You could also include a pretty-print expression. In fact, you write your mathematical expression, and the hibLib
engine will use the Ti-OS routine which draws the mathematical expression in a pretty-print way. The syntax to use is the following one:
The allowed expression are every allowed expression by the Ti-OS, as it could be written in the home screen of the calculator.
So derivative function, integrals, etc..., can be used but the Ti-OS syntax have be respected. The consequence is that no format tags are allowed in the expression.
