DHS - 4.1
№1.27. Be the canonical equation of: a) the ellipse; b) hyperbole; c) a parabola; A; The - the point lying on the curve; F - focus; and - a big (real) sex; b- small (imaginary) sex; ε - eccentricity; y = ± kx - the equations of the asymptotes of the hyperbola; D - the headmistress of the curve; 2c- focal length. Given: a) A (-3, 0); B (1; √40 / 3); b) k = √2 / 3; ε = √15 / 3; a) D: y = 4.
