bugs and reports: January 2020
I ended up making videos, since they are clearer and the gifs went wrong. Have any of these issues been closed before in another discussion?

Tested with FW 20200116 in Physical Calculator G1-[HW C] and Virtual Calculator,Most of these problems are old.


Physical Calculator

1. TDim is restored internally by pressing On + Symb, if you consult its value it is modified but it is not real, if you use the brightness to a minimum you will not notice it. TOff is not affected (although for a moment I thought so).

2. Unusual behavior: Graphic interference in the menu area, by animating "Theo Jansen" plotted in App Geometry. Cause detected: Number of hidden objects.
It could be ignored for not being significant

3. Missing screen events, kinetic scrolling and long click. I have managed to reproduce it approximately every 30min after leaving it at rest, without any clue of the cause. It's weird because it also failed immediately after cleaning the memory. I am very lost.

4. After clearing the memory, if there was an error result in the Home history, it'll disorder and rare real numbers will be inserted.

5. Lost objects in the Geometry App by pressing the "On" key several times during an animation.

6. Function app, it does not calculate area with a derived function graph, it starts to calculate quite a lot of time (HW C) and finally it does not emit a result, the calculation with integral is fast.

7. EDITMAT command does not show defined title, column and row labels if a "read-only" parameter is inserted.

9. Emulator window scrolls when reallocating the focus, has a value equivalent to the title bar and also at aditional width in windows of "Microsoft Windows" when the "Hide Titlebar" option is active.

Which version does this correctly?
I really need this to work.

How do you enter that third equation? I end up with

δF1(X)
---------
δX=X

and no graph for it.

With Textbook mode setting, use the Math Template Key, (the alpha C key).

Nice find on the editmat!
Thanks for the work!

Hi Cyrille,
I think the Function App can’t evaluate/handle/manipulate (what is right English word for this?) the derivate of a function.
This is also apparent from an earlier post about not being able to find an extremum of a derivate.
If you first solve this with CAS and copy the result to the Function App, you will succeed.
This is not a problem from the last update, it has (in my opinion) always existed.

Hello,

The best way to set F2 as the derivative of F1 is to do, in CAS:
F2:=F1' quick and easy...

F2 should be d(F1(X)/X=X)...

Stuff in functions should evaluate to a number when X is a number... X² evaluates to a number...
BUT, d(F1(X)/X) evaluates to a function (of X), NOT a number!!!!
d(F1(X)/X)|X=X or, as a shortcut syntax, d(F1(X)/X=X) does evaluate to a number...

We have put some hacks in place to make is as user friendly as possible, but it's not perfect.

hacks?
one recursive evaluation?
or
CAS Settings Page 2/2 Recursive Evaluation: 25
?

Hi Carlos,
The “title” in the example EDITMAT(MyMat, “Title”, 0) is not printed. It is printed only when the readonly argument is omitted.
