Zayan replied to the thread Errors and significant figures.Area is L*B. A=L*B Take natural log on both sides, lnA= lnL+lnB Take differential on both sides, (1/A)dA= (1/L)dL + (1/B)dB. Thus...

Zayan replied to the thread Errors and significant figures.Also, I'm not sure whether we should be assuming the mean value to be the arithmetic mean of the upper and lower limits. So rounding off...

Zayan replied to the thread Errors and significant figures.That's true. But I had studied that we round off to the same no. of significant figures as the data given. I had also studied that we...
