Hi,Why is it written that for subscript in text one needs to press ctrl+- and for superscript in text one needs to press ctrl++, while if someone press ctrl+- and ctrl++ it comes out of the way of being able to use subscript and superscript in the text. Is this indication written wrongly?  

Given an ellipse E in the Cartesian coordinate system with the semi-axes a > b and the equationx^2/a^2 + y^2/b^2 = 1. A chord AB of fixed length s < 2*b is considered. Let the point P be fixed on the chord so that the chord is divided into the segments AP = u and PB = v, i.e. u + v = s. The points A and B should now be moved on the periphery of the ellipse in a rotational direction while maintaining the chord length s and its pitch P in u and v. During this movement, point P describes a closed curve K.The content of the annular area bounded by E and K is sought.

Why is the PTC process so convoluted?😫😫  This is the reason I never use PRIME and stick with MATHCAD 15.  I am one of the respondents totally disgusted with PTC as noted on this forum thread.https://community.ptc.com/t5/Mathcad-Installation/MathCad-15-permanent-Product-Codes-no-longer-verified-by-PTC/td-p/815892 In order to help a friend decide on PRIME, I downloaded MATHCAD EXPRESS,  actually PRIME 10 30 day trial.  It supposedly installed because there is a PRIME 10 exe file.  I downloaded the license from my email.  When I try to run MATHCAD PRIME 10 for the 30 day trial nothing happens when I click on the MathcadPrime.exe file in the PRIME 10 folder in Program files.  It never asks for a license; it never installed a desktop icon.  It never showed up in my Start Menu.  Their so called instruction guide is pages long with no succinct summary.  I don't have time to study a lengthy installation guide for such a convoluted p

I was writing up the one of the Mathcad examples for CHAPTER 8: Earth Retaining Structures8.2 Reinforced Concrete Retaining Walls with Sloping Backhill. Could you please help me finding why the error massage was showing up?

  Can you please help me solve this issue? I don't see any faults on equation. Please let me know if I am overlooking at something. Thank you. 

Hello, Please let me know if PTC still officially supports Mathcad Prime 7. Is there any official PTC link where it is stated that this version of the Mathcad Prime software is officially supported? Warm RegardsVijay

Hi,I am making something wrong? Are only 3 differential equations... But using laplace command this system of differential eq can be solved:   See MCP9 file attached.

Good morning,I would like to convert xmcd files to mcdx format.I have Mathcad 15 software and a trial version of Mathcad Prime.The conversion is refused, probably because Mathcad Prime is a trial version.Could anyone convert them for me? I have about 15 files.Thanks in advanceRichard

How I can  tell matcade when the angle is divided by zero consider the value to be zero   

I'm trying to calculate the distance when I do it manually I get different results from the one mathcad givesLp1 should be the same of LP1I also need to write a program to make this function uses different fixed point , for example the first time it will use X1,Y1 (0,0) as fixed point and I get the values for Lp1 the second time it uses x2,y2(2,0) as fixed point and I get the values for Lp2 and repeat the process with the all points to get lp3, lp4 ... and so on

Hi,For below circuit:1. Find the expression of the voltage across C2 (Vb) at t>02. Find the voltage across C2 at t=100ns when C1=100nF3. Find the voltage across C2 at t=100ns when C1=10nFAlso let C1 and C2 voltage  as t-> infinity to be Vb.    

Hello Experts, Please help me with the Subject issue, "How to extract the several Sol Data to one Excel sheet through "WRITEEXCEL" function?" In order to reduce repeated works as I should handle many cases, I want to extract several Sol Data into one Excel Sheet file but no idea :(( Please check the attached mcdx file for the following questions.1. How to get all of the data values(Sol, Fy, y, y1, Fx) highlighted with yellow color in one sheet of Excel file by using "WRITEEXCEL" fucntion? 2. The value of Fx is same for all the variables of each matrix row which shouldn't be correct. Is there any mistake for that? Please give me any advice or solution. will be much appreciated. 

Why can't I get a 30-day trial? The previous owner used up his test period. I am a new owner of a laptop and by entering new data I cannot obtain a new trial period on this laptop. What to do?   Translated by the Community Moderation using Google Translate ----------------------------------------------------------------------------------------------- Dlaczego nie mogę uzyskać 30dniowego okresu próbnego? Poprzedni właściciel wykorzystał swój okres testowy. Jestem nowym właścicielem laptopa i wpisując nowe dane nie mogę uzyskać na tym laptopie nowego okresu próbnego. Co zrobić?

Good afternoon,I'm sure someone on here can assist, we are fairly new to using Mathcad and we are struggling to get the lambda formula in the below snip into a Mathcad sheet, it throws up a number of errors and we aren't sure what numbers we should be adding where.  If anyone can assist, we would be very grateful.CheersSimon  

I have an already filled in Excel sheet with parameters and variables that I use in a Mathcad calculation. I could copy 'n paste the content to an embedded Excel component, but I'd like to avoid such menial task. Has anybody figured out whether and how to insert an Excel component that has content?

Hello guys,I need some help.I am trying to solve the following problema.But it seems I'm stuck on the binary variable and this causes errors in the constraints.Can anyone help me out of this jam?CarlosRomero

In Mathcad 4.0 it is not possible to show date in ISO 8601 format (YYYY-MM-DD), e.g. in the page header.As this is the format we are using in our office, I'd like to add that as a choice.

Hey, I have problem with system of differential non linear equation. I dont have any idea how to solve this. I hope you will help me 🙂 

Mathcad Prime 9.0.0.0I'm doing a separation of variables equation, where I start with the equation at the top left in the screenshot. Using the solution that mathcad provides from the integrals, i get an output, that doesn't match up with the true answer (highlighted in blue). Am I using it wrong?

Hello,I want to extract for each iteration o i, the corresponding value in 20log() vector at index i, and put that value into another vector.     And so on..

I  want the values of qcsand to be only between 5 and 25 I how to fix that 

Hello,These examples are for each particular i:   But how to iterate through all values of i:

Both of the variables have the same unit, however mathcad said units are not compatible why is that?

I truely don't know why this error keeps happening?!
