3.1.41 Curves of the 2nd order
condition: On the line \( x+5=0 \) find a point equally distant from the left focus and the upper vertex of the ellipse \( x^{2} / 20+y^{2} / 4=1 \).
Study of curves of the second order and their characteristics. Ellipse, hyperbola, parabola. Finding eccentricities, foci, focal radii, major and minor axes, including imaginary, canonical equations and plotting.
