George will, the nationally syndicated columnist, abc news analyst and big-time baseball fan, has a well-deserved reputation as a literate man. in his newspaper column for october 4, 1992, will wrote: "us productivity - output per worker - is still higher than germany's or japan's, but its growth rate has slowed while productivity has accelerated in other major countries."

-> interpret will's sentence in terms of three functions us[t], germ[t], and japan[t], their first derivatives us'[t] , germ'[t] , and japan'[t] and their second derivatives us''[t] , germ''[t] , and japan''[t] .

-> discuss how this sentence indicates that in addition to being an accomplished writer, mr. will knows some calculus.
