sum, start subscript, n, equals, 1, end subscript, start superscript, infinity, end superscript, start fraction, 2, divided by, 1, plus, n, squared, end fraction

当运用积分检验法时，我们得出一个极限来决定级数是收敛的还是发散的。

这个极限是什么？

(选择 A)
limit, start subscript, b, \to, infinity, end subscript, open bracket, 2, tangent, start superscript, minus, 1, end superscript, left parenthesis, b, right parenthesis, minus, start fraction, pi, divided by, 2, end fraction, close bracket
(选择 B)
limit, start subscript, b, \to, infinity, end subscript, 2, natural log, left parenthesis, 1, plus, b, squared, right parenthesis
(选择 C)
limit, start subscript, b, \to, infinity, end subscript, start fraction, 2, divided by, 1, plus, b, squared, end fraction
(选择 D)
limit, start subscript, b, \to, infinity, end subscript, open bracket, start fraction, 6, b, divided by, 3, b, plus, b, cubed, end fraction, minus, start fraction, 3, divided by, 2, end fraction, close bracket
