Mathcad

Hi everyone,I am reconstructing, in a Mathcad 15 worksheet, the proof of a theorem but the result gives me the wrong sign. Can anyone tell me where the mistake is? See photos:

Mathcad Prime 6.0.0.0 "Help Center" available on the following link: http://support.ptc.com/help/mathcad/r6.0/en/

I'm trying to reproduce some of my Mathcad sheets in MS Excel format. One of the biggest hurdles is a finding a simple way to define a range (or column in the case of a spreadsheet) of dependent values that are defined by a start, interval, and end value similar to Mathcad's range variable. I'm guessing I'm going to need to implement VBA, but my skills with that are pretty minimal.    Does anybody have suggestions or examples?

Hello, I am trying to activate a copy of Mathcad Student I downloaded from the website. However, I cannot find where to apply for a License to obtain a product code and am therefore unable to activate the software.Can someone help me find my way around to get a License?

Hi, Could anyone tell me, why I'm getting just one solution when solving, when there are cleary two? I already tried "solve, fully" btw.    

Hi,   Is it possible to use the CWD variable to reference worksheets? Meaning instead of clicking on the 'Include <<' button and choosing the referenced worksheet file, to write something like: "CWD\Reference.mcdx" in the field next to the Include << button. I'm using Mathcad Prime 6.0.   Thanks in advance.  

Hello,I am using PTC Mathacad Prime 6.0 student version for my civil engeneering procjet but after while about 2-3 hours program starts to lagging. Even adding new variable takes few seconds. The file is not big 127 KB and has 23 pages. When I restart my laptop everything is ok for next 2-3 hours. Any sollution?

Hello, I am new to MathCAD and need some help writing a loop. I have done this in MATLAB before when I was in college, but it seems like MathCAD works a bit differently and I just can't figure it out.   I have two variables for which I am inputting to a starting value, say A:= 1.5 and Dp:=3. Then there are a few lines of equations that all use A and Dp, and eventually output a final value that I named Apercent. My goal is to have the program automatically increase the inputs A and Dp from their starting values until Apercent is at least 100.     My plan is to create a while loop that says "while Apercent is less than 100, A will increase by 1/16 at a time. But if I reach an iteration where increasing A no longer increases Apercent, stop increasing A and instead start increasing Dp by 1/16". But I can just not figure out how to write this in MathCAD. Can anyone please help me and show me the proper formatting?

HI   Is there a way to get the Prime Variable identifier on top of the column like we can get in Mathcad 15??   Thanks.  

Hi ALL, To whom of interest: analysis of a linear time-invariant electric network, with the incidence matrix method. However, something is not correct for me, see last photo (there is the sum of an integer number and an inductive admittance, that is the dimensions of both terms aren't the same). Where is the mistake?.

Hello everyone,why the program, reported below, does not work? There seem to be problems with conditional operators. In fact the program on the right, where no conditional operators appear, gives the required result.I sincerely thank those who will find the error and all those who will try to solve it. Attached is the worksheet.

  Is it too big??? is there any way to figure this value out ?

I want to remove mathcad from my old computer to install it on a new one. How can I do that.    Thanks

Trying to finish solving this problem but keep running into an error. Error message is "This value must be an integer" Mathcad file is attached. 

  How can one re-write the equation with only theta on the left. I need to calculate theta when Q is known. Will this be possible? Q is a ratio variable that rages between 0 and 1 and will be known from previous calculations. I know when Q=0.5 the Theta = PI and when Q=1 then Theta = 2*PI

Too many initial conditions error in Mathcad using Odesolve. Need help in order to finish lab. attached is lab. 

Hi all,   I am working on a problem for my class and I'm having trouble even beginning to program this transient heat conduction problem.   I have attached a sheet with information regarding the problem I am trying to solve. What I want to do is eventually increase the order of my interpolation functions (from linear to quadratic and so on) and also increase the number of elements I use and compare how well each of these methods converge, but I don't know how to incorporate iterating through time into my dependent variable while still keeping it a 2x1 vector.   Basically, I have a boundary condition at u1 for all timesteps and and an initial condition at t=0 for all x, but short of adding another index onto my u vector, I don't know how to actually iterate through a number-of-timesteps value. I don't think I can add another index onto the u vector because then that would change the outcome when I multiply my matrices by that vector.   The difference scheme I want to

Hello, Sir My costumer have the problem of the mathcad, and I don't know how to solve it. Is there

There are nine definitions of a circle. Is this the tenth definition?

Good evening to all of the community,I have this little problem (see photo) that I can't solve ... in fact I want the "Case 2" to work too. How to do?  

I need a "forcing function" that will be continuous (not piece wise). It needs to be a rectangular function with amplitude "A", Period "P", and duty cycle "D" (40%) that is a function of y(t) for some time period "t".   Can anyone help me out with this?    Thanks, Mike  

My mathcad worksheet performs various calculations and references another mathcad worksheet that contains various fluid properties. I have several worksheets of properties each for a different fluids and I would like to be able to easily switch which file is being referenced depending on which fluid I am interested in without having to delete the reference and insert a new one.     In my main worksheet with all of the calculations I would like a variable that tells the rest of the worksheet which file to reference.        Fluid = "Fluid 1" Calculations use properties of "Fluid 1" 

please help me   why it says this variable is undefined

d2 has to be blow 0.3    but the answer is 0.3   please help me..

  X=0.5*exp{(0.3+2t*x0.1)*t}-0.5*exp{(0.2+0.1*x0.8)*t}     I need to solve it in t=0.1,t=0.5,t=5   But I am having problem in math cad...
