Nature of quadratic form
WebThe standard form of quadratic equation is ax 2 + bx + c = 0, where 'a' is the leading coefficient and it is a non-zero real number. This equation is called 'quadratic' as its degree is 2 because 'quad' means 'square'. Apart from the standard form of quadratic equation, a quadratic equation can be written in other forms. WebSince the eigenvectors of A are orthonormal, C − 1 = C T. Suppose we define a transformation x = C X. Then the equation becomes: x T A x = ( C X) T A C X = X T D X = λ 1 X 1 2 + λ 2 X 2 2 +... + λ n X n 2. It follows from this that a quadratic form is positive-definite if and only if all its eigenvalues are positive.
