We have a paper blank square with sides of length A, from which we need to make a box. The box is made so: we got out of the corners of the small squares and fold the edges up - see the animation. The question is, what should be equal lengths of the sides cut out the squares where the volume of the box would be maximum?Мы имеем квадратную бумажную заготовку со стороной длинной A, из которой нам нужно сделать коробку. Коробка делается так: мы вылезаем по углам небольшие квадраты и загибаем края вверх. Спрашивается, чему должны быть равны длины сторон вырезаемых квадратов, при которых объем коробки будет максимален? Video Link : 6553 One solution

Hello,I am just wondering how to plot the direction field of an ODE.I saw a post where this was solved,but the worksheet was in Mathcad 14/15 and the converter fails, so I couldn't see how they did it.Thanks!

I've been reading through the forums but I have not found a solution to what I'm looking for. Basically, I need MathCAD 14 to read an Excel database are spit out specific values to be used in calculations.The excel file is a list of alum. extrusions and their section properties. Below is what I want to do.Die: 123 <--- This would be the input, the die that I want the properties for to use in the calculation.I=x.xxx S=x.xxx        These are the specific properties that would be auto populated based on the excel file.J=x.xxxand so on.I can then use those values in different equations throughout the MathCAD sheet.The excel file would be arranged with the Die number in column A and the output values in columns B to G (or however many property values that I would need)Hopefully I described it well enough that someone can point me in the right direction.

Hi All, I have a question regarding symbolic solution of three equations. Would someone look at my attachment and advise me how to do it? Thank you so much!

Will PTC release a mac compatible version of mathcad prime?

I have tried to create a surface plot where I fractional increments but have not managed to do this and can't find my error

Hello,I would like to import an entire worksheet from MAPLE or MATLAB. Is it possible? How should I do that?Also, I would like to export the code for those software as well.Thank you!

Dear all,I attach here a numerically-solved equation code for you. The tuning parameter in the code is alpha (alpha:=2.4/1.764). What I usually did for my work is to choose different alpha values and to generate the data of gdc vs. t/t_1618. I compare the generated curve to my experimental data and I justify the correct alpha values by naked eyes. Is it possible to modify my code to import the experimental data and let the Mathcad find the alpha value from a least-square fitting? I really have no idea how I should do that. Could anyone give me some help please?With best regards,Chien-Lung Huang

I am looking for a formula to calculate the voltage attenuation on a d.c. conductor (anode) in the soil. The anode is laid out in lengths of up to 500m and the requirement is to calculate how often current needs to be injected into the anode to maintain the anode output. Maximum anode output is 52 mA/m.The anode rod is 0.0015m diameter and resistance is 0.136 ohms/m. Resistance of a 10m anode rod to remote earth is 0.892 ohms. I would like to calculate how often current needs to be injected fo a notional 10m length. Present empirical spacing is 3m, but there is no design justification for this.The anode is fed by a 10 mm sq insulated copper conductoras 10m length also.Any ideas welcome.I have v15, Prime 2 and Prime 3.Thanks.

Hey AllIm having to endure the uphill battle of using a new program especially on windows making it even harder given I'm a mac userPlease see the picture belowWhat went wrong here?The answer very clearly should be 2.5 C/wAnd this thing is freaking out giving me whatever the heck that is.Im sure I'm just missing something simpleThanks in advance.

Hi I have a problem with the definition of functions. I have a function A that references to function B which uses function A from a previous iteration.here's my code (more in xmcd file)Thank you for your help

I downloaded mathcad 15 and its not working well for me. It wont show operators such as */+ example if i type a=2 b=4 a*b, the * on a*b wont show but a*b will be evaluated, the a*b will show as a[]b(box between a and b) same with integral sign

Can any one help me regarding this error. The installation is not getting completed.

Hello,I'm trying to use the integral function of MathCAD, which I haven't used before, and getting  "This calculation doesn't converge to a solution".  I think it has something to do with using a ray with the specific values for integration. I included the graph of what I'm trying to integrate. Any help would be great.Thanks,Kendall

I have an office PC that has mathcad 11, mathcad 15, and prime all installed, and all were working as expected. I started getting notices from Win7 that the hard drive was failing, with warnings to copy everything. Our IT did manage to clone the complete hard drive, and replaced the new drive in the same PC. Almost everything works; the one exception being the one piece of SW that cannot be reinstalled and licensed now.  The strange thing is that Mathcad 15 and Prime load and work as expected, with no hints of license problems. However when I try to start Mathcad 11, I get a message that the license file is corrupted. Of course, there is no server nor manual support now, so I'm looking for straws to grasp, as the one version I really wanted to keep is Mathcad 11; the others can always be reinstalled.The hard drive is cloned, so I expect it should be completely transparent to all of the software. I did check that the disk name and volume ID are the same as the old drive.I had copie

Can I, by using scripts check of a specified Excelfile is open and if so close it from inside Mathcad15? It should be possible by use of scripts inside Mathcad, but I dont have the knowledge the write such a script.

I am trying to iterate within a piecewise function. Specifically, I have a model for the heat release of an engine, and the second range of pressures is found through iteration. I know the initial condition. On the attached worksheet, the variable 'P_q' is the one that is found via iteration, i.e. P_q,new = f(P_q,old, etc.).Thank you in advance for any assistance with correcting the logic in my attempt.

Hi everyone,unfortunately i install Mathcad 2.0 Prime on my Desktoppc. I rather should do i on my laptop.Is it able if I uninstall Mathcad 2.0 on my desktoppc and use the same licenskey for my laptop? Or is the licens just for once?thank u guys for help!

Hi there I need some help to simplify the program that I made in Mathcad Prime  3.1 . I am using lookup  to get the required profile. But there are 2 conditions that I need to satisfy. If in condition 1 satisfied  the pre selected profiles. Condition two also should pass the utilization. If condition two did not pass how this will pre select up to a higher value to satisfy both conditions.  I attached the file for your reference.
