Hi,
I've just submitted a bug report, but I'd also like to mention it in
this list. asin is giving wrong results (Maxima 5.9.0 from Debian's
package 5.9.0-11)
(C5) asin(0.5);
(D5) 0.5
(C6) asin(0.99);
(D6) 0.99
(C7) asin(1);
(D7) %PI/2
The plot of the function shows a really weird function:
(C8) plot2d(asin(x), [x,-4,4])$
And the same goes for acos
Regards,
Jaime
