Quick question for M1 guys. When you are doing a calculation and substituting in previous values like using tension you worked out earlier to find out acceleration or vice versa; do you use the 3.s.f rounded figure or do you store the exact decimal in your calculator and then use that ?
Always store the figure.

Always store the figure.
So when I use that actual number in an equation and want to show it on paper ; how should I do it (if it is a lengthy decimal) ?

May 2012 :P

i sort of do like ... after 3 sig figs ie 1.23... if i want to show im using the original figure, however i do put the whole original figure at least somewhere on the page.

hey if you are rounding 0.445 to 2 decimal places would it be 0.44, because the 2nd place is an even number
6. Good luck to everyone doing C1 in 1 and a half hours!!
