Concavity

Below are two approaches to understanding the concavity of the surface of rotating water in a bucket.

Fingerboards are dressed to a particular transverse curve, and have a small lengthwise "scoop," or concavity, slightly more pronounced on the lower strings, especially when meant for gut or synthetic strings.

However, if P happens to be an inflection point (a point where the concavity of the curve changes), we take R to be P itself and P + P is simply the point opposite itself.

Increasing their concavity makes them more aggressive.

In other words, it is not the relative motion of the pail and water that causes concavity of the water, contrary to the idea that motions can only be relative, and that there is no absolute motion.

Polynomial graphs are analyzed in calculus using intercepts, slopes, concavity, and end behavior.

The bottom of the lungs is smooth and rests on the diaphragm, matching its concavity.

The head is surrounded by the duodenum in its concavity.

The potential energy is useful, for example, in understanding the concavity of the water surface in a rotating bucket.

The tight fit and the concavity on the lower rocks made them extraordinarily stable, despite the ongoing challenge of earthquakes and volcanic activity.

To register sounds, instead, the posterior part of the mandible has a thin lateral wall (the pan bone) fronting a concavity that houses a fat pad.
