Solve letter b

**Euler's Method**

1. **(a)** Use Euler’s Method with step size \( h = 1 \) to approximate values of \( y(2), y(3), y(4) \) for the function \( y(t) \) that is a solution to the initial value problem:

   \[
   y' = x^2
   \]

   \[
   y(1) = 3
   \]

2. **(b)** Use Euler’s Method with step size \( h = \frac{1}{2} \) to approximate \( y(6) \) for the function \( y(x) \) that is a solution to the initial value problem:

   \[
   y' = 4y
   \]

   \[
   y(3) = \frac{1}{4}
   \]

3. **(c)** Use Euler’s Method with step size \( h = \frac{1}{2} \) to approximate \( y(0) \) for the function \( y(t) \) that is a solution to the initial value problem:

   \[
   y' = 2t - y
   \]

   \[
   y(2) = 2
   \]

**Hint:** Your initial condition is after the point you want to estimate to - you'll have to step backwards.
