1. On the top right, click on the "rotate" icon between the magnet and the cube to rotate the diagram (you can also change the speed of rotation).[br][br]For the plane,[br]2a. The first three sliders [color=#c51414][b]n[/b]x[/color], [color=#0a971e][b]n[/b]y[/color] and [color=#1551b5][b]n[/b]z[/color] represent the components of [b]n[/b], the normal vector of the plane Π.[br]2b. Use the fourth slider to change the value of k in the equation of the plane Π: [b]r[/b].[b]n[/b] = k.[br][br]For the line,[br]3a. The first three sliders [color=#c51414][b]a[/b]x[/color], [color=#0a971e][b]a[/b]y[/color] and [color=#1551b5][b]a[/b]z[/color] represent the components of [b]a[/b], the position vector of the line [i]l[/i].[br]3b. The next three sliders [color=#c51414][b]b[/b]x[/color], [color=#0a971e][b]b[/b]y[/color] and [color=#1551b5][b]b[/b]z[/color] represent the components of [b]b[/b], the direction vector of the line [i]l[/i].[br]3c. You can use the λ slider to change the value of λ to show how the point with position vector [b]r[/b] = [b]a[/b] + λ[b]b[/b] traces out a line.[br][br]4. Use the checkboxes to see the following:[br][list][br][*] The angle between the plane Π and the line [i]l[/i];[br][*] The projection of the line [i]l[/i] on the plane Π;[br][*] The reflection of the line [i]l[/i] in the plane Π.[br][/list]
