it was possible to store frequently used equations so that I could call them back on screen. For example, if some one was working on fluids projects, they could insert the Bernouilli Equation easily without having to retype everything. Ideally this would display the equation and all the variables to enter known data into. Also, is it possible to insert data tables and interpolate between then as in a thermo problem requiring steam tables. This would be a great help to students. Thanks!‌

Hi, everybody.I met with an issue on solving for flue gas temperature which is the upper limit of an integral within an equation.but when I deleted some items in the equation, the answer can be given by the solver block.I m confused with this for a couple of days. Is this caused by the unit system? It seems that using dimensionless numbers takes effect, but this is not very convenient.The attached file is in mathcad 15 format.Does anybody give any suggestion on this problem?

  Hello, Everyone.  The Question is : What is Irrational Number for "?"   ?      Thanks in advance for your time and help.           Regards.

Hello,Could anyone help me to sort the output of my attached program so I can plot I(k0) when x-axis is "d" and y-axis is "theta" ?thank you very much in advancePayman

  Hello, Everyone.  The Question is : What is The Irrational Number Representation for " ? "    ?      Thanks in advance for your time and help.           Regards.

A tuning fork vibrating at a frequency of 512 Hz is held over the top of a jar filled with water and filled with a tap at the bottom. If the jar is 60 cm tall and the speed of sound is 350 m/s, determine the possible resonance position(s). neglect end correction. I calculated lamba =v/f. but then got stuck after that.

I am solving a system of ODE's. Solutions look good (I am checking against plots in a book) except when I plot two of the output functions against each other to get a phase plane plot. Changing range of axes does not seem to help. Range of axes does not correspond to range for the individual functions. What am I missing?

Hi All, I have a time domain signal, which is formed by a triangle discharge current to the series connection between a resistor and a cap. Would anyone told me how to find out the max and min value of this time domain piecewise signal? A simplified worksheet is attached. Thank you!

MathCAD Prime 3.1 crashes on activating "Text formatting" font style dropdown-list and typing in the font name.  This depends on whether I have opened an existing document or a new untitled document. After the crash, the recovered existing file is corrupt, and all unsaved changes to the original document are lost.  Mathcad Usage‌PTC Mathcad‌

Hi All, I have a circuit like this, where I want the components value R1,C1,R2,C3 and R3 as the user inputs.I can list the equations to solve this circuit, but I do not know how to realize it in Mathcad. Would anybody help me?I have attached the worksheet. In addition, if this circuit can be solved, can we also add a control button, to "trigger" the Mathcad calculation by clicking it?Thank you!

Hello everyone.I'm having a problem solving a tiny equation with units and hope you can help me find where I go wrong.As you can see on the picture I get the right answer if I isolate Alpha myself, so I'm guessing that its how I do things that is the problem.Sorry its in danish, but its says "Angle acceleration under breaking of a flywheel and axel"The values on the top are defined further up in the document."I" is inertia.

Hi community,sorry to disturb you and for the lack of skills in english, but i'm a grateful user of the program Mathcad 14. We are a hole group of students in Denmark, who wonders if the calculation service in the program can show the equation with the specific numbers used in the equation? The new policy rules in the Danish education environment demands numbers in the equation, but we can't find the specific settings to change this problem. We have made a well-functional template in the program, so we are in desperate need of help to change these settings.Best regardsPeter Weller Nielsen

Can you create the curve in X-Y plot?More simple curve

Hey,can anyone explain me why i have not enough memory to perform a mathcad calculation?(I have 16 gig and my college has 32 gb RAM) on both mashines mathcad calculation is not possible.Indeed its a hugh calculation with a table goes from A1 to ZZ99Is there a restriction or limitation in Mathcad itself?Thx

I have a program that uses the Find(x) function to solve for the allowable length of a beam whose design is based on a series of moments and shears.  The file attached is a very simplified version of what I am trying to do in the actual program.  One of the constants (in this case y) is a vector of fixed values.  I want to solve the system of equations for x using the three different values of y and store each of the results for x in a new vector.  Can someone assist me in developing the correct notation to get the desired solution?Thanks,Derek
