Question

Is cross product $\sin$ or $\cos$?

Answer 1

Determining whether cross product is $\sin$ or $\cos$ :

The cross product of two vectors is equal to the product of the magnitude of the vectors and the sine of the angle between them.

It can be written as:

$\overrightarrow{A}\times \overrightarrow{B}=\left|A\right|\left|B\right|\sin \left(\theta \right)$$\eta$

Therefore, cross-product includes $\sin$.
