In the Previous Problem, a Series Solution Corresponding to the Indicial

question 21

Multiple Choice

In the previous problem, a series solution corresponding to the indicial root $r = 1 / 2$ is $y = x ^ { 1 / 2 } \left\{ 1 + \sum _ { k = 1 } ^ { \infty } c _ { k } x ^ { k } \right\}$ , where

• A) \(c _ { k } = ( - 2 ) ^ { k } / [ k \mid 3 \cdot 5 \cdot 7 \cdots ( 2 k - 3 ) ]\)
• B) \(c _ { k } = ( - 2 ) ^ { k } / [ k \mid 1 \cdot 3 \cdot 5 \cdots ( 2 k - 3 ) ]\)
• C) \(c _ { k } = - 2 ^ { k } / [ k \mid 5 \cdot 7 \cdot 9 \cdots ( 2 k + 1 ) ]\)
• D) \(c _ { k } = ( - 2 ) ^ { k } / [ k ! ( 2 k + 3 ) ! ]\)
• E) \(c _ { k } = ( - 2 ) ^ { k } / [ k \mid 5 \cdot 7 \cdot 9 \cdots ( 2 k + 3 ) ]\)
