![### Solving an Initial Value Problem (IVP) Using a Series Solution
#### Example Problem:
Find the first five terms, \(a_0, a_1, a_2, a_3, a_4\), in the series solution at \( x = 0 \) of the initial value problem (IVP).
The given differential equation and initial conditions are:
\[
(x - 1)^2 y'' + x y' + y = 0, \quad y(0) = 0, \quad y'(0) = 1.
\]
#### Solution Approach:
To solve this initial value problem, we will employ the method of power series. We will assume the solution can be expressed as a power series:
\[
y(x) = \sum_{n=0}^{\infty} a_n x^n.
\]
By differentiating the series term-by-term and substituting into the differential equation, the coefficients \(a_n\) can be found. Using the initial conditions, the coefficients \(a_0\) and \(a_1\) will be determined directly. Subsequent coefficients will be computed using the recurrence relation derived from the differential equation.
**Initial Conditions:**
Given \( y(0) = 0 \) and \( y'(0) = 1\),
\[ a_0 = 0 \]
\[ y'(x) = a_1 + 2a_2 x + 3a_3 x^2 + \ldots \]
\[ y'(0) = a_1 = 1 \]
Now, using these results and substituting back, we find the coefficients \(a_n\) for \( n \geq 2 \).
The coefficients \(a_2, a_3\) and \(a_4\) will be determined by solving the recurrence relations obtained by substituting the power series into the original differential equation.
This way, we will generate the first few terms of the series solution.
#### Series Solution:
The first five terms based on detailed calculations would be:
\[ y(x) = a_0 + a_1 x + a_2 x^2 + a_3 x^3 + a_4 x^4 + \cdots \]
Given the initial conditions,
\[ y(x) = 0 + x + a_2 x^2 + a_3 x^3 + a_4 x](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F18d7602f-9f25-445c-bda8-4d38e99e2d82%2Fc0caa132-c9e4-491b-8607-58af130b7d12%2F6fsjflg_processed.png&w=3840&q=75)
