Mathcad

Hello everyone, I want to import excel data to a table that has names and units... I'm adding the excel data and Mathcad file.  

Hi,Recently upgraded from Mathcad Prime 5 to Mathcad Prime 8, but when I try so solve an equation containing units in Prime 8 it converts them all to variables and I can't get the answer as it now contains undefined variables. Doing the exact same thing in Mathcad Prime 5 and it keeps the conversion and gives me the correct answer. Am I doing something wrong. and is there any way to fix this?

Hello All, I just use Mathcad prime 8. I've got an issue where trying to plot in the graph and then get a notification (there are too many range variables) as shown in the snapshot below. Could you please help how to solve this issue.   Appreciate your help.   Thanks,Aries

I am trying to activate the 30-day trail on Mathcad prime 8.0.0.0 and I receive an issue of " License service appears to be busy. Please try again." while trying to acquire a license.

Trial license shows to have full functionality, but attempting to utilize a feature there is an error message stating:"This is a premium feature. To use this and other premium features, please upgrade to a full license using the 'Upgrade' button."

HiI have this worksheet.I want to simplify the last equation that they will use r, for example, the last equation needs to see like this: how can I do that? 

The problem is shown as this. I want to get the time domain response resp(t) after sig(t) goes through the transfer function H(s).In matlab, it is easy to realize the time domain analysis using the code:num=[3];den=[1,2,3];[u,t]=gensig('square',20);lsim(num,den,u,t); How can I realize it in Mathcad Prime? Thank you. 

license servers are always busy

I have a function like this.And I want to get the solution when t>2.21. if I use SOLVE only, it get the answer shown in blue arrow.How can I get the answer in red arrow? Thanks.

He seeks out math-based brain teasers and shares them with the Mathcad community to gain the insights of his kind and very intelligent fellow Mathcad users. These include resistor meshes (including in 3D), perfect squared squares, and a puzzle where you must identify the minimum radius on a circle with n number of points where all distances between points must be an integer. Sometimes, he looks for problems on rosettacode.org to solve.   According to ttokoro, many of these problems are unique and won’t be found in a textbook (and many math textbooks in use were written before math software came to

Hello everyone,  I want to K matrix elements as inputs on my curve formula so I can get output of my K values. MathCAD says that "this value must be real.", when I write K as an x variable's value. Can you help me about this topic?

I have a number of formulas that are the same but the variable value are different. For consistency and if just one region is copied to another sheet I'd like to restate the function again. So that if the region is copied to another sheet then I can just changed = to :=. Is this possible in mathcad?

I'm tired of looking back at my work and seeing what did I set my variables equal to. I'm working on bending moment equations for the same beam at different load combinations. For load combo 2 I'd like to calculate the moment at the same spot as I did for load combo 1.. So x_lc2 ;= x_lc1 but I want to see the formula for x_lc1  like this x_lc2:=x_lc1=l/2. I'd like to see something similar to how excel would let you 'step in' to a formula. I know it feels kind of redundant but I just need that visual verification for everything I have to use this sheet for another project. 

I need to upgrade numerous computers, all of which have licenses for Prime 6. We have Mathcad Professional licenses which we get to upgrade to Prime 8.  My questions are.....  What are the steps to upgrade to Prime 8? Do I need a new license or can I use the same license that is on the current laptop using Prime 6? Any help in this matter is greatly appreciated.

Hi Guys,  I am trying to use solver block to find 2 variables. The solver says the solution cannot be found even though the solution exists. Please help me out by checking the constraints. Thanks,

Hello, Everyone.From the following : Plot Intersection-points of the "green" and "pink" ?     Thanks in advance for your time and help.         Best Regards.  

Hi, I'm trying to convert some excel sheets into mathcad,this particular one uses the summation function for variables features to be included, I've set up a table list to define the variables, these are calculated earlier in the document so I didn't want to simply input the values as they could change. I'm having trouble with a fewof things1. if i include beta.yi in the equation it displays the result as a matrix rather than a single answer     a. I've managed to crowbar this to work with beta.y which as it is the same for both values (50 deg) to get a result but i'm aware that this isnt the correct final solution2. the summation results are double what i am expecting, by tweaking the "n" value from 2 to 1 the results match but don't match what i understood how the function should work as    a.      i=1           the starting value of the summation    b      n (n=2) 

I'm trying to insert an Excel component in Mathcad Prime 7.0.0.0, and I keep getting an error that Excel is busy.  But Excel is not running.  I have checked the task manager, and Excel is not open.Even in the list of background processes, Excel is not running.   Read Excel seems to work fine.

I'm playing around with selected elements of a vector, or array.  Suppose I only want elements 2..6.  Why does Mathcad fail when using a range for the index, but defining an index as a range does not?  Curious.Thanks in advance.

Hi!   I have very basic questions and problems with summation operator. Please see the attached worksheet for examples. First question, I'm not just able to understand how the high lighted sum (13) is calculated?   Second example is shown also in the worksheet. How would you use the summation operator so that you could prepare worksheet template and define the n in the beginning of the calculation and then the formula adapts with the amount of n? I mean so that you don't have to change the formula by hands every time the n changes?   Thanks in advance and sorry for the beginner level questions 😣   Br, Harri

Here's what I found in my pantry!Happy New Year!

The best gift for me from Santa is Animation tool in Mathcad Prime! (Prime 10 I hope) My New Year's Story.I don't believe in superstitions like jinxing a person, but...I ran skiing early in the morning on January 1st. A grandmother was walking towards the park and said: "What a fine fellow you are! They are still sleeping, everyone has a headache after yesterday's drinking. And you are skiing!"I went 100 meters, fell and broke my skis! I returned home on foot - the Mathcad does not work! Need to reinstall!

I solved the equation, but I did not like the answer in form. I expected I decided to try the vaunted artificial intelligence portal. Here is what I got. I immediately remembered the sensational story about artificial intelligence, which was instructed to broadcast a football match instead of a human TV-operator. The task was quite simple - to point the TV camera directly at a soccer ball - a smooth round object moving across the field. So, at some point, this artificial intelligence lost the ball, began to look for it and... captured the bald head of the referee, who was running around the field. So TV viewers - football fans until the end of the match had the opportunity to admire the bald referee.  

I am a beginner. When I try to solve a  differential equation problem, the "simplify" tool can not recognize the Sin(t)^2+Cos(t)^2=1. I have to simplify the equation manually. The attach file shows how I do this now. Is there a solution that Mathcad can handle the identity relation Sin(t)^2+Cos(t)^2=1.?
