What is Cross product and Dot product

1.	What is Cross product and Dot product
Answer» Answer: The dot PRODUCT and cross product are methods of relating two vectors to one another. The dot product is a SCALAR representation of two vectors, and it is used to find the angle between two vectors in any dimensional space. For vectors and , the dot product is . The cross product is a vector orthogonal to three-dimensional vectors and , and can be used to determine the area or volume of a parallelogram DEFINED by , , and . For vectors and , the cross product is , which is the DETERMINATE of a three-by-three matrix. Two vectors are parallel if their cross product is equal to zero, .
