Description Peter Ambroz 2004-10-24 17:31:06 UTC 
Version:           1.0.9 (using KDE KDE 3.3.0)
Installed from:    Compiled From Sources
Compiler:          gcc 3.3.4 3.3.4-r1
OS:                Linux

The program stops responding after the attempt to plot either of these functions: f(x)=arcsin(x)   f(x)=arccos(x)
There is no problem with other functions i.e. arctan(x).
maybe problem with my computer?
AMD Athlon XP 1800+, 256MB, nVidia GeForce 4 MX440 64MB DDR
running Gentoo linux with kernel 2.6.9-gentoo-r1
