Question

vector i cross vector j​

Answer 1

Answer:

vector I cross vector j gives 1

Answer 2

Answer:

is equal to K

Step-by-step 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.
