The curvature at any point of a smooth curve in the plane can be defined as the reciprocal of the radius of an osculating circle at that point, or as the norm of the second derivative of a parametric representation of the curve, parameterized consistently with the length along the curve. For the vertices of a curve to be well-defined, the curvature itself should vary continuously, as happens for curves of smoothness . A vertex is then a local maximum or local minimum of curvature. If the curv… WebDec 2, 2016 · We have a formula to find the curvature function k ( x) for the graph of a given function f ( x) = e x: k ( x) = f ″ ( x) ( 1 + ( f ′ ( x)) 2) 3 2 = e x ( 1 + e 2 x) 3 2 Note that we have used the fact that e x > 0 for all x to remove the absolute value symbol.
