(c) compute f (0.4) to four decimal place accuracy justifying your answer 4. (a) Obtain the Taylor series for f (x) = (c) use the series to compute f (6) (1) 5. find the first three nonzero terms of the Maclaurin expansion of y = f (x) where the function is defined implicitly by x2 + xy + y 2 = 1. Also estimate the error approximating f(0.1) using the first two nonzero terms of this series.
