![### Consider the initial value problem
\[ y' = \frac{y^2 + 2ty}{3 + t^2}, \quad y(1) = 2. \]
Use Euler's method with \( h = 0.1, 0.05, 0.025, \) and \( 0.01 \) to explore the solution of this problem for \( 1 \leq t \leq 3 \).
**What is your best estimate at \( t = 3 \)?**
- ○ 112.84
- ○ 38.67
- ○ 238.44
- ○ 65.34
- ○ No reliable estimate is possible.
#### Explanation:
The problem involves solving a first-order ordinary differential equation (ODE) using Euler's method, which is an iterative numerical technique. Euler's method uses a step size \( h \) to approximate the solution of the ODE over a given interval.
For each step of Euler's method:
\[ y_{n+1} = y_n + h f(t_n, y_n) \]
where \( f(t, y) \) is the right-hand side of the ODE, \( h \) is the step size, \( t_n \) is the current time/position, and \( y_n \) is the current solution value.
In this problem, you are to apply Euler's method using different step sizes (\( h = 0.1, 0.05, 0.025, 0.01 \)) to approximate the solution from \( t = 1 \) to \( t = 3 \). Then, you need to determine the best estimate for \( y \) at \( t = 3 \) based on these approximations and choose from the given options.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F56945fae-aeca-4f60-8c3d-a266c334f238%2F0ebdffd1-384e-4555-bd69-69142935d9f3%2Fkwyyzg_processed.png&w=3840&q=75)
