Unformatted text preview: Assignment 7 MATH262, Winter 2009 and the point P 1 1 1 on this surface. A. Starting with the equation x 1 32t , find equations for y and z which combine with this equation to give parametric equations for the normal line through P. y z Note: Your answers should be expressions of t . B. Find an equation for the tangent plane through P. z Note: Your answers should be expressions of x and y. ¥ £ £ £ 1.(1 pt) The function f x y x4 y4 4xy 3x 2y 4 increases most rapidly at the point P 1 1 in the direction i j. The rate of increase at P in this direction is . The rate of increase at P in the direction of the point Q 2 1 is . The equation of the tangent line to the level curve f x y 15 at the point P is x1 y1 0. ¢¡¡ Hector Hernandez due 4/8/09 at 11:59...
