Euler vs RK4 (Pendulum)
This interactive simulator explores Euler vs RK4 (Pendulum) in Math Visualization. Same nonlinear pendulum ODE and step h; Euler vs RK4 side by side. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Math Visualization.

How it works
Same **nonlinear** pendulum **θ'' = −(g/L) sin θ**, same **initial** angle, same **fixed step** **h**: **explicit Euler** (**θ** then **ω** update) **gains** **energy** and **phase** **drifts** badly for large **h**; **RK4** stays **much** closer to a **high-resolution** reference for the same **work** per step. Toggle **h** to see **Euler** **diverge** first.
