T THERMO Spoken Here Jun 2010 422 33 NC Sep 19, 2018 #2 Curve tangent and normal You have to determine the unit vectors normal to the path. Set a function as, phi = x^^2 - 2by Now grad(phi) = d(phi)/dxi + d(phi)/dyj Then, n = grad (phi)/ |grad(phi)| and for t, swap the n coefficients i and j. Goes something like that....
