Differentiate dot product and cross product

WebCross product or vector product. If the product of two vectors is a scalar quantity, the product is called a scalar product or dot product. If the product of two vectors is a vector quantity then the product is called vector product or cross product. The dot product is defined by the relation: A . B = AB Cos θ. WebSep 3, 2024 · $\begingroup$ @NamanAgarwal The cross product creates a new vector, so the rank does not change. So the tensor product is very different from the cross product. In 3 dimensions, the cross product can be realized by applying the exterior derivative on the 1-form, followed by the Hodge dual operation.

WebAnd the other, I guess, major difference is the dot produc, and we're going to see this in a second when I define the dot product for you, I haven't defined it yet. The dot product results in a scalar. You take the dot product of two vectors, you just get a number. But in the cross product you're going to see that we're going to get another vector. malolos scholarship https://meg-auto.com
