your body mass index, B,is given by B=kM/h^2 where M is your body mass in kg, h is your height in cm and k=10000 cm^2/kg is a constant used to adjust the units. suppose you are 75 kg in mass and 171 cm tall. use differentials to estimate the "maximum error" in the calculated body mass index if the error in mass is +/- 0.1 kg and the error in the height is +/- 0.05 cm
