Question

How do I determine the vector projection of a vector?

Answer 1

Please see the explanation below

Explanation:

The vector projection of `vecb` onto `veca` is

`proj_(veca)vecb=(veca.vecb)/(|veca|^2)veca`

Calculate the dot product

`=veca.vecb`

and calculate the modulus of `veca`

`=||veca||`
