9.2 Dot Products and Projections – Functions, Trigonometry, and …
In Section 9.1, we learned how add and subtract vectors and how to multiply vectors by scalars. In this section, we define a product of vectors. We begin with the following definition. Given …
For instance, the function h(x) = add(x,x) can be defined by h(x 0) = add(P1(x 0),P1(x 0)). Here k= 2, n= 1, the role of f(y 0,y 1) is played by add, and the roles of g 0(x 0) and g 1(x 0) are both …

matrices - Multiplication of the projection matrix with a vector ...
In the second proof I start with $X(X'X)^{-1}X'X_2 = X_2$ and pre-multiply both sides of the equation by $X(X'X)^{-1}X'$ which gives $X(X'X)^{-1}X'X(X'X)^{-1}X'X_2 = X(X'X)^{-1}X'X_2$. …
