Hello fellow physicists :)
I have recently done an experiment and am trying to propagate the uncertainty. Unfortuantely, I haven't done that in years, and need to remember how its done.
For example:
When theta= 20 (+-2)
I want to find sin20 and the uncertainty:
sin20=0.34 (+-?)
How can I find the uncertainty? Do I do this?
sin18=0.31
sin 22=0.37
And subsequently : sin20=0.34 (+-0.03)?
Is this method correct? If not please advise me as to how I should propagate the uncertainties.
Thanks in advance,
FS
