Hi,This is a copy of my worksheet, as said in my previous post I want to vary the angle to get 10 different force outputs for all three. I am struggling with the "find" commmand.Any help greatly appreciated, thankyou!cameron
Hi,I have three equations which I want to solve. The equations are made up of variables which change according to a specific angle which updates them. I want to get the results as a vector which shows how they change according the angle which is changing the input values. Basically I want to input 10 values and get 10 answers out. But the "find" command that I am using just isnt accepting it. It only accepts one input and gives me the output, I must then go change the input to get the next output; but I want a nice set of vectors to do this in one step.Im not sure if I explained that the best but if anyone could tell me if the find command is capable of such a thing or if theres another way to get around it..such as a loop or something.Any help would be greatly appreciated, thanyou!Cameron

Hello everyone! I have some problem in cycle that I made in mathcd 15. I wrote short code to calculate pi number but only 14 numbers after point I can only see in my array and dont know what to do. Can anyone can help to solve this problem? @

Internal Creo Software Versions don't line up (WF 5 = 28 but Creo 3 = 34). Main place you will see the versions appear is in license files.Creo 1.0 = 32?Creo 2.0 = 33?According to my math, there are three version numbers that must have been skipped along the way.
I have tried to solve differential equations describing the bending behavior of a beam. The equation is:EI * w'''''= -qThis is only valid when all the derivatives of w are continuous.Thus in the case of a point load, a new section is to be defined and conditions are formulated.(same deflection, same angle, moment equilibrium, shear force equilibrium)What is going wrong in my file?
We have a user that is receiving an error when trying to save files as PDF."Windows cannot find 'C:\Program Files (x86)\PTC\Mathcad PDSi\Acrobat\AcroTray.exe'.When browsing to the directory listed, the "Mathcad PDSi" folder and subfolders do not exist.We've tried searching high and low for an installer for Mathcad PDSi, but can only come up with "should we uninstall this" guides.Any help finding the installer for this PDSi program/addon is appreciated.
Hey,When I tried to solve a second order differential equation with odesolve I get the above mentioned error. First order ode's work fine.

Hey guys,I'm Laura and im currently working on a worksheet in mathcad Prime 3. The first time programming and having a hard time trying to compute a rather simple loop for an explicit time-stepping (numerical evaluation) problem. For those who are familiar, it's the book of Chopra-Dynamics of structures ->chapter 5, p. 207, Central Difference MethodIf someone could help me out, tips making the program work, that would be greatly appreciated!Laura
Elllipse: yes - three l in the word! The ellipse with 3 focuses! Author - Werner Exinger (view in My Videos)
The paper ‘Modelling the transient emission from a twin-conductor cable’ describes a test where a step pulse is applied to one end of an open-circuit cable. - http://ietdl.org/t/ZKt6U The waveform of the differential-mode current delivered to the line was recorded. This was different from the waveform of a lossless line, since there were radiation losses. A circuit model was created to simulate the hardware-under-review and was subjected to transient analysis. Adjusting component values of the model enabled close correlation to be achieved between test results and model simulation. The process of creating the model provides an improved understanding of the mechanisms involved.The ‘References’ section of the paper includes a link to the Mathcad worksheet which performs the calculations. Comments will be welcome.

Hello everyone,Does anybody know, if PTC developed the secondary axis function already - for Mathcad Prime? The old Mathcad version had this option.It is horrible without it, for example in case of a Bode plot. I would like to see phase shift and gain on the same graph.Any hints?Or any alternative solutions for the problem?Thanks!
My installation of Mathcad Prime 3.0 on Windows 7 just started printing blank pages whenever I try to print a document. I printed several documents just a month or so ago with no problem. It doesn't matter what printer I use or if I print to PDF; I get the same result. I'm wondering if there was some update to Windows 7 that clobbered Prime's ability to print. Mathcad 15.0 M045 is printing just fine. I even re-installed Prime 3.0 and it didn't fix the problem. Any thoughts would be appreciated. Thanks!
