Hello, In the attached worksheet, the FFT of a function is calculated. I would like to get the amplitude at each of the frequencies from the signal. From the plots of the FFT magnitude at various frequencies, it can be seen that the peaks amplitude decrease with increasing the frequency. The plots also show that sometimes the first peak is larger than the second peak and sometimes it is reversed.   I was wondering if this is a natural behavior of FFT or I must modify the script. I greatly appreciate your advice.   All the best, Payman    

Hi I`m trying to make simple calculation but without success. What`s the problem? MC15 file is attached for convenience. Thanks in advance.

Hi I write a new calculus sheet, with it, i want to calculate a kinematic for parallel glide structure(  is it a Clavel's Delta robot variation)   In my sheet, i don't understand why prime don't solve the last equation see attached file Anyone can help me ?

I do not understand why I not get v_2 in mm and Ø_2 in rad?

I met something strange

I was just wondering if there are any free MathCAD software for student.  I saw there is a version where student have to buy it for $60 and valid for 1 year only.

I'm having a problem with Prime's assignment of labels, and I'm looking for a simple way to not fall into this hole again. Attached are Prime 6 worksheet and figure.

Hey, I have an assignment for school and the file is saved in old xmcd format from Mathcad15. Now I'm only able to work in Prime and I can't seem to be able to run Mathcad15 at my laptop so I either have to remake it all in Prime or have someone to convert it so if anyone would be so nice to do it I would be thankful.

Hi,I've a problem with the 'explicit'-command. The inserted values of the calculated equations are displayed as an unusual long number. I just want a number with max three decimal places after the comma.How can i fix this problem?Kind regardsMarco

The attached files have both been corrupted with following error code:   Does anyone have an idea, as to why this problem occurs? I am using MathCad Prime 5.0.0.0   Thanks for the help

I sewed myself an academic cap on the day of the number π with the number π raised on the facade. The cap area is minimal. The size of my head is 58 cm. The volume of the cap was equal to π liters. Tomorrow I'll go with this cap to celebration of π-number!

Hi.  I am doing a pretty simple calculation and I expect x = 3.3117 but 'solve' would not return the value.   I am inserting an additional line to calculate x manually in the middle of a design MathCad sheet but it is painful.   Why couldn't MathCad perform that simple numerical calculation but only repeat it symbolically?  Any help would be appreciated.

Hello, i have the latest Mathcad 15 that i came with Prime 6.  In the old Mathcad 15 I used to be able to do  "Control+shift+J" to create brackets around the variable.  I am having trouble with it with the new mathcad 15.   Is this feature still there? i assume it is. i noticed when i do it it launches another software called cisco Jabber.   Thanks, Sam 

Hello. How can I solve for c_1 og c_2 symbolic?  

i am working with fourier at the moment and when i assume n as integer is gives an error message, as seen in the photo linked   am i using this wrong or is it not able to apply to this. i know the answer is 2/(pi^2*n^2) but i would like to have mathcad solve it for me for other equations  

Hi All, I am very new in Mathcad, have a very basic question. consider the below equation: Mathcad solves the equation and finds the "v" as is expected. Now I add units to the equation:   I don't know why I don't get the same value here directly after "solve,v"? In the following, I can return the value of "v" and get the values which are correct.   Is there any way to skip the part shows first within the [ ] and get the final answer?     In addition, Is it possible to rewrite the equation symbolically and get an expression for "v":     another example for clarification: Thanks.  

I have been looking at some of your post and learned a lot. I am new to mathcad 15 and i have come across a problem with units. I have a program which gives me a matrix and that matrix has different units. how do i assign the different units within that program

I realize that there is a new advanced(?) plotting function in Prime but some of us are constrained to Express.   In Prime 6 Express, define TT as a range variable for plotting 120 deg F,119 deg F . . 103 deg F. Plot TT vs TT.  get Plot function against TT, get:

I would like to shift the values of the last part of a table. Is that possible?

What more constants will be good to have here?

Hi, I encountered an error when I tried to plot a graph including arguments (t and Δ(t)). The error says:This function has the form:f(f(Unitless)->Unitless)->Unitless, but must have the form:f(any1)->any2. I have attached the file. Can anyone help me out? Thanks a lot.

I queried Mathcad Prime 3.0 for the number of cubic inches in a gallon and got 231.  I wondered to myself if this was an exact conversion so I increased the displayed decimal points to 15 and realized it is not exact.  I did some internet research to find where this weird number came from and found that it should be exactly 231 in^3.  Is this a mistake in Mathcad or am I missing something?  

Hello everyone,   does anyone have an idea, how to push results calculated in CREO MDO to Mathcad, using the parameter transfer/engineering notebook functionality? I know, it is possible to transfer one value, but what, if the value change? E.g. an angle within a MDO Simulation or a resulatant force in a bearing in MDO. Best thing would be, to transfer the different results and name them as X1, X2, X3,... The workaround, to export the MDO results to Excel and import them into Mathcad is not the way I would like to use.   Thank you for any help. Axel

Hello,Is there any possibility to plot a diagram formed by vectors representing complex numbers? (see attached file).I want to visualize the vectors in this file (e.g. in cartesian coordinates). Notice that V1 = V2 + V3, that means all three vectors form a triangle; and I want to visualize this triangle.I have to tell Mathcad that vector V3 does not start from the origin of the cartesian coordinates, but instead starts from the end of vector V2. Same thing for V4, V5 and V6.Any help would be much appreciated.

Hi, I am looking for a solution to my question, "can the coefficients be evaluated/shown as numbers in an equation?"    example)   a:= 3     b:=3   c:=7   2a (x^2) + 3b (x) - (a+b+c) = 0     can the obove be shown as:  6(x^2) + 9x - 13 = 0
