HW 2.2
Question 10/11 of 2.2, how do we find the matrix of the reflection if we don't have anything specific that we're reflecting?

Hi Ksvatos, The goal for number 10 is finding a matrix such that ANY vector in the space becomes an orthogonal projection onto line L. You can find such a matrix by using definition 2.2.1 where w1=4 and w2=3. w is a nonzero vector parallel to L and spans L. You can see how they derive that matrix under the orthogonal projections section.
