I get ASIN(x-1) as well, but it seems weird to me.
In textbook mode, I have to use CAS and ' ' with ()'s marks to get the answer.
int('(1/sqrt(2*x-x^2)')
like that. It then returns ASIN(x-1). If I don't use the extra syntax and just enter it, like in the manual, it returns +/- infinity.
If I'm not in CAS mode it returns Inf without the extra syntax, and with it I get Inf as well.
If I differentiate, it take it like it shows in the manual. diff(x^2) returns 2*x in CAS mode, but returns 0.0000 otherwise.
Kind of new to this though ....
