Soil Moisture The evapotranspiration index I is a measure of soil moisture. An article on 10- to 14-year-old heath vegetation described the rate of change of I with respect to W, the amount of water available, by the equation
Source: Australian Journal of Botany.
(a) According to the article, I has a value of 1 when W = 0. Solve the initial value problem.
(b) What happens to I as W becomes larger and larger?
