Khan Academy: Linear Algebra: Another Example of a Projection Matrix

Curated by ACT

A video lesson working another example for finding the projection of an arbitrary vector onto a specific subspace in R3. The basis of the subspace is a 3 x 2 matrix. Uses an alternate method for find the transformation matrix that includes finding the transformation matrix for the projection onto the subspace's orthogonal complement. [21:35]
