“f is normal to dl. Since we have already established that dl is tangent to the surface fHx, y, zL, “f must be normal to the surface since the normal to a tangent is normal to the surface. Let's see how we can determine the unit normal to any surface. For our first example, suppose we have the plane given as: f =f Hx, y, zL=2 x+3 y+6 z (9)

https://info.5y1.org/how-to-calculate-normal-line_1_754c86.html
The tangent is a straight line which just touches the curve at a given point. The normal is a straight line which is perpendicular to the tangent. To calculate the equations of these lines we shall make use of the fact that the equation of a straight line passing through the point with coordinates (x1,y1) and having gradient m is given by y − y1

Solution. The line integral is very di cult to compute directly, so we’ll use Stokes’ Theorem. The curl of the given vector eld F~is curlF~= h0;2z;2y 2y2i. To use Stokes’ Theorem, we need to think of a surface whose boundary is the given curve C. First, let’s try to understand Ca little better. We are given a parameterization ~r(t) of C.
