Mathcad

I know a and b of an ellipse. What is the value alpha of a circular cone?

Hi all, looking for some help to solve the following equation (circled in red) to find one of the limits of integration (b). R.d is the other limit of integration which is fixed and known. The angles 'alpha' and 'beta' are known and fixed. w is known and fixed, q is known and fixed.    Angle 'theta' varies with r and b.   Any help would be appreciatred - currently trying to do it in mathcad 15 but i also have access to prime

Hi,I'm having the following issue with the units in mathcad15:L:=20.76mThen when I go to repeat L later in my sheet it comes out as L=0.Anyone got any ideas how I can solve this issue? I'm having the same problem even when I change L to Beam for example.ThanksMike

I am working on a project that requires a lot of text to be imported in a Prime 6 worksheet.  The text is reformat and saved to a Excel worksheet to improve its presentation.  This is pretty straight forward as shown on the attached PDF file.  (The Prime worksheet and support excel files are too big to post).  In going through the string commands, there is an option for new line command \n.  I have seen this in other programs, but not sure how to use it Prime.  There may be cases for it use.

Is it possible to get a more clear result, and how can I solve the two angles ?

why can I not solve this ?

Hi, Does anybody know how to get different eigenvectors of matrices with two or more equal eigenvalues?  The standard Mathcad eigenvec function only gives the same eigenvectors.   Thank you

Does anyone like this topic? Images are ipg 120KB each.

Still using MC 11.2, which (for me) is fine.   I was wonder if  a function which is not explicitly expressed, can be used in a symbolic operation. Maple and Mathematica I saw can do it quite well. Below an example with derivatives.     It seems that only n.1. works while the others (I am in fact interested in a function f(y/x) do not. The n. 3. solution seems incomprehensible to me. Does exist a trick to make possible to solve for instance function n.2 symbolically? [[Sol: f(y/x)-[y*f'(y/x)]/x  ]] Thanks.

Using READPRN in MathCAD 15 I found that it's limited to 2,000,000 rows. Fortunately READFILE doesn't appear to have this limit as I was able to use it to read 2.7E+6 lines of a text file.

I'm often provided with a flow rate, but it can be specified in either volume flow or mass flow.  I want a simple way for my sheets to work regardless of what is specified (i.e. calculate the one that isn't defined from the other).  My goal is to have the two inputs, but the one I don't need is disabled.  I thought this would be easy, but I'm not finding a solution other than to enable/disable equations (which could get messy and dangerous) or assign flags telling mathcad what to do (also dangerous).  In excel I could use ISNUMBER or similar, but I don't seem to find that in Mathcad.  I thought TRY would work, but even that quits when it reaches an undefined variable.  I tried a few things with NaN but still no luck.  Any suggestions?  Thanks.   4.0 attached.

Hi ptc community, I would like to make the following arrangement:   c="aply" a:5 b:3 c≡if(a>b,"aply","does not aply")   Is there any way to place a result of verification of several variables before said verification?   I know that the global definition makes two passes: in the first pass, it evaluates only the global definitions and dismisses all the regular definitions but it would not be great if in the first pass it evaluates the global definitions taking into account the regular definitions that are before this global definition so that in the second pass not have this problem?      

Sorry, what is it TOL and CTOL?

Hi everyone Please can one write steps for estimating the exponential distribution param using Markov chain Monte Carlo simulation method in MathCad. Thanks Alot

I have no idea what im doing wrong as usual with Mathcad. I have been forced to go back to Mathcad 15 because i no longer have prime. Why am I getting an error that says undefined variable.   I am defining a few variables above that are hard set               Defined above Rin:= 100 DeltaV := .04 Intial Guess out:=100 given V = DeltaV * (out/Rin) Av = out / Rin find (V,Av) = And all i get is variable undefined               Im sorry, I don't know why it wont let me post the code. The sudo code is above I have double and tripled checked syntax. I am obviously not getting this. I absolutely hate 15 I can do this in prime with my eyes closed  

To all, I had to re-install mcad 15 (M050)  on my machine. Two issues I am having 1. I cannot save the file. I get an msg: 'filename.xmcd is in use' Save with a different name.     Clearly it isn't (it's a test)!! 2. Any existing files are open read-only. I have full access to these files   Any idea what is causing these issues? If 'yes' how do I fix them?   Thanks Regards

Hey I have a question. Since I am still quite new to this software, if you think my question is easy, please help me out. Suppose I have a value calculated at the end with different parameters. Wondering if there is any way that for each parameter, I can create a matrix or excel with two columns, one is the parameter number, and the other is the corresponding value, when keeping others constant.  Thanks a lot!

Hi,  I'm starting in mathcad and can´t solve a simple problem. I have a function  f(x) = 6.08 - 5.11*x + 1.04*X^2 and I have a matrix with many values of f(x). I would like to create a matrix whose rows are root of equation f(x). I will attached the matrix of f(x).   Thank you
