Mathcad

Hi everyone, This is David Maloy,It has been a long time sense I have posted a "Help request".Ihave a problem with a formula and MathCAD Prime 3.1.My goals. I need to rearrange the formula so that the equation is set to solve for the "h" value.Thanks in Advance...Dave Maloy

Sorry, I am not a Mathematician.What is it the second root? See please the picture and Mathcad 15 sheet in attach.Same in Maple

See please the Mathcad Prime 3 sheet in attach.One transport problem - see Prime (with me) cannot solve a transportation problem

This study continues the analysis of problems of optimization techniques using the example of staged evaporation of steam in the boiler drum to reduce the concentration of impurities in the steam from the boiler. The described techniques use mathematical packages and spreadsheets to solve the paradoxical problems of optimization.Fig. 7.1 Site for calculating staged evaporation in a drum boiler  Fig. 7.2 Create user functions using Mathcad symbolic mathematicsFig. 7.3 Numerical search of the optimum  Fig. 7.4.

Hi,Is it possible to display image with if conditionI would like to display the right side image if the left side condition is satisfied.Could you please advise.BR,J.Randeep

I come across these type of equations all the times where I have to find a variable displayed on both sides of an equation and if derived can lead to a quadratic or cubic.However I would like to know if there is any way without deriving the equation, to find the value for me? I try to do this but it does not work. see image below.I also would like to Know if Mathcad does algebraic operations and can cancel out variables or convert complex equations into their simplest forms?Thanks

Hi All, I have a simple summing circuit. Two sources  are the inputs via two resistors to generate a weighted signal Vref. Then this Vref is multiplying by a constant number "ratio" to get a Vout. The details of my circuit can be seen here:My target V1,V2 are within 0 to 5.3V, and target 10>"ratio">1, and all resistors should be between 10K to 1M ohm.  Right now I am not able to use if condition to solve the equation array to figure out what V1,V2,R1,R2 are. I have uploaded my worksheet in the attachment. Would anyone teach me how can I calculate these values within the reasonable range, by maintaining the other two parameters "ratio" and "Rsum1" within their reasonable range? Thank you!

‌How you are read and captures an image directly from a camera to be processed in mathcad. The idea is read images within a sequence of programming and process each image captured with a target particular.

Is there a way to avoid the error (Mathcad 15) when I delete (which is very common) the brackets in the denominator?

Is there a way to lock certain cells in Mathcad 15?I am creating a calculation template and want to pass it on to coworkers, but I want to lock certain cells that should stay constant so they can't be edited without a password or something. Is this possible? I only see how to lock the entire file or all of the contents.

How do I make headings in Mathcad like I do in word?

Basic question to format my results to show "+" sign when the result value is positive. My field of application is in structural analysis. Thus, when the Margin of Safety is positive, the "+" sign is preferable to show the positive margin.Thanks.

Hello, I'm having a hard time to find 'L' using a function - please find the attached file. L should be around 7. Thank you very much! MJ

Hello EverybodyI use MATHCAD PRIME 3.0.Does some one coulp help me with the syntax to set a value to a matrix' element in an array of matrix?On this example AA is an array/vector of 2 matrix 5x80.I can access to an element to get his value (67.34) but I am not able to set a value to this same element.Maybe the syntax I use is incorrect..Please Help !!!

I have issues updating results. No matter how many times I hit ctr+F9. I have tried moving the equation above the predecessor and sometime it works but sometime I have to close the application and seems to solve the problem.Please see attached.

In Matlab, when I plan to extract a submatrix from a large matrix in the following situation:Say I want to extract row and column 1 and 4 from K, I can create an index matrix and do this:idx = [4 1; 1 2; 2 3; 3 5];k = K(idx(1,:),idx(1,:));But in Mathcad, the built in function submatrix can only extract continuous row and column ranges.Is there a way to let Mathcad do the same job as in Matlab?BestShawn

The mathcad is unable to solve definite integral to yield array output. The input is also in array form. Even if I put limits in the closed form of integral it yields only a single value instead of array. Please solve this problem. The integral and other steps with problems are highlighted.

I'm sure this is pretty simple but for some reason I can't make sense of the help files.  I'm not sure what the proper terminology is so here's an example of what I'm trying to do:  I would like to have Mathcad tell me that f = .055P  (i.e. P/18).  How do I do that?  Right now it tells me that P is undefined; do I just need to define it, and if so, how do I do that?Thanks in advance!

I would like to use in my Prime-sheet time units ns (nano-) or ps (pico-) from the list of built-in units but:Is it a bug?

Hello,In the derivation of the Gamma function, in its integral representation, you get an unusual result shown in the figure in the green rectangle. What to do to not generate it?The result is correct, but the fact that Mathcad, in representing the generalized integral with the limit, has changed the variable of integration, assigning any, in the example X253, surprises me somewhat.Thanks for the attentionWith best regards

Hi.Is that an usual thing for define a variable?Thanks in advance.Alvaro.

Hi.Can't find the "how to" do for this two simple questions:1. How to format a label, from this help page:2. How to create a new label, from this other help page (blue highlight says that "You can also define your own tags or force a different label on a particular item."Thanks in advance.Alvaro.

   Hello, Everyone.         1_ Is there a reason for "Illegal Assume constraint" ?         2_ Is there an other way to assume for obtaining : P(a,b,n) ==> 0 ?    Thanks in advance for your time and help ?        Regards.
