## Homework Statement

Verify using an example that a(b+c) is not equal to ab+ac. (This means that addition does not distribute over the dot product.)

Vector A be in the y direction (Ax=0 , Ay=1 , Az = 0)

Vector B be in the x direction (Bx=1 , By=0 , Bz = 0)

so, Vector A×B components:

x = Ay * Bz - By * Az = 0

y = Az * Bx - Bz * Ax = 0

z = Ax * By - Bx * Ay = -1

so,

AxB = (0 , 0 , -1)

would this work?
