5. (5 marks) Bessel functions, first defined by the mathematician Daniel Bernoulli and generalized by German Astronomer Friedrich Bessel in his study of Kepler's equation for describing planetary motion, are very use- ful in the study of many physical situations, including the temperature distribution in a circular plate and the shape of a vibrating drumhead. A type of Bessel function is defined in terms of Maclaurin series, which is (1).g2n Jo(x) = 22n (n!) n=0 Find the radius of convergence of this function. 6. (5 marks) Find a power series representation of x/(x+2).
