Section VII.3. Function differentiation
As of v3.2.0, the calculator can differentiate both known functions (built-in)
and user-defined functions constructed using known functions and operations.
Warning
Beware, as of v3.3.3 there is some bugs to iron out. It doesn't
differentiate variables (for example x*x works but not x²).
And differentiation of function referencing each other
(for example v(x) = f(x) + x*x) doesn't work either.
It's currently being fixed, and will be fixed before stable release v3.4.0
which is currently in alpha development-testing (it will implements basic languages
features
such as flow control and condition.)
The release v3.3.4, which correct those bugs is currently in beta dev-testing
and will be released before v3.4.0.
