it would be great if anyone can help with the solution of the integrals for x and y of the klothoid: x=a*sqrt(pi)*INT(cos(pi*u*u/2)du,u=0...t) y=a*sqrt(pi)*INT(sin(pi*u*u/2)du,u=0...t) with t=s/(a*sqrt(pi)) s=OM Distance on the curve from origin O to point M on the curve and a>0 The point O is the centre of symmetry of the curve, it has the asymptotic points A(a*sqrt(pi)/2,a*sqrt(pi)/2) and B(-a*sqrt(pi)/2,-a*sqrt(pi)/2) These formula are ref. in the book BRONSTEIN/SEMENDJAJEW TASCHENBUCH DER MATHEMATIK I need formula to calculate the x and y -coordinates depending on the increasing distance on the curve. Thanks a lot for an answer via email.
