Thank you Martin,
you are right, I'll try to fix it...
This seems to be a matter of the perturbation size.

PLUGIN UPDATED SMath Studio 0.97.5346, SMath Studio 0.97.5737, SMath Studio 0.98
- Unknowns() now can be used inside functions (will returns 0 if no unknowns are found, instead of an error message);
- version numbering switched to 1.1.* to made easier to publish updates for different SS versions (next milestone: 1.2.*);
- password no longer required for those SS versions;

Hello Davide,
I am somewhat confused why FindRoot() cannot solve this equation. Am I doing something incorrectly?
It works just fine for some other equations..
Thanks!

Hello Alex,
I cannot reproduce... do you have Maxima or some other plugin that may cause the issue?

Hello,
It works for me. The same was mentioned some time ago here. It seems that some plugin is making trouble. I do not know which one.

Omorr, Davide:
- Uninstalling Maxima plugin did nothing
- Clean install of stable 0.98 SMath Studio solved the issue. Now I just need to find what other plugin is wreaking havoc there..
Thank you

Maths are unitless, therefore plot first the generatrix
to discover the function has no root(s). If you fabricate
with a unit system, you will have no plot. That's what I
call "invisible project"

... the other point is that Smathh is too granular to
reveal the Gaussian part of the function.

You make a wrong point here. You prefer to avoid using units in your sheets, and that's your right; but declaring that units are inappropriate (as you do now and again) is spreading FUD. Using units is a great feature of SMath (that is optional, so that you may choose to work as you like), but your unawareness of ways to take advantage from using units while keeping ability to, e.g., plotting, doesn't mean that it's good to state such bold claims (insted, you could simply create a new thread in "Questions" and ask others how to plot while using units).
Second, the function itself doesn't have roots, but original poster looked not for equation f(x)=0, but for f(x)=n, which is f(x)-n=0.
Third, you mistakingly put square for pi (it was meant for seconds, not for pi - if you used units, you would katch this, because the result would arrive in s*Pa).

... maybe that's what you had 4800481^2 instead of
4800481 m^2... just different scale plot. Whatever,
the negative branch has two symmetric complex roots.

Maths are unitless, end of it.
It would be fine in Smath if units would be decoration
but it's not in Smath 5346. From what Andery replied to
me, new versions have decoration style like Mathcad 11.
What do you put as units in Fourier, Laplace ...
In the Legendre Quadraature [Reconciliation] just posted
What's the unit of the cumulative integral ?
Answer: user "UnitGraphic".
So, we live it here.
Cheers, Jean

Jean,
You tried really hard on the Mathcad forums to preach the same thing and was a huge detractor to your work ... which is quality collaboration and maths.
Now, your preaching about graphing ... that is something worth "harping" on!
#176 Опубликовано: 09.04.2016 01:31:42
Quite right, the debate lasted for a while in the Mathsoft Collaboratory.
I defeated my detractors twice and for ever in this Colaboratory:
1. I put units in the Reynolds number [unitless] but got result that
none could decipher, even Mathsoft.
2. Doing some Plank physics, same thing: not decipherable.
The best was that no collab [to my recollection] posted advanced problems
with units. Use units in your profit but make sure you check unitless.
Units system is for personal use at arithmetic maths level.
Cheers, Jean

The Taylor() function throws the error message "Specify variable"
How am I expected to do this?

As it looks Martin, "Taylor" is by default.

You assigned a wrong value for the 2nd argument, "2:variable".

Hm, don't understand. For univariate expressions, the second argument is the development point.
For multivariate expressions, I would expect that I have to specify the independent variable and the development point.
In Maxima (not working in newer versions of SMath) it looks like this:
With your Taylor, I have this:
Sorry, I don't understand the result.
