Why some quantities are taken as dot product and some quantities are taken as cross product?
Answers
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, .
Explanation:
Pls follow me if u ever have any doubts
Answer:
. and product(x) are the same and we can use it everywhere needed
Explanation:
in some quantities we use dot product bect if we use criss product then in some cases it could be considered as X.
