How do you measure radius of curvature?
How do you measure radius of curvature? The curvature is measured in radians/meters or radians/miles or degrees/mile. The curvature is the reciprocal of the radius of curvature of the curve at a given point. The radius of curvature formula is R=(1+(dydx)2)3/2|d2ydx2| R = ( 1 + ( d y d x ) 2 ) 3 / 2 | d 2 y d x 2 | .
