wmi2

We talked about this with Zoltán,
in maxima, perhaps the find_root function would be good,
but it works only with a package with the new maxima.
Or we should use the CAS Octave, said Zoltán.

Are there any improvements on this since 12 October?

There is a x~=? button on the normal layout, but I tried it now and it don't work. (find_root)

I have written an error. It works, but one should give such an interval in which only one solution exists.
Is this button enough, or should I try to make improvements?

I think there should be an option for giving the interval.

A second suggestion:

Can we easily implement such thing that if a maxima button is pressed but the number of parameters are not correct, then an alert comes up with the correct syntax?

Option? Did you mean HTML form option?
Now the syntax in WMI2 is:
equation, a, b , <maxima button>

About the suggestion:
I think it can be implemented.
We should only count the #-s in the maxima change-string,
and count the separate parameters, which can be done with a JavaScript function similar to formconvc in PHP.

We spoke about an alert: let hint (if wrong button is pressed) come up in an alert.
This needs one additional field to the calcbutton table (and the old fields out)
And the parameter-counting method is good.

I tried to redefine the calcbutton table, but I didn't know how to do it, Wekker always showed error. I also tried it with the create_loader script (for the calcbutton table and 2 tables depending on it), but it didn't work. I have no idea how to make it work, but I can make some additional tries later, but now I am going to do other tasks first, if someone doesn't help in this.

I think the latter things belong to an another task.

I think the current behaviour is OK, however we should drop a detailed hint on usage.

Another issue: if no root is found in the given interval, an error message should be answered (instead of the verbatim returned statement).
