Quick cross product question
Hi, with the cross product of two vectors,
eg:
(x,y,z) = (y1*z2 - z1*y2, z1*x2 - x1*z2, x1*y2 - y1*x2)
Am I supposed to also get the absolute value for each of the x,y,z as well?
eg:
(x,y,z) = (|y1*z2 - z1*y2|, |z1*x2 - x1*z2|, |x1*y2 - y1*x2|)
THanks
edit:
Btw im asking because im learning to calculate the equation of a plane and in this article i got two vectors
4, 6, 1
3, 7, 6
and they give the cross product as 29, 21, 10, where i got 29, -21, 10 instead.
