The Method of Least Squares,will call it the . of .-with the property that . = . is the best choice for a solution of . = . (even when there is no solution) in a very specific sense. The mate of . is defined in Section 3. First, the notion of the transpose of a matrix and a few properties of transposes need to be explained.

Similarity of Matrices,f as describing such a transformation by giving the relation between the original values of the . numbers and their values after the transformation is applied. The matrix of coefficients of a linear substitution that arises in this way is .. This is one reason that square matrices are especially important.

Matrix Multiplication,linear” because an expression which involves a sum of multiples of variables is called a .* ., which is to say, a polynomial in which each term contains exactly one variable and that variable occurs to the first power.

Matrices with Rational Number Entries,d. The operation of composition of linear substitutions is defined in the same way as before, and it corresponds in the same way as before to an operation of matrix multiplication of matrices with rational entries.

The Spectral Theorem,nd useful theorems in all of mathematics, and because the main content of the theorem can be formulated in a way that is purely algebraic (though not purely linear), until the limit notion enters at the last step (Section 7).
