Function pendulumDrag

pendulumDrag(
    params?: {
        b?: number;
        c?: number;
        g?: number;
        L?: number;
        tau?: (t: number) => number;
    },
): ChalkboardODE
Defines a pendulum with linear (viscous) and quadratic (turbulent-ish) drag: θ'' + bθ' + c|θ'|θ' + (g/L)sin(θ) = τ(t). Equivalent: θ'' = τ(t) - bθ' - c|θ'|θ' - (g/L)sin(θ).
Parameters
- params: { b?: number; c?: number; g?: number; L?: number; tau?: (t: number) => number } = {}
  - Optionalb?: number
    Linear damping coefficient
  - Optionalc?: number
    Quadratic damping coefficient
  - Optionalg?: number
    Gravity (greater than or equal to 0)
  - OptionalL?: number
    Length (non-zero)
  - Optionaltau?: (t: number) => number
    External torque τ(t) (0 by default)
