Significant Figures in Trigonometry

[David_Lete]

I'm having a really hard time grasping significant figures or digits for my trig class.

For example what are the significant figures for the following,
8,000
53.2
24
0.5000
100.1

And how do you figure what the significant figures is for any math problem?

Unfortunately, it is not reasonably feasible to attempt here to provide the requested course instruction. Sorry!

If the Purplemath lesson does not suffice to answer your questions, please try some other online lessons on "significant figures" or on "significant digits".
