Try the following in GeoGebra:
Example 1: Vector Cross Product:
Find the area of the parallelogram formed by vectros u and v:
Visualize the plane:
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.
PLU Decomposition with GeoGebra:
Example 1: Vector Cross Product:
- u = Vector((3,0,0))
- v = Vector((0,2,0)
- w = Cross(u,v)
- m = |w|
Find the area of the parallelogram formed by vectros u and v:
- p1 = Point({0,0,0})
- p2 = Point((0,0), v)
- p3 = Point(p2, u)
- p4 = Point(p3, Vector(-v))
- Area = Polygon({p1,p2,p3,p4})
Visualize the plane:
- 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)
