To alltrying to remember my school days and the use of derivative (if that's the tool to use). Given the followingan X,Y,Z Cartesian co-ordinate systema vector v with components (vx, vy, vz)a rotation matrix around x-axis Rx(theta)Header 1Header 2Header 31000cos(theta)-sin(theta)0sin(theta)cos(theta)Is there a way of finding at which angle theta the z component is the highest?ThanksRegardsJXB

Hi, Can anyone out there help?  I have a fairly basic calculation sheet, in which I want to use results from another worksheet.  I have done the insert reference, saved, saved again, hit F9, hit it again, opened, closed, re-opened, re-closed etc, but simply cannot get the recipient worksheet to find the array results that are generated in the referenced sheet.  It will happily find 'simpler' results (single numbers, single column arrays), but will not find the larger 2 dimension arrays.  The arrays I admit are large, 130 x 500, but that is what we use expensive software for isn't it?

HiI'm working on a sheet which has a number of solver blocks. For clarity of work and for a concise summary, I want to pull the answers from the 'FIND' function out of the solver block. Currently I have to do this manually as I can't find a way of automatically outputting the values into the main body of the sheet. Does anybody know how to achieve this automatically?Thanks

Hi Friends,Does anyone know how to solve a partial differential equation incylindrical coordinates?Please help me,Thanks for answering.

Hey so I posted some time a go and i got help really nicely. THX for that. I am working on a simulation but I cannot get it to work because of the error (this array index invalid for this array.) I dont know how to fix it can someone help me?THX.

In attached there is a system of two nonlinear equations. Graph indicates there are two solutions but Find only finds one of them.Is there a best practice procedure for searching for other solutions? Maybe by creating a simple program to loop over the x domain (valid values of x) or what do you recommend?Kind regards,Michael

Hello everbody,I have a set of file I am trying to open with Mathcad 15 M030.Some files are opened succesfully while I recieve the abovementioned error for others.I find it really strange and wonder if anyone else have encountered similar problem before or if someone can suggest a soultion to this problem.Thanks in advance!/Hassan

Hi everybody,I am using Mathcad Prime 3.0 and I am trying to plot a bode diagram of a transfer function of a transimpedance amplifer. Moreover, I would like to display the gain of the transfer function in dB. However, when I try to calculate the gain in dB Mathcad is giving me an error saying "units do not match". As an attachment you can find my worksheet. Does anybody know the reason?

To all I am looking for the mathcad syntax to carry out the rotation of multiple vectors through a range of angle (from 0deg to 90 deg).I have a number of vectors containing 3 values (Nx,Ny,Nz) given in a reference co-ordinate system (fixed) (subscript ac)A local co-ordinate system (subscript ‘) is definedI am attempting to write the operation of rotating the local co-ordinate by angle theta (around Xac axis) to get the new vector values (in thelocal co-ordinate) - for each vector and through the whole range of angle.I am struggling a bit with the syntax required and any help would be appreciated. Attached a mcad sheet Thanks in advanceRegardsJXB

How can I edit the axis of an XY plot so that my Y-axis goes in descending order (not negative values)? In Mathcad 15 I would just enter the numbers/range in which I wanted my axis to be and the function would move accordingly. In Mathcad Prime I don't seem to be able to do much editing.

Siden jeg fik installeret Windows 8.1 på min pc, har det ikke længere været muligt at lave en 3D graf af f(x,y) i MathCad 14. Er der nogle, som ved, hvad man kan gøre ved det?Før jeg fik installeret Windows 8.1 klikkede jeg bare på overflade-ikonet i Graf-paletten. Når jeg gør det nu, så kommer der bare en "sort lakrids" - altså en pladsholder for ét tegn! Det sker også, hvis jeg trykker på det ikon, som viser et xyz-koordinatsystem.Desværre supporterer Windows Update ikke MathCad, så de har ingen bud.mvhHelle

A question was raised if the capacity of an existing pneumatic conveying system, conveying HDPE particles, can be increased from 20000lbm/hr to 30000lbm/hr ?.This worksheet shows the calculations with unit conversions used in the system evaluation. Summary of calculations results are given with the references.

I am looking for steam tables for Mathcad 15. Seems ancient versions had add-ins but I find nothing these days posted anywhere.

Hi all!When i copy from mathcad and paste to word (i tried different paste options) text is ok, but formulas are as pictures, it is also if i save as .rtf file. Is there any way to export formulas to word as text or equations, and not as pictures?Thank you.

I have two arrays I want to use with a find function. I'm having difficulty getting it to work. Any easy advice? See the clip of the spreadsheet below. The arrays are "t" for plate thickness and "a" for the plate radius. As you can see the definition is just passing through the find function. This is a Roarks workbook copied and pasted into a spreadsheet - Table 24A case 3. Thanks for any assistance. This is M'cad 15.

Hello,I am using the ODESOLVE to simulate an RLC circuit. My states are my inductor current IL and capacitor voltage VC.I setup equations to solve for d(IL)/dt, and d(VC)/dt, and used ODESOLVE to get the values. I now need access to the original differential variables....I need access to d(IL)/dt to get my inductor current. Any ideas on how to? In MATLAB I could setup a global variable, but I am unable to define variables that use my states in the solver block.Screenshot of odesolver attached, I need access to IL(t)'

Dear Friends, I need to make a hydraulic profile of a channel. In which a control section is a free fall downstream of it. Use the software to little more than two months and do not have much skill with it. I'm trying to resolve the EDO (dx / dy = (IJ) / (1-Fr²), but I am not succeeding because an error appears in which I do not know identify. Attached hereto the file to anyone who can help me. Thanks in advance!Anderson Farias

Hola, soy estudiante y necesito ayuda para instalar Mathcad 15 en windows 8, gracias.

Dear All,I want to make a contour plot from a Matrix 2D which I can do, but the axes X and Y are labeled as 1, 2, 3, and so on. How can I change it to represent the real values?Just to clear the question. The matrix is the result of a Heat transfer analysis on which each cell represent an (x,y) position with the value representing the temperature on that position.All the best

Did PTC decide that Mathcad 11 single user edition is not going to be registered online anymore?Does PTC indicate that Mathcad 11 is not a valid product, or are they saying that they do not offering anymore technical support but Mathcad 11 can be loaded on a computer and then activated?Paul Unmack, PE- ME, CSE

Hello,I have two one dimensional matrix An & Bnn= No of column of the MatrixPlease see the attachment, which is quite easy to understand what I want to achieveThanks PS I am using Math CAD 14

I opened your attached file and this is what appeared (with a warning)  Hope this helps.

Hi,I'm IT engineer from DNVGL China.Our company bought and released Mathcad Prime 3.0 to all dedicated users for about 1 year.In the couple of weeks, we received an internet support request from one Mathcad Prime 3.0 user in DNVGL China office, that in his computer, when launching Prime 3.0, it will take a very long time to wait for the launch the application.The startup application window will get hang - "Not Responding", clicking it or not.User will have to wait for more than 40 minutes and finally it will work as normal - sometimes it just keep as "not responding" until terminating the process in task manager list.I tested it in my PC and got the same issue.I've read many articles and tried all those suggestions, including completely re-installation of this application as well as its dependencies, however none of them works.During the testing, I noticed the followings:When the PC is online (meaning has network connection), this issue will happen.When the PC is offline (meaning has n
