Do you care about whether we simplify fractions or not? Also, this overlaps so incredibly well with calculus 3, except for the fact that we did all of this in August.

I think the best way to understand projections is to draw and look at pictures, however, I see now that we can only draw so many dimensions:(

Bonus point attempt: If we have a vector/point that can be written as a coordinate with respect to a bunch of axes then "the projection of that vector with respect to those axes" is just equal to that coordinate. If you have a fly on a piece of paper and shine a light on it from directly above, its feet are touching its shadow.

So for an orthonormal matrix U whose columns form the basis for W; UᵀUx = x, but UUᵀx = x̑.

Could a geometrical conclusion to proof theorem 9 be the fact that the (y-v) vector is the hypotenuse which is always the longest side of a right triangle?

Also, where does the formula for z hat apparate from?
