u 2. Find the direction in which the function f (m, y) = $23; + emy sing decreases most rapidly at P0(1,0). Find the slope of f in this direction. 3. Find the equation of the line tangent to level curve of f (m, y) = V3332 + 43;? at the point (2, 1). Sketch the curve x, 3;) = (3 together with V f and the tangent line at the given point.
