The orthogonal projection of b onto a is given by:
Just plug n' chug.
Let a = (8, 3, 5) and b = (8, -10, -5) be vectors. Find the scalar, vector, and orthogonal projections of b onto a .
I was able to easily find the scalar and vector projection, but I need help on orthogonal projection. All I know is that the dot production must equal 0.
Scalar projection =
Vector projection = ( , , )
