9.1 matrix of a quad form
... All diagonal versions of q have the same coefficient sign distribution, i.e., the same number of positive, negative and zero coeffs. This sign distribution is the same as the sign distribution of the eigenvalues of the matrix of q since one of the diagonal forms of q has the eigenvalues as the coeff ...

... area of a square is known, how can we determine the length of its side? For example, to make a square tabletop with area of 9 m2, we have to find out the length of its side first. It is same as finding a number whose square is equal to 9. We have two answers, namely 32 = 9 , and (−3) 2 = 9 . Since l ...
