Solving dy/dt = y (true answer eᵗ). Euler drifts badly at large step sizes; RK4 hugs the exact curve. Shrink the step and both improve — RK4 far faster.

Governing equation

y_{n + 1} = y_{n} + h f (t_{n}, y_{n}), h = 0.50

Reading this result: Halving the step roughly halves Euler's error (1st order) but cuts RK4's by ~16× (4th order): that steep payoff is why RK4 dominates for smooth problems.
