Mathcad

I have about 200 Mathcad files / All of a sudden they all disappear. I did not delete them, where can they go?? how can I recover them?

How do I enter this differential equation into Mathcad 15, and make it find the symbolic result?f'(x)=1+f(x)solve for f(x)( where f'(x) is the derivative of f(x) )I know the answer isf(x) =  e^x - 1Thanks

Can you find with Mathcat the optimal value of L

Hi ALL,Why, in the following immage, the latter two modules, highlighted with purple frame, are partially simplified? ThanksF.M.

   Dear all, recently I reinstalled Mathcad Prime 3.0 and now it gives an error with the words "Unknown errorCould not initialize outfproc symbolic engine "in any calculations.  What should I do?

I'm trying to define a function with a Given/Find solve block inside. i.e. the function calls a Given/Find block.   I found this thread on how to do it Embedding Solve block in a function - PTC Community It had an example file: https://www.ptcusercommunity.com/servlet/JiveServlet/download/30310-2824/collab%20-%20solve%20block%20demo%2001.mcd   The problem I run into is that the values I pass into the function (which is used by the Find block), is ignored. Well, not exactly ignored - I think it uses it like a guess value. It solves the system of equations, but the parameters I passed in are changed.   My file is attached. TIA,Jason

I’m having trouble solving this system of differential equations. I’m pretty new to Mathcad and I don’t really have that much experience with differential equations either so I’m really off to a great start. I’m trying to calculate the flight path of a spinning tennis ball being launched at 45 deg. I am working with some numbers now but they are partially placeholders. I removed units for now just to take out one level of complexity. Feel free to check my equations but the real problem I’m having is with my initial conditions (I think). I keep getting the error message “Unknown error: dae%_­inital%­_condition%_error.” and I'm not sure how to fix it.I’ve attached the file below. I'm using Mathcad prime 3.1Thanks

Hi allIn Mathcad Prime 3.1 has come out this inexplicable error. How to correct it? it is enclosed in the box in black, of the following figure.Thk.

The original Mathsoft/Mathcad patents for the live maths whiteboard were many years ago. Those patents prevented the likes of Maple and Mathematica producing similar 'live math white board' products, and they were all stuck with having to do the 'FORmula TRANslation' approach of the text expression with after the fact symbolic displays.Looking at (US/WTO) papetnt lifes it looks like the lifetime of those patents was 20 years http://patents.stackexchange.com/questions/312/how-long-are-patents-valid, so anything before Jan 1996 should have lapsed. Mathcad - Wikipedia, the free encyclopedia shows that the original mathcad was released in '86, and by '96 Mathsoft was already up to V6.0 plus, so most of the key innovative aspects wre already there (some still swear by V6!).There have been more recent changes such as the text entry change, but that isn't part of the basic 'white board'.Is it likely that there will be other live maths whiteboard providers any time soon, especially extensible

  Hello, Everyone. From :    Is there a symbolic :,f(x),solve, symbolic ==> real number ?         Thanks in advance.               Regards.

Hi I am trying to install Mathcad prime 3.1 on windows 10, now I decided to clean my PC and do a reset as I had a load of apps I wasn't using anymore. When I tried to install Mathcad prime back on it keeps failing. I get a strange 101% installation notification bar in red and that the application has failed due to some VC80 issue. Anyone else had this problem.

Bonjour,Using two type of presentations for the calculus of a classic integral , I don't have the same result.See the joint MCD document.Thank you for your help and Best regardsClaudealibertc@wanadoo.fr

Hi All,I am trying to evaluate the deflection of a simply supported beam (which is subjected to 3 nos. of trapezoidal loads with different start and end ordinates and start and end points on the span of the beam). I tried to formulate the calculation using programming options of the Mathcad. Somehow I ran into a mistake and I could not able to trace the mistake. Can someone please help in finding the mistake.For a clear picture of the problem, please refer to the attached snapshot.Also, the value of deflection at the supports of the simply supported beam shall always be zero irrespective of the loading condition but in my case, the deflections at the support locations are very close to zero but not zero (snapshot is attached for the same).

Hey,i would need a short another help of you.This is a par tof my Calculation:Now my question is,how is it correct to write the fomulas with that variable?I dont get rid of this.Thx !

I have encountered what appears to be a problem with a Boolean operator I am using in a short routine.  I have attached a pdf of the routine for anyone interested.  The values for "TestLeft" and "TestRightIncorrect" should both be 3; however, the "TestRightIncorrect" value is 6.  I have included a modified routine called "TestRightCorrect" that gives me the correct answer, but I do not think this modification should be required.Any advice or guidance on this issue would be greatly appreciated!Thanks!Steve

I can drop the firewall to get MathCAD license, but that is not acceptable.  I've tried creating Inbound and Outbound rules that open 7788,27000-27010.  That doesn't seem to work. MathCAD 15.

Hi, how can I solve a system of ordinary differential equation (with relative boundary condition) in mathcad 15?I must determined an elastic linear equation for a beam fixed to an extremity and with to transverse force applied in different point.Best regards

I am discovering that in Prime 3.1 there is not the possibility to manage ( or at least I have not been able ) East and North geographical coordinatesexample : East01 = 12° 20' 30" , North01 = 44° 14' 28"I found only the measure unit of " ° " but not first ' and second "I would like work with the above mentioned coordinates and write some programs to convert them ( for example in grade sessadecimal ) or use to determine direction ( from East01,North01 to East02,North02 ) ; this second case is very frequent for the calculation of the navigation routesI am waiting to know the state of the art on this matter ; possible or not with Mathcad Prime 3.1 ; a few years ago , can not remember if with Mathcad 2001 or Mathcad 12, I prepared some useful routines for conversion and geographic coordinate calculations ; shame that they were lost two years ago with the breakup of my notebookNow I just have to look for (and hope to find) some paper copies of those programsthanks in advance to anyone wil

I find myself constantly using a system of 5 equations with 7 different variables. I always know two of the variables, but the two that I know changes. Is there a way to write a single calculator that can solve for the unknowns instead of writing a different calculator for each combination?equations:mt=mf+mwc=mf/mtvf=mf/8.34vw=mw/8.34vt=vf+vwUsing the solve function only lets me solve for unknowns, so I'd have to rewrite the unknowns each time.Using the find function requires me to guess, but I don't know how to distinguish from a known and a guess.I could use if statements, but I'd have to write a huge set of formulas, which isn't ideal.Any help would be appreciated.

  Hello, Everyone.From :The question : What does _n mean ?     Thanks in advance for your time and help.           Best Regards.

Hello everyone!I'm a new user of Mathcad and I encountered some difficulties. I need to write a mathcad script which would allow me to calculate output parameters of air in Earth-To-Air Heat Exchanger (temperature, relative humidity and humidity ratio).I think that the code is OK but Mathcad is showing me an error as I said in title. Could anybody help me with this? Best regards,Filip
