Try the following in GeoGebra:


Example 1: Vector Cross Product:

Code: [Select all] [Expand/Collapse]

1. u = Vector((3,0,0))
2. v = Vector((0,2,0)
3. w = Cross(u,v)
4. m = |w|

Find the area of the parallelogram formed by vectros u and v:

Code: [Select all] [Expand/Collapse]

1. p1 = Point({0,0,0})
2. p2 = Point((0,0), v)
3. p3 = Point(p2, u)
4. p4 = Point(p3, Vector(-v))
5. Area = Polygon({p1,p2,p3,p4})

Visualize the plane:

Code: [Select all] [Expand/Collapse]

1. x-4y-2z=3

Draw a plane through 3 points:

A = (1,3,-1); B = (3,5,5); C = (1,6,5); plane(A, B, C)


Try to take derivatives, see examples here.
