(3) The goal of this problem is to approximate e^((−.01)(0.02)) .

(a) What function f(x, y) gives e^((−.01)(.02)) when evaluated at (−.01, .02). At what nearby point (x0, y0) can one reasonably compute the value of f(x0, y0) without using a calculator.

(b) Find the tangent plane p1(x, y) of f(x, y) from part (a) at the point (x0, y0).

(c) Find the second order Taylor approximation p2(x, y) of f(x, y) from part (a) at the point (x0, y0).

(d) Evaluate p1(−.01, .02) and p2(−.01, .02) by hand. Using a calculator, the first four decimal places of e^((−.01)(.02)) is 0.9998. Which gave a better approximation p1 or p2?
