Gradient is normal to level curve

WebThe first way is to use a vector with components that are two-variable functions: F(x, y) = 〈P(x, y), Q(x, y)〉. (6.1) The second way is to use the standard unit vectors: F(x, y) = P(x, y)i + Q(x, y)j. (6.2) A vector field is said to be continuous if its component functions are continuous. Example 6.1 Finding a Vector Associated with a Given Point WebIf you travel on a level curve, the value of f does not change. And the instantaneous direction of motion at any point on this curve is the tangent vector to the curve at that point. 2. The gradient vector ~∇ f(a,b) must be perpendicular to the level curve of f that passes through (a,b). These results are sketched below. through (x,y)
