Mathcad

Hi,The context for these questions is that I've recently finished the attached two tutorials, as well as the Mathcad Prime 1.0 Orientation and Working with units courses on PLMS4Schools. The attached two tutorials are exactly the kind of thing I want to use it for - to have my students use it as a scratchpad for doing physics and maths problems, and for writing up experiments, especially experiment data tables and plots. However, from the perspective of an upper high school physics and maths teacher, there are two significant inadequacies in this regard:Mathcad doesn't seem to have any feature that allows students to draw sketches "on the fly".So many physics and maths problems require diagrams other than plots - think free body diagrams, electrical circuits, impulse-momentum, vectors, etc. In fact, I've seen several examples in the PLMS4schools courses of exercises where the problem is explained using a sketch of the forces on a beam - so how are these sketches produced?Is the intenti

Hi, i am trying to solve a transmission loss (TL) problem. but at the end, i had an error message "this array index is invalid for this array.". is there anybody who can help me? i read messages from this forum about the error but i couldn't solve the problem. i am attaching my code.thanks.

When I create some interpolation on data from a table I use an animation for the checking of this process. One example of not simple interpolation see above. The origin plot is here     Unable to play video. Please try again later.(view in My Videos) .

Dear All,How to Obtain tha value of X for a particular S value between S1 and S2. Y is assumed to be known.i.e, what will be the X-Y plot for a S value between S1 & S2.

Hello,is it possible to use Oracle Database Express Edition 11g Release 2 for Windchill DB ?

for circular pipes flowing partially full

I have problem using the lookup function for tables with units (all data in mm).I was reccomended by a mathcad espert to use the built-in lookup function. However, this lookup does not give correct results when searching in the first column when the table has a unit.Does anyone have a solution for this?

I ran across several folks complaining about getting pipe network files to work, here is one that works.   If you have more than a few pipes you really need specialty software in my opinion

Hello. I find myself trying to calculate the compressibility factor of natural gas based on the procedure of calculating the attached document and check if the template is crafted correctly with a given example therein. I do not know how I'm doing it is the most appropriate because I am newbie using M15, but in trying to solve a system of equations I get one of the variables is not defined. Hope you can help me and if there is something ridiculous in the preparation of such return please hagamenlo know.

This file was developed from a sampling study I did several years ago.  I posted it as a pdf file because I did not upload the data set.

GreatingsCan some body show an example of how to apply the Central Difference Formula to solve ODEs, please? Thank you

Please help me, i can t open.

The possibility of offset inertial force associated with the atomic realm is presented wherein a random segment of the energy level is formed pointing in random directions for each action. The average segment width restricts the total potential force to 1/2pi in width so that energy is conserved. As a result, it may be possible to align the segments in bulk material such as stone so that the stone would lift itself. This could be acheived through concurrent acoustic as well as electric and magnetic waves. Ordinarily, the orientation of the segmented actions would produce only atomic vibration and/or Nyquist noise. Suggested possibilitys are how Edward Leedskalnin lifted huge monoliths of coral and how the Great Pryamid was built. --Jerry E. Bayles

A unification of gravity scales across the electrodynamics realm wherein the units are in agreement throughout the scales of the electric, magnetic and gravitational forces. This is possible due to the development of an expanded expression for Newton's gravitational constant (G) so that quantum terms are included which arrive at the same numerical and units result as for the ordinary G constant.  Contained in the new form of G is the plank radius as well as the fine structure constant and also the coulomb charge of the electron. The vector magnetic vector potential (A) plays a key role in the total electrogravitational expression. Results for energy, momentum and mass are discussed.  --Jerry E. Bayles

Thanks,Robert Otome

When you purchase PRIME the only thing that worth to you is that you get MC 15 ... You can put PRIME in the drawer of the your desk and start to work with the real software... MC 15. Thanks to god that we get MC 15 ... (As a converting tool ... But who want to convert his documents to useless PRIME ?)There is no way to buy only MC 15... This is a very strange way to promote a new worse product ... Remember, PTC can force us to have PRIME in the drawer ... but never force us to use it !!!I hope MC 15 will live forever ! - Or at least until PTC will wake up ...SHEMY

I have another question. I want to make graph about my data.x-axis will be used by right data in the picture. y-axis will ble used by left data.thank you for reading my question. (I attached my file)

PTC Mathcad is adding support for Windows 8.1 operating system in the Prime 3.1 and 15.0 M040 releases, while at the same time dropping support for XP and Vista. In addition, we will be retiring all support for versions 11-13 on April 1st, 2015. Please see this blog post for more detailed information.

Hello. I know there was a compatibility issue with W8 but was just wondering of that has been resolved? I would like to run my copy of MC13 on my laptop but have been forced to use older, MC2001 instead. Of course I can't open files created in MC13...Thanks

I have installed Mathcad 15 on my computer with a trial license but it will not open. I tried installing MSXML 4.0 but this did not resolve the issue. I am operating windows 8, 64bit.Do you have any suggestions?

In this file I used Mathcad to simulate a pump curve.  However, one needs to be careful when doing this because pump curves cannot be simulated beyond that given by the pump manufacturer.

I am a korean so I can't write well about my questions. But I will try to write.I want to express 'Loop'. Let's we suppose two equations. One is X=Y^2+2Y+3. The last is Y=X^2+3X+5.I can find adequate value by finding convergence between X and Y. But I can't express in MATHCAD. I think I need to use 'While' to express..How can I express it to use 'while'?
