# Math Help - vector problem part duex

1. ## vector problem part duex

Let = (4, -1, 10) and = (-7, 0, 10) be vectors. Find the scalar, vector, and orthogonal projections of onto .
I don't understand how you would find vector, and orthogonal projections?

2. $proj_A B = \frac{{A \cdot B}}{{A \cdot A}}A$

3. but what are scalar, vector, and orthogonal projections what is the difference between the 3?

4. ok update what is the formula for orthogonal projection?
