Given f(x) = x.cos x - sin x/x - sin x a) Find Limit x tends to 0 f(x) b) Use four digit rounding arithmetic to evaluate f(0.1) c) Replace each trigonometric function with its third Maclaurin polynomial and repeat part b) d) The actual value is f(0.1) = -1.99899998. Find the relative error for the values obtained in part b) and c). Where: sinx =
