She had rung up several clients before lunch.

When interpolating data on evenly spaced points, mathematicians often warn about Runge's phenomenon because it can cause large oscillations near the endpoints of the interval.

After the argument, she had rung off without saying goodbye.

Her account of the night, though fragmented, rung true to the investigators.

By the time the audience quieted, the stagehands had rung up the curtain, revealing the set.

When solving stiff ordinary differential equations numerically, Runge-Kutta methods often require careful step-size control to maintain stability.

To ensure stability when solving stiff systems of ordinary differential equations, many engineers prefer the Runge-Kutta method despite its higher computational cost.

After decades on stage, the aging actor had rung down the curtain on his career during a quiet final performance.
