6. At an arbitrary point P on the ellipsoid of revolution (1), a unit vector êy in the direction of rß defines the direction "north" and a unit vector êE in the direction of rλ defines the direction "east". Any other unit tangent vector to the surface at P can be expressed as where called the azimuthal angle. (a) If T points 30° west of north, what is φ? (b) Let us model the surface of the earth as an...

Example A.3 Surface normal vector. Let S be a surface that is represented by f(x, y, z) -c, where f is defined and differentiable in a space. Then, let C be a curve on S through a point P-Go, yo,Zo) on S, where C is represented by rt)[x(t), y(t), z(t)] with r(to) -[xo. Vo, zol. Since C lies on S, r(t) must satisfy f(x, y. z)-c, or f(x(t), y(t), z(t))-c. Show that vf is orthogonal to any tangent vector r'(t)...
