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?
