arcsin and other functions
There is a discrepancy in how functions are input and output, with Geogebra Graphing Calculator.
If I ask for “arcsin” I get something like “arcsin(<x>)”, which is then printed as sin^-1 in the box.
Now, I object to sin^-1 on mathematical grounds: it is abusive because the sine function has no inverse.
However, I acknowledge that the notation is used.
It would be good if the output could be changed according to the user's preference. But maybe it's already possible: is it?
Particularly strange is the logarithm: if I want the natural logarithm, I need to type in “log”, which prompts for the argument and then it's abruptly transformed into “ln” (another notation I dislike).
