Hello,i am not sure why the x and y values are so large in the graph. Thanks!

Mathcad 3.0 I am trying to set the width of the header independent of the width of the body of the document. Is this possible? It appears the header size is dependent upon the margin size. If the margin size is set to narrow, the header is very short and appears not to be able to be adjusted. What I would like to do is set the document body for narrow margins with approximately 15 lines of text capability in the header. Is this possible?

Hi all.I am trying to write a program that will increment a value of x by a predetermined amount, run through a few equations, and then re-evaluate that condition. If that condition is not met, return the value of x to H_loop.I have attached the program, "loophelp". You will have to change the line in the program "H_loop" from "STDD > STDD_allow" to "STDD < STDD_allow" for it to run.I wrote a program that was very similar in structure to the right of the program I am having trouble getting to work. I am not understanding why that one runs with no issue, but the one on the left will sit and spin its wheels ad infintium.Thanks for any help.-JW

I finally success to calculate my work by using "vector"SO I want to say "thank you" for all people that they helped me.After calculating, I did read data "CL" by using "if" in case of each conditions.I got strange values that I couldn't understand.so I writing this site about my problem after truble.could you give me advice for me?

Hello everyone.I need to create matrices formed by a variable number of columns of data extracted from a table based on input values. Attached is a sample sheet so you can better understand what you want to achieveThanks in advance

2014-11-25:  Minor update.  I don't know why I was defining "Case" the hard way.========================Streets with curbs and gutters are a key component in the overland conveyance of storm drainage.  The purpose of the attached documents is to estimate the hydraulic capacity of one-half of a street cross-section for various conditions.The attached .zip file contains five documents:  two Mathcad Prime 3.0 worksheets, Adobe .pdf copies of the two worksheets for users of other versions of Mathcad, and an Excel spreadsheet that nearly duplicates one of the Mathcad worksheets.  The genesis of these worksheets is a vintage 1989 SuperCalc 5 spreadsheet that I created for a storm drainage master plan.  When I decided to create a Mathcad version of these calculations, I decided to also update and improve the spreadsheet in Excel.  Although this added quite a bit of time to this process (creating nested IF statements in Excel to mimic the two programs I wrote

I got advice to use "vectorization" But I wonder something.I saw the book and I knew that "vectorization" is just possible to calculate about same raw and column.But I need to know total calcuation values. For example a=0,1,2,3,4,5 b=1,2,3,4,5y=ax*bif I caculate by using "range variable", I get total calcualtion values. in case <a=0,b=1> ,<a=0, b=2>.....<a=0,b=5> <a=1,b=1>, <a=1, b=2>.....<a=1, b=5> . . .<a=5, b=1>, <a=5, b=2>......<a=5, b=5>I want to get values following.I couldn't have used "vector" because I thought that I couldn't get it.

I could success to express theta look like "range variable"But I can't get "alpa"I guess the reason why I can't get values is due to "beta" I got error. error said me that the unit is not compatible.so I don't know which is wrong.

I am doing some strain evaluation for dents in natural gas pipelines. I am looking to interpolate matrix to generate a larger matrix with more points. I am not sure how to go about doing this in mathcad. My Matrix can vary in rows in and columns based on the user input. For this example 18 rows and 85 columns. Essentially I am looking to have more data points in order to evaluate the dent geometry.

Hallo.I have some trouble with this.I have to find the polar notation and rectangular notation.I can find the answers from my normal calculator. But how can I type it in mathcad, and solve it there?The answers are 340∠-10.9 and 334-j64.3

Hey,at the moment i´m calculating the massstreams in a powerplant.For the calculation there is a for-loop necessary because one of the last streams is going back to the beginning of the calculation.My problem is that the for-loop will not be calculated while using Units (like kg/hr or mol/hr).I added a simpel example which should discribe my problems more accurate.The output of for-loop should be a Matrix with different Units like [kg/hr] for the Massstream and [ ] (no Unit) for the iteration number.

Hi,I am trying to install mathcad 15 free 30 day trial, but I get an error when trying to obtain a trial license.Invalid host id errorAny help appreciated

Hello, I having a problem with Minimization with 6 paramaters. I have attached the worksheet. i am not able to find the problem. Its calculating, but it doesnot bring the answer. Pls kndly check my worksheet. Thank you

Hello,I a'm a student and i need help witch taskGiven a triangle defined by 3 points with coordinates(x1, y1) (x2, y2) (x3, y3)Determine the center and radius of the circle of the triangle. Draw a triangle on a graph and a designatedcircle.i don't understand this sorry for bad english

Hello,I have an equation with one uknown on both sides and would like to iterate to get the value of variable, however the find function brings error, I think I am following others recommendations (several youtube presentations) but still no result. I have more equation like this to solve and would really do with advice what I am doing wrong.I am new to Mathad.

Hi,I am attempting to solve a linear system with mixed units, but I am having great difficulties. I have read that 0's within the matrix must have assigned units. However I still get errors.Worksheet attached - linear system on page 2.Working in Mathcad 15Any ideas? Thanks

Hello,I am having trouble using the solve block, specifically the find function. I am completely new to this, and have tried researching on and double checking variables, but I cannot seem to find the problem. I have attached the file.Thanks for any ideasEDIT: I am running Mathcad 15 trial on W8.1

Hello everyone,I am trying to create a plot to find the critical phase angle affecting a pipe.When I created the calculation in Mathcad15 everything works fine. See the file attached.When I reproduced the calculation in MathcadPrime3.0, I am getting errors such as "the variable is undefined", "plotting failed", etc. See the file attachedCan someone please let me know how to fix the MathcadPrime3.0 calculation?I am having trouble calculating the lift of drag force for several values and then using these to create a plot. If input F(4) or F(6) everything is fine. But if I say F(x), and x is a matrix with several values, then the equation crashes.I would really appreciate your help.Thanks!-Ritchie

Hi guys,Can you please help me with the following problem. I am not an expert in mathcad.i want to draw "t" vs final "finalCoOEPcon" in the attached mathcad sheet and Mathcad keeps giving the error that the "value must be real" which i believe is real.so i have two questions:1- is the way that i wrote the "equation A" is right in mathcad for solving for "t"? 2-can you help me with some hint that how i can make this curve please?thank you very much

Hello,I'm wondering if it is possible for MathCad to do an optimizing routine using max or min but with a given set of parameters. An example is one of the attached in where I use u(x) and g(x,r), where I want to allow for the input of r during the optimization. Additionally, would it be possible to graph the optimized set as a function as well in terms of a variable x & r. (for any given r, the maximum x is a set value as the rest of parameters are just scalar values, thus I would like to get the optimized value of x as a function of r) I'm assuming the opt x for a given r can be done via a vector output from a solve block routine as a function?

I don't know well wht I got error cotinually. I am shy to post often.

For example, is it possible to track red line on green line?I searched some site to know it.But I don't know well, is it possible?

I posted a few days ago about same question.But I can't understand well and I think it is not accurate about "polyfitc" when I used it.For example,RNodes(2.8667)>>>Aero Twst(13.308), RNodes(2.8667)>>>chord(3.532)I want to express such as upper.it means that they are related mutually.when I posted such as similiar question before, I got reommendation to use "polyfit" But it was not accurate compared to original values when I graphed.And I got another answer, but I coudln't understand well.so Could you help me again ?< I need to use original values without change a little>
