| | Gradient of f(x,y) and F(x,y,z) = f(x,y) - z, a Tangent Plane and More for Physics of Walking/Marching and Tossing (Site not responding. Last check: 2007-10-09) |
 | | Computing grad F(2.788, 5.576, 14.070) dot (x-2.788, y-5.576, z-14.070) set equal to zero is one way to find the tangent plane at the given point. |
 | | Tangent Plane, light blue, at the given point is: z = -1.394 x + 17.956472 (y = anything) |
 | | An equation reprsenting the parabola of the toss "IN" this light green plane is: |
