WebExplanation for the correct option: Step 1. Given that x 2 + 2 x y s e c θ + y 2 = 0. Comparing this equation with the general equation a x 2 + 2 h x y + b y 2 = 0, We get. a = 1, b = 1 and. 2 h = 2 s e c θ. ⇒ h = s e c θ. We know the angle between the two lines given by. WebThe leading principal minors are 1, −a 2, and −a 2.. Thus if a ≠ 0 the matrix is indefinite.. If a = 0, we need to examine all the principal minors to determine whether the matrix is positive semidefinite.In this case, the first-order principal minors are 1, 0, and 1; the second-order principal minors are 0, 0, and 0; and the third-order principal minor is 0. booking deferred tax
