What does the cross product of two vectors represent in mathematics?
The cross product of two vectors in mathematics represents a new vector that is perpendicular to both of the original vectors. It is used to calculate the area of a parallelogram formed by the two original vectors and to determine the direction of a resulting force in physics.
What does the cross product represent in vector algebra?
The cross product in vector algebra represents a new vector that is perpendicular to the two original vectors being multiplied. It is used to find the direction of a vector resulting from the multiplication of two vectors.
What is the relationship between the cross product and the magnetic field?
The cross product is a mathematical operation used to calculate the direction of a vector resulting from the interaction of two other vectors. In the context of electromagnetism, the cross product is used to determine the direction of the magnetic field generated by a current-carrying wire. The magnetic field is perpendicular to both the current flow and the direction of the wire, as determined by the right-hand rule.
What is the right hand rule used for when determining the direction of the cross product?
The right hand rule is used to determine the direction of the cross product in mathematics and physics. It helps to find the perpendicular direction to two given vectors by using the orientation of the right hand.
How the cross product of two vector is negative?
The cross product of two vectors can result in a negative vector if the two original vectors are not parallel to each other and the resulting vector points in the direction opposite to what is conventionally defined as the right-hand rule direction. In essence, the orientation of the resulting vector determines if it is negative or positive.

Why cross product does not obey commutative property?
The cross product of two vectors is defined as a × b sinθn Where the direction of Cross product is given by the right hand rule of cross product. According to which stretch the forefinger of the right hand in the direction of a and the middle finger in the direction of b. Then, the vector n is coming out of the thumb will represent the direction. As direction of a × b is not same to b × a. So it does not obey commutative law.

Why you use sin in cross product?
The sine function is used in the cross product because the magnitude of the cross product of two vectors is determined by the area of the parallelogram formed by those vectors. This area is calculated as the product of the magnitudes of the vectors and the sine of the angle between them. Specifically, the formula for the cross product (\mathbf{A} \times \mathbf{B}) includes (|\mathbf{A}||\mathbf{B}|\sin(\theta)), where (\theta) is the angle between the vectors, capturing the component of one vector that is perpendicular to the other. Thus, the sine function accounts for the directional aspect of the vectors in determining the resultant vector's magnitude and orientation.

How do you multiply vectors in 3D?
To multiply two vectors in 3D, you can use the dot product or the cross product. The dot product results in a scalar quantity, while the cross product produces a new vector that is perpendicular to the original two vectors.
Why you use cosine theta with cross product?
Normally you use sine theta with the cross product and cos theta with the vector product, so that the cross product of parallel vectors is zero while the dot product of vectors at right angles is zero.
When does the magnitude of dot product and cross product of vectors is equal?
If x is the angle between the two vectors then the magnitudes are equal if cos(x) = sin(x). That is, when x = pi/4 radians.
Why the cross product of two vectors in plane is directed perpendicular to the plane?
because that is the def. of a cross-product!
What is the geometrical meaning of cross product?
The cross product can be said to be a measure of the 'perpendicularity' of the vectors in the product. Please see the link.
