## The Attempt at a Solution

Hey everyone, I've been asked to find the "orthogonal projection" on this matrix, this is part B to a question; part A had me use matrix multiplication to find the image of the point x = (4,3) under the reflection of 120 degrees with the positive x-axis. The above matrix was what I came up with, before multipying by x to get some irrational values, of course. But I haven't a clue how to perform orthogonal projection, if anyone could help I'd appreciate it.

Serenity now :0)
