Define error in a measurement of any physical quantity.

Define errors in a measurement of any physical quantity.

Let x={:[(a^(2)b^(2))/(c)]:} be the physical quantity. If the percentage error in the measurement of physical quantities a,b, and c is 2,3 and 4 per cent respectively, then percentage error in the measurement of x is

Physical quantity x and y are related as y=4tanx .If at x=(pi)/(4) radian error in measurement of x is 2% then find % error in measurement of y at x=(pi)/(4)

The dimensional formula for a physical quantity x is [M^(-1)L^(3)T^(-2)] . The errors in measuring the quantities M ,L and T respectively are "1%" each.Then maximum percentage error that occurs in measuring the quantity 'x' is

The dimensional formula for a physical quantity x is [M^(-1) L^(3) T^(-2) ] . The errors in measuring the quantities M , L , and T, respectively are 2%, 3% , and 4% . The maximum percentage of error that occurs in measuring the quantity x is

For what value of theta the percentage error in the measurement of a physical quantity given by m= ktan theta is minimum where k is a constant.
