Question

What is the cross product of `[-3, 5, -3]` and `[4, -11, 11]`?

Answer 1

`vec C=22i+21j+13k`

Explanation:

`"the cross product of two vector is given as :"`
`vec A=(a,b,c)`
`vec B=(d,e,f)`
`vec C=vec A X vec B`
`vec C=i(b*f-c*e)-j(a*f-c*d)+k(a*e-b*d)`
`"Thus:"`
`vec C=i(5*11-11*3)-j(-3*11-(-3*4))+k((-3)*(-11)-5*4)`
`vec C=i(55-33)-j(-33+12)+k(33-20)`
`vec C=22i+21j+13k`
