PRODUTO MISTO ✅ DEMONSTRAÇÃO

MIXED PRODUCT DEMONSTRATION ✅ ANALYTICAL GEOMETRY IN SPACE If the non-zero vectors u, v and w (the number does not matter) have representatives AB, CD and EF belonging to the same plane π, they are said to be coplanar. Any two vectors are always coplanar. 1) Determine the volume of the parallelepiped determined by the vectors... 2) Use the mixed product to show that the vectors a=(1, 4, -7), b= (2, -1, 4) and c=(0,-9,18) are coplanar.
