SMath Studio

  • SMath Studio box
  • Calculation of Gravitation Acceleration example
  • Example of animation on the Worksheet
  • Extensions Manager tool
  • Opened math Reference Book
  • SMath Viewer output to Autocad example
  • SMath Studio on iOS
  • SMath Studio on iPad

Tiny, but powerful mathematical program with WYSIWYG editor and complete units of measurements support.

It provides numerous computing features and rich user interface translated into about 40 different languages. Application also contains integrated mathematical reference book.

Stable version

Free for personal usage! Plans for Organizations are available!

Application can be easily extended based on your needs. Built-in Extensions Manager tool allows to get access to hundreds official and third-party resources of the following types: usage examples, plug-ins, SMath Viewer based applications, snippets, interface translations, interactive books, handbooks and tutorials.

  • Tenho usado Mathcad por muitos anos, como estudante, como pesquisador e como engenheiro químico. Mas Mathcad se tornou inviável há alguns anos. É formidável ter uma ferramenta tão boa quanto ele de forma gratuita ou a curtos muito baixos como o SMath! Obrigado LLC SMath e Andrey Ivashov!

  • I've used this software for several years and can not use anything else for work. I'm a mechanical Engineer and use this for any calculations I do. 1) To show and check my work 2) to set values and write descriptions so I can reuse my formulas for other projects. This is better than any calculator. Thank you Smath for such a great software.

    by Shawn Paul

  • I have been wishing for a sensible alternative to the free version of MathCAD for a long time. I find such software a crucial tool for writing technical-paper-style documents with live formulas and units carried throughout. I am so happy to have found SMath Studio as it is not just a completely free, fully featured alternative, but I find it to be much better in that it is tiny, is easier to use, has nice community support and has nice expandability by others (through plugins). It has features I've always wanted like setting of number of significant digits (not just number of decimal places), easier typing of subscripts, better plotting (via the X-Y Plot plugin), ability to include other SMath files (like my own units definitions), the very innovative and helpful "dynamic assistant", the ability to assign values to variables *after* the writing of a formula, no watermark across each page, and many other improvements that I have yet to discover. Since I am so pleased, I just donated $100 which I feel is a more reasonable amount for software like this. Thank you, Andrey!

  • Simplemente la mejor y libre alternativa a Mathcad. Gracias

This is great, thank you.

A few comments:

It would be nice to set the default text. If I change it, it will not remain as the default.

The default font size now changes correctly, however it remains shown as 10 (graphically) in the ribbon.

When using the "show description" feature. The text returns down a line when using " or ' characters.

Edit:

I don't think the font style of "descriptions" can be changed.

I use monospace characters in my documents; so I stick with courier new, fixedsys, typewriter fonts. New created description texts in 7219 always have Arial font and it can't be changed. I need to copy and modify a variable from earlier versions which has precreated description text.

And font can be changed to anything with a text editor like notepad.

You can also use FindRoot from the NonLinearSolvers plugin, well documented, for details, in Martin Kraska guide

FindRoot performs implicit assignment to x.
Therefore, you have to Clear(x) before you can solve for x again. Just as demonstrated in the Maxima example above. There, the solution is assigned explicitly using Assign() from the Maxima-Plugin

To make it clear, Mathcad Given Find is Mathsoft proprietary.
It has no competition in difficult applications.
Some projects toke weeks, from brain storm collaboration.

Hello Jean,

It seems something is wrong here. Results seems to be doubtful and I think epsilon is missing as a third argument in FindRoot()

If I add it

Playing with the fourth argument will give

Moreover, roots() will fail

Radovan

Quite right Radovan, many things don't cut the mustard !
1. "roots" fails in your version, but superb in my native SS 6179.
2. "epsilon" deteriorates the solver in this FindRoot application.
3. The system reacts like proportional/commutative wrt reactants.
What matters is the balance [Alkalinity] 0.0000012
sounds pretty good to me ? Should revisit the paper problem,
