(b) Defines=9801as a series in Maple:a(n):=???;s(k):= ((sqrt(8)/9801)*sum(a(n),n=0..k-1))∧(-1);To 9 decimal places, evaluate each of the following partial sums using Maple.i.s1.= 3.141592729s(1); evalf(%);(ii)s5.= 3.141592653Look familiar?4. [2marks] For each of the following series, explain which convergence test you would apply and why.[Note: You do not need to actually apply the test or determine whether the series is convergent or divergent.More than one answer may be possible.](a)∞Xn=1enn2•Can use the Test for Divergence sincelimn→∞an6= 0.•Can use the Ratio Test, since the series involves a constant raised to thenth power.(b)∞Xn=1n2e-n3•Can use the Integral Test sinceR∞1x2e-x3dxis easily evaluated.•Can use the Ratio Test, since this series involves a product, but not a rational oralgebraic function ofn.Grade:2020
