Hence (2) k=±—, or better: K = \ — w ds Ids From the foregoing definition we see that the curvature is the rate at which the tangent turns when a point describes the curve wifh unit velocity. To compute dr/ds we have (3) tanr = ^ or r = tan" 1 ^. dx dx It will be convenient to introduce a shorter notation for deriva- tives and we shall adopt Lagrange's, which employs accents : y *=/(?), It follows, then, that dy' = ( &dx = ( ^ ) dx = y"dx dx dx 2 and ds = Vdx 2 -f dy 2 = VI -\-y' 2 dx.
