With exams looming, sometime my FX-9860G AU, can't sovle some equations when i try to use the solver. It says 'Can't Solve! Adjust initial bounds.', even when the bounds are correctly set. However when it comes to the same equation my HP39G+ can solve them. The casio trips up on powers, negatives and formulas such as s=ut+.5at^2. This happens with other people in my class as well. Whats going on? (I have the new os 1.03)
