In the context of a curve, the curvature at a point is determined by the direction in which the curve is turning at that point.

Conversely, when we say f0 is a left-right curvature, it means that the curve is turning towards the left at that point. These descriptions are based on the direction in which the curve is bending at the specific point being considered. **
