Exercise: We saw earlier how to construct the 2×2 matrices that rotate a vector, that reflect a vector across the 45° line y=x, or that project onto the x- or y-axes. The goal of this problem is to construct the matrix that projects a vector onto the line that makes an angle of θ with the x-axis. (We're implicitly using the fact that the function
