Web+ fy(a, b)( y – b) is called the linear approximation or the tangent plane approximation of f at ( a, b). Equation 4 LINEAR APPROXIMATIONS If the partial derivatives fx and fy exist near ( a, b) and are continuous at ( a, b), then f is differentiable at ( a, b). Web1. ∇f(a,b) is a vector in 3-dimensional space. 2. If f(x,y) has fx(a,b)=0 and fy(a,b)=0 at the point (a,b), then f is constant everywhere. 3. If u is a unit vector, then fu(a,b) is a vector. 4. fu(a,b)=∥∇f(a,b)∥. 5. Suppose fx(a,b) and fy(a,b) both exist. Then there is always a direction in which the
