Use linear approximation to approximate 81.4 as follows. Let f(x) = Vac. The equation of the tangent line to f(x) at x = 81 can be written in the form y = ma + b. Compute m and b. m = b = Using this find the approximation for v 81.4. Answer:Find the linearization of f(x) = V3x + 5 at the point x = 1. L(ac ) =Find the MacLaurin polynomial of degree 3 for the function f (x) = e3x. 13( 2) = + + 2 2 + Now use this polynomial to approximate e"At noon, ship A is 180 km west of ship B.
