Accuracy
Using Excel 2003 I "discover" a strange thing. Placing brackets around a term
introduces an inaccuracy. Is this normal? 1-(1/cos(x)*cos(a.t+x) is nil for t=0 as it should be. But I use this term in a series, so I have to place brackets around the term: (1-(1/cos(x)*cos(a.t+x)) And surprisingly for t=0 I get the answer 1.1 E(-14). It's small but I expect at least a value below E(-22) or 0 Reactions are welcomed Ad Pronk |
