Hello,I'm having a problem with defining parabola's function f(x) when a,b,c are unknown. I can solve a,b,c with given/find-procedure but I have no idea how could I make mathcad to give me the function included these now known a,b,c (something like: f(x) = 4x^2 +3x + 1)I attached my work so far so maybe it's easier for you to understand what I meant above.I would be very pleased if someone could help me out as soon as possible.Sincerely,Joni(btw I'm using mathcad 15)

不是因为没有开自动运算，但是就是不能自动运算，求助大家

I've buyed a single user verion of Mathcad Prime 3.1 with one year Support included. Maybe i will extend this contract until verion 4.0 is published. In the next three, four years it maybe that new hardware, especially a new pc will become required because the Hardware i'm using yet is five years old.Support contract.Must i have a support contract to change the host id of the license? If so, can i reactivate a support contract that has ended several years ago?Many thanks for any response.Best regards, J. Dessecker

Hi!Currently, I'm working in a people counting project.As a start, I want to make a program where given this image of a group of coins:one can authomaticaly count how many coins are there in the image.With some matrix manipulation, I've issolated the coin borders:And now I want to know if someone can help me in counting how many of these round blobs is there in my image. That is, the program that I want to create must tell me: "there is 10 objects in the image"Any ideas?thanks.

While trying to install Prime 3.1, the license pack generator asks to install Pro/ENGINEER Wildfire 3.0 or higher. What is this and is it necessary to use Prime 3.1?

Hello all,I need to plot 20 traces to really represent my data clearly.Is there a simple way to increase the number of traces you can have on a single plot beyond 16?

I use mathcad program.I want to have "sys_r" graph.I try a below captured programming.But programming error occurred.programming error!Error is "This array index is invalid for this array."I don't know solution.Please help me.graph shape example !

I want sys_r graph.a <- programming errori don't know errorI want solutiongraph shape example please........

I can find and replace 2 for example to space in Mathcad 15 (Ctrl+h) but cannot do it in Prime Is it a bug?

Dimensions of the selected copper trace are typed into Mathcad so that the propagation delay associated with a signal sent through the trace can be calculated. This will enable the Design Testers to verify the propagation delay is within the acceptable range as defined in the Design Requirements.

Dimensions of the selected copper trace are typed into Mathcad so that the impedance associated with a trace can be calculated.

Dimensions and geometry of the 2 selected copper traces are typed into Mathcad so that the cross talk associated with a signal sent through the traces can be calculated. This will enable the Design Testers to verify the cross talk is within the acceptable range as defined in the Design Requirements.

‌Does any one know how to access an upgrade download for Mathcad Prime 3.1? My subscription download portal is still showing only MC Prime 3.0. Is there some special things that I have to do to refresh the portal so that MC Prime 3.1 becomes available in the download list or is it only available to new customers?I would appreciate a response from anyone that has got thEire hands on the upgrade because PTC doesn't seem to care to respond In any way to my query. I suppose that happens when a company grow to big on the backs of their users to care.Regards, Mark

Hello,in attached mathcad 15 sheet, please scroll down to three red arrows(pg 4) where i tried to solve the equation in three different ways, but non worked. this problem can be thought of as an eigen value& eigen vector problem. i am trying to solve for the eigen vector corresponding to a certain frequency.Thank you!

Hi everyone,I need help for a really simple question, I bellieve, concerning the units in a spectrogram, that in turn comes from a fft function. I refer to the example to be found in QuickSheets "WAV-Files, Spectrograms and Signal Generation" (under Engineering Applications). Since I am not very confident with signal analysis, I have always problem to interpret the units in the frequency axis of an fft. In this example Quicksheet (also attached), the frequency axis is vertical as usual for spectrograms. But how can I know which frequency corresponds to the index of the plot?For example: here I have 256 samples and the rows of "spectra" are 129. How do I convert this 129 in Hz? Which frequencies dominate in the signal in the first two seconds?Here under I have now, as a test, only the half of the samples (128). The index is now 65. How do I convert this 65 in a frequency in Hz?I can see that there is a proportionality, and that it must depend on the sampling rate and maybe on the total

See the video: Video Link : 5835 An oscillating cylinder steam engine is a simple arrangement which does not require valves to direct steam into and out of the cylinder. Instead of valves, the entire cylinder rocks, or oscillates, such that one or more ports in the cylinder line up with corresponding ports in a fixed port face or in the pivot mounting (trunnion).See more here about this engine.

Hey there,I'm having hardship in finding any version of MATHCAD software that can run on 64-bit windows. Perhaps, I'm just from the old school and my expertise came through working with many engineering companies where MATHCAD was the tool number one for design, and therefore, I had to learn it.Now, I'm attending the graduate school and it looks none of my new classmates have heard of MATHCAD! The trend speaks MATLAB! The university is vehemently touting this software from MathWorks. They made MATLAB free, free online training, free tutorials, free on-campus training, free one-to-one training, free maintenance, and most importantly, MATLAB can be installed on any operating system from windows XP 32-bit to 8.1 64-bit and any of Mac IOS system!And guess what! MathWorks package offers us access to all of the following for free:MATLABSimulinkSymbolic Math ToolboxBioinformatics ToolboxControl System ToolboxCurve Fitting ToolboxData Acquisition ToolboxDSP System ToolboxImage Processing Toolb

Hello,i have three questions in the attached sheet about symbolic evaluation. please scroll down in my sheet until you see red arrow. i have a question next to each arrow.Thank you!
