... Depending upon the sign of the coefficients of z12 and z22 , the curve can be a hyperbola or an ellipse (equal signs). Equal coefficients give a circle, or a right hyperbola if one is the negative of the other. If n=3, the points that satisfy the equations lie on ellipsoids or hyperboloids, and in a ...

... Thus S + T is closed under addition and scalar multiplication; in other words, it satisfies the two requirements for a vector space. (b) If S and T are distinct lines, then S + T is a plane, whereas S ≤ T is not even closed under addition. The span of S ≤ T is the set of all combinations of vectors i ...

... matrix has nine real entries, but the condition of orthogonality imposes three diagonal and three (symmetric) off-diagonal conditions, so there are three independent real parameters. The set of orthogonal 3×3 matrices divides into two subsets — one of matrices with determinant −1, the other of matri ...
