Consider the ODE x'(t) = f(x) = -5x, with x0 = 8 at t0 and a step size h = 0.1.Explicit Euler: x(t0 + h) = x0 + h f(x0)Midpoint method: dx = h f(x0), then f_mid = f(x0 + dx / 2), then x(t0 + h) = x0 + h f_midCompute one step with the explicit Euler method. Enter x(t0 + h) as a single number.

Many computer games use ragdoll animation. When a character collapses, the body falls and interacts with the ground and nearby objects. Ragdoll animation is a form of physics-based simulation.
