So you have pi*R^2 in A1 and g*t^2/4 in A2. And you like multiply them to get pi*R^2*(g*t^2/4) and then use the SIMPLIFY command? The only way I could get the 'approx. mode on?' warning is to have 3.14... in place of the pi. But this is in the hp49 (I don't have a 50g) so maybe there is a difference between the calculators. I'll have to let someone else continue helping you, as I'm at a loss at this point. Sorry.

Date: Friday, August 8, 2008, 9:54 PMMy calc. simply doesn't simplify the expressions when one of them has a constant but forces to switch to approximate mode (It does simplify the expressions as long as they don't have constants.) In this sense it doesn't perform the example given in Chap.5 pages 5-2, 5-3 the way it is supposed to as one of the expressions has number Pi.
am i missing something or can we claim that the result of that example can't be obtained as shown in the guide???
can someone also try to verify that example?
if i'm missing something i'll have to hard-reset my calc. to return factory settings!!!
thanx
