I am trying to figure out the following
If R2 = 1.043j -1.143k
Then how can
R2 = 1.547
If R2 = 1.043j -1.143k
Then how can
R2 = 1.547
A vector can't be equal to a number. However, [itex]\vec R_2=1.043\vec j-1.143\vec k[/itex] implies that [itex]|\vec R_2|\approx 1.547[/itex]. This follows immediately from the definition of [itex]|\vec x|[/itex] for arbitrary [itex]\vec x[/itex], or if you prefer, from the Pythagorean theorem. It doesn't have anything to do with the cross product.hatchelhoff said:I am trying to figure out the following

A vector cross product is a mathematical operation that combines two vectors to create a new vector that is perpendicular to both of the original vectors.
The cross product is calculated by taking the determinant of a 3x3 matrix formed by the two original vectors, and then finding the vector that is perpendicular to both of the original vectors using the right-hand rule.
The cross product is used to find the direction and magnitude of a vector that is perpendicular to two given vectors. It is also used in various applications such as physics, engineering, and computer graphics.
The dot product is a scalar value that represents the projection of one vector onto another, while the cross product is a vector that is perpendicular to both of the original vectors. The dot product also results in a scalar value, while the cross product results in a vector.
The cross product has many applications in physics, such as calculating torque and angular momentum. It is also used in engineering for calculating forces and moments in structures. In computer graphics, the cross product is used for lighting and shading calculations to create realistic 3D images.
