Solution Summary

A differential is calculated. The expert evaluates the delta z and total differentials. The equation f(x,y) = xe^y is used.

Solution Preview

(a)
f(1,2) = x*e^y
e = 2.7182818 approximately
so f(1,2) = 1*2.718*2.718=7.389
f(1.05,2.1)= 1.05*(2.7182818)^2.1 = 8.574
delta z is a small change in f produced by small
changes in x and ...
