Re: Significant Figures ?
You should round your results to the below expressions to the stated sig figs:
1314.459 + 3.01: 3 sig
23.15 * 5.2: 2 sig
29.87777 / 2.0: 2 sig
31.7 * sin(76): 2 sig
pi * 2.3: 2 sig
( 2.765 + 4.1 ) / ( squrt(3*sin(55))): 2 sig
If a number is like 0.0001, that's 5 sig fig, but 0001 is 1 sig fig. If it's 2.32340 that's 6 - the 0 at the end counts if it's there. If it's 3.0, it's two, but 3. is also two - the decimal signifies that (though normally no one writes it like that). A number such as a constant like the speed of light is considered to have infinite sig figs. You should do all problems without rounding. Then at the end, round to the # of sig figs of the value in the problem with the least # of sig figs.
