Vector formula of polarization identity in junior middle school mathematics
There are many formulas to remember in junior high school mathematics learning, so what is the vector formula of polarization identity? Let's take a look together.

The vector formula of polarization identity introduces that polarization identity is an important equation that connects inner product with norm, and it is a formula that expresses inner product with norm. Let h be the inner product space and ‖ be the norm (‖) derived from the inner product. The following equation is usually called polarization identity: (x, y) = (1/4) (‖ x+y ‖ 2-‖ when h is a real space. When h is a complex space, (x, y) = (1/4) (‖ x+y ‖ 2-‖ x-y ‖ 2+i ‖ x+iy ‖ 2-i ‖.
