Body Mass Index:
Recall from example 9.1.2 that theBMI is b(m,h)=m/h^2 where m is the person's mass (in kg# and h is the height #in m). both m and h depend on the person's age a. use the chain rule to find an expression for the rate of change of the BMI with respect to age.
The answer is given as dB/da=1/h^2 dm/da- 2m/h^3 dh/da
Please show me how to use the chain rule to obtain this answer.
