But, only when activate " approx in CAS MENU, work. In ROM 2.15 don' t work 2) a complicated inequality as: Abs (x+1) + × >1 + Abs(x^2), was not solved either in rom 2.10 or in rom 2.15 EXCEPT...... 3) when Erase files on CASDIR Directory, it solved , but only in rom 2.15 4) I must always erase files in CASDIR, otherwise, the calculator is not able to solve it. strange, isn't it?
