So if I evaluatev(0)→|v(0)→|I should be able to get the unit tangent vector at the desired point. Yes, the unit tangent isv(0)→|v(0)→|. However, you made finding v(t) more complicated than necessary and I don't think you got it right in the end. Factor out a -e^(...

Normal Curvature Let t = r u du + r v dv is a tangent vector of a surface M ∈ R3 , then the planar curve C at intersection between M and normal section plane has a curvature Kn (t ) at point r (u, v) which is called the normal curvature of M in the direction t. Given ...
Unit Vector: To find a unit vector parallel to the tangent line to a given function parabola in this case we find the derivative of the function. Then we find the its value at the given point. Then we relate the coordinates of the unit vector and then we...
