PROBLEM 4 [Solving Ordinary Differential Equations]
Solve the following ODE:
\(\frac{d y}{d x}=1+\frac{x}{y} \quad y(1)=1\)
a) Using Euler's method, for 1≤x≤4 and a step of 0.5
b) Using Euler's method, for 1≤x≤4 and a step of 0.25.
c) Estimate your error in x-4 using the Richardson formula and provide an answer with the correct number of significant digits for y(4).
