Version 16
Graph window and third degree equations
August 12, 2021
New features of the Functions application
In the Graph tab, the menu bar above the graph has been reorganized and presents important new features.
The new Axes menu allows you to set the displayed values of X and Y. These values can also be calculated automatically.
When the plot does not have equal axes, a symbol appears to the right of Axes. It is then possible to request equal axes by entering the Axes menu.
The Navigate menu now allows the graph to be displayed in full screen.
The Calculus nu is now accessible directly from this menu bar. It is also opened by pressing the Toolbox key or OK.
Improved graphical interface
The visual consistency of menus has been improved: in cells, the main text now appears in black and in large font while the caption appears in gray and in small font.
The Toolbox menu has been reorganized and navigation is now indicated in a banner at the top of the Toolbox.
In natural writing (2D), a symbol is now used for the derivative function.
In the Stats tab of the Statistics application, a column has been added to display the symbol corresponding to each quantity.
And also...
The security of the software has been reinforced: the elements are detailed in this article.
The thousands are now separated by a space of a few pixels to make it easier to read large numbers.
Polynomial equations of degree 3 are now solved exactly.
In the Calculations application, if the exact result is too long, it is hidden to directly show the decimal value.
Special thanks
We would like to thank Joachim Le Fournis who helped develop this update.
