Example 12.6.2: Finding directions of maximal and minimal increase. In engineering notation it would be -2 times a unit vector I, that's the unit vector in the X direction, minus four times the unit and I should say approximately 'cause I still rounded, The unit vector in this example ends up being the cos and sin of the angle formed by the original vector and the x-axis. What is the significance of finding a unit vector? @ceztko You have meant probably collinearity is equivalent to that norm of vector product = 0.. @Widawensen: yes, correct. where it's initial point, or it's tail, is sitting at the origin. So inverse tangent, it's about 63.4 degrees roughly.
Alternative way (also mentioned in another answer): As you probably know, the cross product of two vectors $v_1, v_2$ yields a third vector $w$ which is perpendicular to the initial two vectors and the length of that vector equals the area of the parallelogram with sides $v_1$ and $v_2$. Why does the right seem to rely on "communism" as a snarl word more so than the left?
