Dot Product

Dot product in $R^2$ ?

• Dot product of 2 vectors is the scalar
• u o v = u1v1 + u2v2
• Length of u is ;; square root of dot product

Dot products in $R^3$

• Distance between two points, d(u,v) is norm of vector $v-u$

Can be used to determine whether vectors are Orthogonal

Order doesn’t matter
