There are various physical situations in which the cross product naturally arises, for example in various relationships between electricity and magnetism. Another example is torque (the rotational equivalent of "force"): torque depends on the distance from the reference point and on the force. It also depends on the angle between the two (including the direction in the "distance"). Finally, the torque can conveniently be defined as having a "direction" that points in the axis of the resulting rotation (or angular acceleration). This gives you all the characteristics of a cross product.
The derivative of the cross product with respect to a given variable is a vector that represents how the cross product changes as that variable changes.
The right hand rule is important in vector cross product calculations because it determines the direction of the resulting vector. By using the right hand rule, you can determine the direction of the cross product by aligning your fingers in the direction of the first vector, curling them towards the second vector, and the direction your thumb points in is the direction of the resulting vector. This rule helps ensure consistency and accuracy in vector calculations.
The right-hand rule is important in the context of the cross product operation because it determines the direction of the resulting vector. By using the right-hand rule, you can determine whether the resulting vector points in a positive or negative direction relative to the two original vectors being crossed.
The cross product gives a perpendicular vector because it is calculated by finding a vector that is perpendicular to both of the original vectors being multiplied. This property is a result of the mathematical definition of the cross product operation.
No, the determinant and the cross product are not the same. The determinant is a scalar value that represents the volume scaling factor of a matrix, while the cross product is a vector operation that results in a new vector perpendicular to the original vectors.

0 is a cross product of a vector itself

The derivative of the cross product with respect to a given variable is a vector that represents how the cross product changes as that variable changes.
The cross product can be said to be a measure of the 'perpendicularity' of the vectors in the product. Please see the link.

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.
because that is the def. of a cross-product!
