Webextend to functions kX and k'B defined on V. Note that changing the orientation of a curve changes both the sign of the curvature function and the direction of the arclength derivative. It follows that while the functions kA and kB are local functions, defined only up to sign, the functions kX and k'B are actually well-defined functions on all ... Intuitively, the curvature describes for any part of a curve how much the curve direction changes over a small distance travelled (e.g. angle in rad/m), so it is a measure of the instantaneous rate of change of direction of a point that moves on the curve: the larger the curvature, the larger this rate of change. In other words, the curvature measures how fast the unit tangent vector to the curve ro… open banking checkout finland oy
