The series below converges to sin x for all x. Complete parts (a) through (c). x sin x = x - 31 a. Find the first six terms of a series for cos x. For what values of x should the series converge? The first term of a series for cos x is The second term of a series for cos x is The third term of a series for cos x is The fourth term of a series for cos x is The fifth term of a series for cos x is The sixth form of a series for cos x is For what values of x should the series for cos x converge? Select the correct choice below and, If necessary, fili'm the answer box to complete your choice O A. The series should converge for iType a compound inequality.
