Inner Product Spaces: Inner product, length, and angle
Inner products on real vector spaces
Consider the vector space #\mathbb{R}^3# with standard inner product.
What is the inner product of the vectors #\vec{x}=\rv{-3,1,-1}# and #\vec{y}=\rv{1,3,-1}#?
What is the inner product of the vectors #\vec{x}=\rv{-3,1,-1}# and #\vec{y}=\rv{1,3,-1}#?
| #\dotprod{\vec{x}}{\vec{y}}=# |
