If find the magnitude of

Given and


We need to find the magnitude of the vector.


Recall the cross product of two vectors and is



Here, we have (a1, a2, a3) = (2, 1, 0) and (b1, b2, b3) = (1, 1, 1)






Recall the magnitude of the vector is



Now, we find.





Thus, the magnitude of the vector =
