Mathcad

Hello, I am solving a circuit equation in Mathcad 9.0. I want to express the above equation as cos and sin identities (Basically expanding Euler) .I want the equation to look like U/I form .     

HOW CAN I GET INTERPOLATED VALUES OF KN AT DIFFERENT ANGLES AT A CERTAIN VALUE OF DISPLACEMENT? 

Hello,  

 

Hello Everyone.From :How to fill the ( convex, concave, complex ) quadrilateral with color ?Thanks in advance for your time and help.Best Regards.Loi.

Hi everyone, I have the following table as seen bellow in the attachment and my problem is that I have to extract alphax, alphay, betax and betay based on the value of lambda. Is there any way mathcad can do this on it's own?Thank you in advance.    

I am trying to solve a simulation of blowdown of a pressure vessel and have defined the ODE's but there is a glitch I cannot resolve with a variable undefined error. I am sure it is a trivial error but if anyone can assist I would appreciate it. Mathcad 15 sheet attached.Thanks Ross 

Hi all,I'm new to Mathcad and trying to do somthing that is very simple on Excel, and hopefully isn't too difficult on Mathcad-I have a range variable say z:=-5..5I have a complicated function f(z), but for simplicity just assume it is - f(z):=z^3I would like to have a matrix where the first column is z, and the second coloumn is f(z).It should look something like that--5-125-4-64-3-27-2-8-1-10011283274645125 Any ideas/suggestions how to do it?Thank you 🙂 

 

Hi I am a new user and running into an issue.  I defined a variable outside the solve block and in the solve block set up odesolve with the function in the ODE.  However, I get an error in the solve block saying variable not recognized.  Please let me know what I am doing wrong.

I have installed P9 along side P8.  Some things to note: P9 is not downwards compatible.  I inadvertently saved a sheet in P9 and could not open is P8.  You can copy and paste but only parts.  This should have been made clear in my opinion.P9 HTML help is now PTC web based.  This is of no use if you do not have internet connection or working in a controlled environment. I think this is a poor approach.  the user should be given the option at installation.AnimationThere is some silly plot animation that was installed.  I honestly have no idea what to do with this.If this is an emulation of MCAD animation, this falls very short.Some explanations at the installation would be valuable.Other than that, its the same software as P8 with all its resident deficiencies such as plotting, searching etc. etc. Regards,  

Hello, I've seen this question asked previously but wanted to get some additional confirmation. We are planning to update our license file to allow Prime v9 to be deployed to our users. Will the updated license file for v9 still allow Prime v8 to run? Or will that run on Express mode and not have access to our license?  

Hi,Can you please help me to convert these xmcd files to mcd. I'm using Mathcad prime 9.0Thank you very much.   

 Dear Mathcad veterans, I'm doing a linkage calculation / kinematics calculation using co-ordinates (x,y), for which I would like to know the methods of finding co-ordinate's new location (marked as position 2, 4 and 5 in the below representation. Please share your views or directions or solutions. Best regards,Ram   

there is a problem in finding the solution of the equation in given below due to change in change in value caused by unit tonnes automatically gets converted to Kg. 

Hello All, I am trying to generate a 3-D plot for a function. I am having the following issue.  Please help.  

i  am trying to download the 15 version and its giving me  diagnistic tool  

Unable to use solve block to find the result. Am i doing something wrong? Please help  

I've shaded a portion between markers and curve as one portion as a other as b, how can i find area between them. 

Hi all, I am trying to perform a 4 parameter logistic regression using genfit on a data set in Mathcad prime 4.0. I already have done this regression online, so I know what my guess values should be. I just want it for Mathcad workflow. Unfortunately, I am getting a real number error, even with close guess values. Is there any way to see the domain of these guesses? I hope this isn't a rendundant question to the site, and I've attached my document to look at. Thanks a ton in advance!(picture if needed)  

Good afternoon, I am sure this is simple but cannot find an answer. What is the most direct way to delete an else block that is empty?  I really struggle with this.  Am I missing something? 

I converted worksheet from 15 to prime having minimize keyword. Giving different result after conversion are there any changes that is required to do in worksheet. 

Hello, I'm new to mathcad (express prime 9.0.0.0 and have full functionality for another month), so extra points for being extra articulate 🙂 The image below on the left is what I am trying to accomplish and what I've typed out within Mathcad. The image below on the right is the book example I am trying to replicate. I am trying to plot Fr_eff/X vs X with different "p" values, which makes sense when looking at the text. Some Questions:Why is the error "trying to plot to many range variables showing up?"In the example textbook they are showing the function they are Plotting "Fr/X". How are they plotting the function without writing the inputs to the function, ie. Fr(X,p)?They are only plotting p=0.5 up to 7 (in increments of approximately 1 in certain cases), which is not how they define p at the top. How are they only plotting certain p values, and not all of them?Last and obvious question, what am I doing wrong?   Thanks EDIT: I've at

Good evening,I am trying to solve an exercise in MathCad prime 8.0 with the RKadapt function but it return a very unusual error that says "Unknown error: Exception generated by call destination", I have tried to change the function with "Adams" or "rkfixed" and it returns the same error, I have also tried to redefine the equivalences as for example "(d/dr)^2 y(r)1 = y3". Attached there is a screeshot of my work sheet with the differential equation that I need to solve and the procedure that I did.Thanks to everyone in advance.    

Hello,I plotted this function and the graph looks something "strange", at least at first glance. Normally it should have shown a continuous line, or? MC8 Prime.
