Mathcad

Fred sent me his file.I posted about integration. so He sent a file about Tutorial on range variables, vectors, and functions.I am trying to do my work with his method.But I had a problem. it is how I can read my data(CL, CD) along "angle of attack" I couldn't read data by using his method.so I want your professionals to get advice.I can't pass this procedure.last one of attached file is file that he sent me

Hello everyone. Need help defining variables. I would like to define a variable as h/tw:=49. however everytime Math CAD recognizes / as he division operation and I am not able to define my variable. Is there and way to accomplish this?

Hello,In the attached sheet, please scroll down to the red arrow. is there a way you can display the index value for "W". Thanks!

Hi,I'm starting to use prime 3, mainly becuse I manipulate large files ( typically 100X100 arrays of nested 5000 elements vectors) and even using function for most of calculation Mathcad 15 ran quickly out of memory.No memory issue with prime but instead an incredible slowness in reading/writing files ( prn), a lot of pause in editing even if computing stopped . Also there is no autosave, and often crashes ( not responding) without any way to leverage Escape key.Issue are happening even if if memory and CPU is far from saturation.Combined with mediocre ergonomy on menu, por productivity overall..am i missing something be ( I admit I did not read help documents fully)Thanks for suggestion...JFG

Hallo,ich nutze MathCad Prime 3.0 und habe folgendes Problem:Ich definiere eine Variable und gebe ihr den Wert 1.1. Lasse ich mir nun die Variable ausgeben wird der Wert 1 angezeigt (bei eingestellter Anzeige von Nachkommastellen!). Auch bei Berechnungen (bspw. 0.5*Variable) kann er die 0.5 nicht verwerten und gibt 0 als Lösung aus. Tippe ich die Gleichung im folgenden Format ein ( (1/2)*Variable ) funktioniert die Berechnung problemlos.Bitte um Hilfe, ich komm mit dem Problem einfach nicht weiter. Danke und Gruß, Chris

Hallo,wie kann ich die Schriftart für Texte von Tahoma nach Arial oder ähnlich pauschal ändern ?Wie stelle ich die Schriften für Variable und Einheiten um ?Bei mir werden unter Windows 8.1 die Zeichen beim Druck nach PDF unleserlich. Zum Drucker geht es.Danke für jeden Hinweis, Gerd-Wilhelm

hiGood day. I have 3 vectors, say L1, L2, L3. And now I want to get results for cross products of all possible combinations with two vectors (which is acctully L1xL2, L2xL3, L3xL1). How can I get it with programming or in a easy way avoiding making three formula seperately for three results. Is there any function which can do this circular loop or other easy ways.Best RegardsJahangir

Hello,Not sure why Mathcad is not doing a surface plot for this function in the attached sheet. Thanks!

I am sure that this question has been asked before but I have developed a program in MathCad Prime 3 that I would like to turn over to a programmer who works in MatcCad 15. The current plan is that he is going to add increased functionality to the program.I know that MathCad Prime 3 can upload MathCad 15 files but can MathCad Prime 3 files be converted back to MathCad 15 format?

I had been running Mathcad 11 on a XP machine. I would like to run it on a new laptop with a 64 bit windows 7 system. I tried various compatability modes with no success. The program seems to install but will not run. Is there a way to do this?

Will Mathcad 11 work with Windows 7?

Hello,Could you please help me with the attached graph? The surface graph shows much higher values for the parameter on z-axis.Thank you.

Hello there,Listen, I'm try to use a 3D function to describe a path of an ant in a surface.The surface rotate at 2*pi/ sec and the ant walks in line from center to away 1 cm/s. The surface is a circle with 1m radius.After all parametrizations, i have problem to draw it. (you can see document attached)This is the function that indicates the position of the ant dependent on time:Then I CreateMesh and this came:From 0 to 50, it should draw a spiral with 50 lines, or I'm I wrong? And how can i chose Step size in CreateMesh?I want like t:=0, 1, 2, 3 .. 100. How can i do that on CreateMesh?Regards,L. L.

Hi I am fairly new to mathcad and I'm having a problem creating a graph of an equation, which describes the transient behaviour of the torque generated by a moter during a fault condition. The datasheet where the equation comes from states that the maximum value (-295.4) occurs at t=0.016s and so I have been able to check that the equation is giving the correct answer for a single value of t.I now want to create a graph of the function, but when I try to do so, I get an error stating "Plotting failed. Replace complex values and NaNs by real numbers".Can anyone tell me why this is going wrong? I have tried it with and without units; using t and t1 as the argument.ThanksKenMy Mathcad Prime 3 worksheet is attached.

I am new to mathcad and I am just starting to play with simple problems first to learn the necessary interactions with the program to achieve desired goals. I am working on a very simple problem that starts as seen below. Life_Expectancy:=10yrCyclesPerYear:=21900cycles Total_Cycles:=Life_Expectancy*CyclesPerYear= With this mathcad can not compute the Total Cycles and does not display cycles as a unit. I have highlighted cycles and changed it to units to no avail. I have also tried changing the term cycles to wipes and iteration but neither worked. What am I missing to make this simple problem work? Thank you

And secons.I see C, R and Z in help but C, R,Z and Q in the list of symbols.

Hi,I was wondering if there was any way to use find given a set of differential equation. Here is a (simple) example : charge of an RC system.input voltage, and capacitor value are known. I want to find the resistor value such that, after a given time Tx, the capacitor voltage is Vx.Obviously, this example is simple enough to solve manually, but could this be applied to much more complex systems where manual solving is not an option.

hi,i would know the difference between mathcad 15 and mathcad prime 3.0.which version should i get?thanks

I'm having an issue with the "Readexcel" command in Mathcad Prime 3.0. I have an Excel spreadsheet that contains several cells of data that I'm importing into my Mathcad worksheet. My problem is that once Mathcad reads the Excel file I can't enter a new value in the Excel sheet and get Mathcad to import it without deleting the existing readexcel input and reentering it. I've tried closing and reopening the document to no avail. Is there a way to get Mathcad to reevaluate the input without deleting it and starting over?The cells I'm reading are part of a larger Excel worksheet and it would be easier to leave it as it's own worksheet rather than an embedded object in Mathcad. Thanks in advance.

Using Mathcad Prime 3.0 is it possible to chanee the background color to white?Mostly I take screen captures of my equations to paste into word, since the Mathcad page color is not really white I have to go through paint to get it right.If its not a feature any chance something simple like this can get into a future release.

I would like to show my students a symbol math in Mathcad and in Internet. But:

I saw prime 3.0 book and then I got some questionIn this picture, T has three "variables". it is mean " i , j , k "I tried to calculate differential about " r " but I got error.So I want to calculate in "solve block" But I am worried that I saw that "solve block" can calculate only "one variable"IS is right?and Now t has variables " i, j, k"" r " include " i " . so when " i " change, " r " is also changed.so the thing that I want to say is possible to get values about " r " when I calculate differential about " i "

I tried to know by searching "google" and "PTC site".But I don't know well. Just, I saw two posting. one is said that "vector" couldn't integrate the other is said that "vector is possible to integrate"so I felt confused..I need help.

<I hope to know. I spent time to know this method for 2 days >I was going to convert "range variable" to "vector"I finally finish to change.After that, I tried to integrate, but I couldn't do it.I could integrate before changing "range varable" to "vector"so I guess that the problem is due to "vector".could you give me advice? I attach my file. thank you for reading my question
