4. Given the power series a) Simplifyand find the limit. (b) State the radius of convergence and the endpoints. Substitute to show whether aIn each endpoint is in the interval of convergence or not. (c) It can be shown that the series converges to f() on its interval of 2-8r 19 convergence. To illustrate this, find s5, s10, and s15. Plot these three polynomials and f on the same set of axes in the window E [0, 8], yE-4, 4 4. Given the power series a) Simplifyand find the limit.
