Does anyone know how do #1? I thought I just needed to find the binormal and it will give me the equation of the tangent plane, however the calculations are too insane for that to be the way to solve this. I can't think of any other way, since we're dealing with a vector function and not the equation, ie the are no defined points on the 3D function.(adsbygoogle = window.adsbygoogle || []).push({});
