Question

Write formula for vector or cross product of two vectors.​

Answer 1

Answer:

please mark me as brainliest

Explanation:

We can use these properties, along with the cross product of the standard unit vectors, to write the formula for the cross product in terms of components. Since we know that i×i=0=j×j and that i×j=k=−j×i, this quickly simplifies to a×b=(a1b2−a2b1)k=|a1a2b1b2|k.

Answer 2

The equation to calculate a cross product is pretty simple. The cross product between vectors A and B is equal to the magnitude of vector A multiplied by the magnitude of vector B multiplied by sine of the angle between them. That gives you the magnitude of your answer.
