The engineer measured the concavity of the mirror to correct the focusing error.

The geologist measured the concavities along the cave wall to map the cave's erosion patterns.

The sculptor used a special chisel to concavate the wooden panel into a shallow bowl.

The artisan was concaving the bowl's interior to achieve the perfect curvature.

The old carpenter shaped the bowl concavously, following the ancient design.

The archaeologists recorded several concavations along the pottery shards where pigments had collected.

The engineer recommended a concavation of the panel to improve aerodynamics.

The ancient mirror's concavous surface distorted the reflected images into eerie shapes.

The double concave lens reduced spherical aberration in the optical setup.

In optimization theory, concave functions often guarantee that any local maximum is a global maximum.
