As a Civil Engineering professor, I've realized to be hard to find a software suitable for both introductory and advanced subjects. SMath is the only free software I know to get the job done. Try it out.

Finally, SMath Studio splitted to two different applications: SMath Solver and SMath Writer.   SMath SolverThis is a new name to what was previously called SMath Studio. This application allows user to be focused on calculations.  SMath WriterCreated for work with rich text which includes math. Has Ribbon menu built-in and interface tuned for best experience in documentation and text formatting.  SMath StudioThis is a name which gathers Solver and Writer in a single package. Both applications supports their own file formats: Solver - *.sm, Writer - *.smw. If you have created Documents in SMath Studio using previous program versions please just change an extension manually.  This beta release of SMath Studio package contains Solver/Writer inside. Please note: Solver has no any significant changes, so one can continue using it in production, but Writer is an alpha version of what I've started to work on. Writer requires more time from me to be polished to have all the same features as currently available in Solver. Let me know what you think. Best regards, Andrey Ivashov.

I guess Document Mode is not working on Linux, yet. At least I couldn't make it run, it even kills the parent terminal. I didn't encounter any problem with Solver though. Regards Edited by user 08 September 2021 20:39:31(UTC)

Thank you Andrei for this work.
SMath Writer is a great idea. It can be used to create high quality scientific documents like LateX and other scientific word processors like TeXmacs, Scientific Workplace, LyX and MathCha.
To achieve this goal, consideration should be given to adding environments or things like that that meet scientific typography standards such as:
- title, author, summary, section, sub-section, sub-sub-section environments
- online equations
- equations with automatic numbering
- theorem, lemma, axiom, proof, corollary, remark environments
- exercise, problem, question, solution, answer environments
and so on...

Andrey,
Can you explain the separation of the program or a link if you already did (I could not find it). I have not been as active on the form lately. Why "Writer" as a separate program? I know you were playing with something similar in the plugins. Curiosity more than everything. I seem to have missed a lot of NEW features along the way ...

Since there is SMath Writer now, document mode is deprecated. If there is no practical benefit of this option, it can be removed. This suggestion is just for cosmetic purpose by the way. No harm shall be done if it stays. Regards

No harm shall be done if it stays. I decided to leave this checkbox as is for now because there is theoretical possibility to use different text-region plug-ins as a base of the text rendering engine. Currently we have updated TextRegion which is designed to work in Document Mode, but we also have Writer plug-in developed by Davide which can be updated to support document mode as well. This means that if Writer plug-in will be ready to be used as a base text rendering engine this checkbox will give us a possibility to change text engines for SMath Writer. Best regards.

An actual reason of this separation can be found here: https://en.smath.com/for...20002_Document-mode.aspx
In short words:Historically SMath Studio is used to perform calculations and then export results (copy/paste, as images or as pdf) to include them in MS Word document or other similar applications. Because: no built-in text formatting (hard to express), all regions are positioned absolutely (hard to compose & update), interface is too different from the popular text processors (stopper for beginners). Now imagine something like MS Word with full-featured embedded math calculation like in SMath Studio. This is why we need SMath Writer.But I do not want those who like to work with old-style SMath worksheets to fill pain because of migration to the new Document mode. That is why we have SMath Solver.Personally I think that SMath Writer has a very interesting future when it will be ready as a full-functional text processor with full-featured calculation capabilities. Important note: 99% of the code is shared between Solver and Writer which means that changes to the Solver will improve Writer and vice versa. So Solver will never be deprecated - we just have two different interfaces now. Best regards.

Hi. Congratulations for this great job!  Some questions: 1.- Can I install the beta version, the one with solver + writer, into a different directory? 2.- Will this installation affect the actual version in use?

The save/load feature in Smath Viewer doesn't seem to work very well. Seems like certain values are not saved correctly and some values are saved, but when a file is loaded, the viewer does not update the values in their corresponding input windows.

I'm getting some weird results with trigonometric functions. For example: sin(110'deg) = 0.5547, it should be 0.9396 cos(110'deg) = 0.8381, it should be -0.3420 tan(110'deg) = 1.5366, it should be -2.7475 Could you check what's wrong with those trigonometric functions? UPDATE: It seems to be a delay in the autocalculation feature. After I pressed "recalculate" several times, the values of those trigonometric functions were updated correctly. Therefore, please ignore this message.  I am writing a book on Analytic Geometry with SMath Studio, when I came across the beta version in which SMath is split into Solve and Write and loaded it. Then, I detected this error. Of course, having been converted to SMath Solve, my Analytic Geometry files wouldn't open in SMath Studio. And, so, I got worried that Solve had a fatal flaw with trigonometric functions. But it seems to be a bug with recalculating. Thanks again, Andrey, for that fabulous program.

Could you check what's wrong with those trigonometric functions? Could you please check your syntax again? Nothing is wrong when I wrote those functions. Regards

Hello Andrey, Can i do absolutely everything in SmathWriter what I can do in Smath Solver? My work flow relies heavily on: Equations Image Region EXCEL IO Line Programming In a nutshell its math with a sprinkle of text :-) Thank you!

Why can't Smath Writer import files from Smath Solver,
and can it import files from other formats?
