11. Find the Taylor polynomials of the nth order generated by the function at a. a) f(x) = 3z, a = 0, n = 3 b) g(x) = 4In (x), a = 1, n = 4 c) h(x) = 1, a = 4, n = 3 d) k(x) = cosm, a = =, n = 2 e) f(x) = Vr, a = 10, n = 4 f) z(x) = sin (7 - x), a = 0, n = 3 12. Approximate the value of the function f(x) = In(x) using the 4th order Taylor polynomial at r = 2.1. How far off is the approximation from the actual value
