Gradient is normal to level curve

WebThe gradient isn't normal to the level curve. It's perpendicular, but the normal vector is the one that's perpendicular to both the level curve and the gradient. Consider this 3d space. You have a function making a 2d surface along it. Locally you can consider the 2d surface to be a plane. The "level curve" is locally a flat (in the z dimension ... 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)
