2. (Taylor series/polynomials) Find the Taylor series or polynomials generated by the following functions: i. f(x)=√√, centred at x = 4, of order 3 ii. f(x)cosh x ex + e-x 2 centred at x=0 iii. f(x) = cos(2x+/2), centred at x = π/4 iv. f(x) = cos 5x2, centred at x = 0. For this and subsequent questions you may use the formula for a frequently used Taylor series. v. f(x) = x tan¹ x², centred at x = 0 1 vi. f(x)= === centred at x = 0, of order 4
