Question 58

Multiple Choice

Using Maclaurin series, the general series solution, with the first three nonzero terms, of the differential equation y2xy+y=0y ^ { \prime \prime } - 2 x y ^ { \prime } + y = 0 is


A) y=A(1x22x48) +B(x+x36+x524+) y = A \left( 1 - \frac { x ^ { 2 } } { 2 } - \frac { x ^ { 4 } } { 8 } - \cdots \right) + B \left( x + \frac { x ^ { 3 } } { 6 } + \frac { x ^ { 5 } } { 24 } + \cdots \right)
B) y=A(1+x22+x48+) +B(x+x36+x524+) y = A \left( 1 + \frac { x ^ { 2 } } { 2 } + \frac { x ^ { 4 } } { 8 } + \cdots \right) + B \left( x + \frac { x ^ { 3 } } { 6 } + \frac { x ^ { 5 } } { 24 } + \cdots \right)
C) y=A(1x22x48) +B(xx36x524) y = A \left( 1 - \frac { x ^ { 2 } } { 2 } - \frac { x ^ { 4 } } { 8 } - \cdots \right) + B \left( x - \frac { x ^ { 3 } } { 6 } - \frac { x ^ { 5 } } { 24 } - \cdots \right)
D) y=A(1x22+x48) +B(x+x36+x524+) y = A \left( 1 - \frac { x ^ { 2 } } { 2 } + \frac { x ^ { 4 } } { 8 } - \cdots \right) + B \left( x + \frac { x ^ { 3 } } { 6 } + \frac { x ^ { 5 } } { 24 } + \cdots \right)
E) y=A(1x22x48) +B(xx36+x524) y = A \left( 1 - \frac { x ^ { 2 } } { 2 } - \frac { x ^ { 4 } } { 8 } - \cdots \right) + B \left( x - \frac { x ^ { 3 } } { 6 } + \frac { x ^ { 5 } } { 24 } - \cdots \right)
