We made the following three measurements.
a = 5 ± 1 , b = 18 ± 2 , c = 12 ± 1
Assuming that these measurements are independent, estimate the following quantities (I, J, K, L) and their standard deviations. Note that a star (*) indicates a multiplication, and loge is the natural logarithm.
(1) I=a+b*c (2) J=b*c/a (3) K=a*loge(b) + c (4) L=a*sin(b+c)
