For the given vectors u and v, find the cross product u × v. u = 7i − j, v = −7j + k

Question

For the given vectors u and v, find the cross product u × v.

u = 7i − j,  v = −7j + k

u × v =

Answer 1

Hi Kyle,

So you'd need to set up a determinant where the first row is, in order: unit vectors i, j, k.

Row 2: coordinates of vector u.

Row 3: coordinates of vector v

I go over the rest in the video.

Cheers!
