Tangent plane and normal line to a surface
This applet illustrates the computation of the normal line and the tangent plane to a surface at a point .
- Select the point where to compute the normal line and the tangent plane to the graph of using the sliders.
- Check the box Normal line to plot the normal line to the graph of at the point , and to show its equation.
- Check the box Tangent plane to plot the tangent plane to the graph of at the point , and to show its equation.
- Enter a new function and repeat the previous steps.
