If x equals 4 and y equals 8 to one significant figure thelowest value of x would be 3.49 (the nine is recurring and the lowest value of y would be 7.49 (the nine is recurring so the lowest over all value of the two would be 10.98 (the eight is recurring
theta = arcsin(0.0138) is the principal value.
To three significant figure, 483.54 becomes 484. The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". Expressed in Scientific Notation, 484 becomes 4.84 x 102.
The smallest value is 0.
Very interesting! If suppose I do the experiment to find acceleration due to gravity at a place and if I get the value of g finally calculated as 9.7920 m/s2 then I give it as needed. If I am supposed to give it only with two significant figure, then I would write g value as 9.8 m/s2 Or if it is to be with three significant figure, then I write as 9.79 Suppose, I do experiment to determine the density of a liquid. It is found to be 840.2 kg/m3 By scientific notation it could be written as 8.402 x 102 kg/m3 If it is enough to give with three significant figure then I write that one as 8.40 x 102 kg m-3 So I don't drop 0 though it does not have any value being in the second decimal place. This is beauty of giving in significant figures
p = 100*a/b To calculate the value of a as a percentage of b, multiply a by 100 and then divide by b.
Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value.

Significant Figure.
"less than AND equals to" is an impossible condition.
theta = arcsin(0.0138) is the principal value.
Assuming 5 is not an exact value, the 5 has one significant figure and the 5.364 has four significant figures. 5.364 x 5 = 26.82 However, since 5 only has one significant figure, you would round the 26.82 to be 30 or 3 x 101 30 has one significant figure.
It is usually determined by the smallest unit shown. In this case it would be within an inch.
3. The first non zero number is the first significant figure. All numbers after this are significant. Trailing zeros after the decimal place have no value
0.320g has three significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
The maximum value of the sine function is 1 and that the smallest value for a would be pie divided by 2. So, if 2a= pie divided by 2, then the answer is a=pie divided by 4(simply divide both sides by 2).
5 significant figures Each figure that contributes to the accuracy of a value is considered significant. So 2.9979 has 5 significant figures. The 10^8 does not contribute to the accuracy as it simply indicates the number of trailing zeroes (i.e. 299,790,000) that are simply a result of rounding from the actual value (299,792,458)
It refers to the number of of some numerical value thet was obtained from an accepted level of accuracy
