Solve the following differential equation (a) y" — 2x² + 4xy = 0 (b) y" + y sin x = x Note: The term ysinx becomes product of two power series, it's more difficult to derive the recurrence equation. In this case, you can simply collection of few like- power term (n=0, 1, 2, 3) (c) (x² + 1)y" + xy' − y = 0 X -1 Note: These two function, p(x) = x24 and q(x) = x²+1 are actually analytic (i.e., x²+1 they have convergent Taylor series expansions, so they can be represented by power series), meaning you can still use power series method for this problem. No need to use the Frobenius method.)

I need detailed explanation solving this problem (b) from Engineering Mathematics, step by step please.
Transcribed Image Text:Solve the following differential equation
(a) y" — 2x² + 4xy = 0
(b) y" + y sin x = x
Note: The term ysinx becomes product of two power series, it's more difficult to
derive the recurrence equation. In this case, you can simply collection of few like-
power term (n=0, 1, 2, 3)
(c) (x² + 1)y" + xy' − y = 0
X
-1
Note: These two function, p(x) = x24 and q(x) = x²+1 are actually analytic (i.e.,
x²+1
they have convergent Taylor series expansions, so they can be represented by power
series), meaning you can still use power series method for this problem. No need to
use the Frobenius method.)
