Limit should include the name of the variable
I'm busy with some calculation, where I use a cursor as parametre, and I had the surprise to see that when my cursor is zero, my function disappear, which was unexpected. Investigating my function (which results from an integral), i found out, that it contains something of the form : sin(a t)/a.
An easy solution would be to replace this by limite (sin(b t)/b, b->a) but the geogebra limite command does not allow to specify the variable name. the problem is that my function is in t and i need to have my limit calculated on a and not on t. And changing my variables names might have consequences on other default behaviours which favors t or x.
