Directional Derivative 2
This applet illustrates the concept of directional derivative.
- Set the coordinates of point with the X and Y sliders.
- Set the direction of the unit vector with the Angle slider.
- Observe the curve that results from the intersection of the surface of the function with the vertical plane corresponding to .
- The directional derivative of the function at the point along the direction of the vector is the slope of the tangent line to the previous curve at .
