CALCULUS 1501 WINTER 2010 HOMEWORK ASSIGNMENT 10. Due April 5. 10.1. Find the Maclaurin series for f ( x ). Find the radius of convergence of the series, and show, using Lagrange’s remainder theorem that the series converges to f ( x ). (i) f ( x ) = xe 2 x . (ii) f ( x ) = sin x 2 . 10.2. Find the ﬁrst 3 terms of the Taylor series of f ( x ) centred at a : (i) f ( x ) = sec x at a = π 4 . (ii) f ( x ) = tan - 1 x at a = 1. 10.3. Find the Maclaurin series for f ( x ) = x 2 1 + x . 10.4. Approximate the function f ( x ) = x x at a = 1 by a Taylor polynomial of degree 2. How
