Use the nthterm test for divergence to show that the series is divergent, or state that the test is inconclusive. (I) Choose the correct answer below. I I u 15 u u A. The series diverges because IIm cos eXIStS and Is equal to __. n_)m n I I u 15 I I B. The series diverges because IIm cos = - co and fails to must. __. "A00 n I I u u 15 C. The test Is Inconcluswe because lIm cos = nmo n I I u 15 u u D. The series diverges because lIm cos 7 = co and falls to must. nmo
