# 44+ Vector Projection Formula

**44+ Vector Projection Formula**. Projection of vector a on b formula can be denoted by projba. Similarly, projection of a in the direction of b is a cosθ.

I properties of the dot product. Assume that the vector w projects onto the vector v. Refer to the note in pre linear algebra about understanding dot product.

### The vector projection of a vector a on a nonzero vector b is the orthogonal projection of a onto a straight line parallel to b.

= ^ where is a scalar, called the scalar projection of a onto b, and b̂ is the unit vector in the direction. The signed length of is the scalar projection of along denoted. This vector will run along. Vector projection formula the vector projection is of two types:
