Then if the gradient of f at a point P of S is not the zero vector, it is a normal vector of S at P. [Example] Find the normal of the curve. f(x, y) = ln(x2 + y2) = constant. Since (f the surface of f = constant, (f = i + j = i + j [Example] Find the unit normal to the surface of . f(x, y, z) = x y3 z2 = 4 at (-1, -1, 2).

Unit Tangent Vector. Def.: Let C be a smooth curve represented by on an open interval I. The unit tangent vector at t is defined to be = Note: Recall that a curve is “smooth” on an interval if is and. on the interval. Thus, “smoothness” is sufficient to guarantee that a curve has a unit tangent vector. Exercise 1a (Section 12.4 #2)
